FT8 Adoption: The New Cool Thing

The new cool digital mode for amateur radio is FT8, made possible by Joe Taylor/K1JT and the WSJT software. At first, FT8 seemed like just the next digital mode to try but it is turning out to have a bigger impact than that. Jeff/KE9V recently posted about the popularity of FT8 here:

FT8 is so far out in front that other digital modes are a foregone conclusion. CW only remains relevant because of its popularity in contests. Even phone, the Holy Grail of wannabe HF operators everywhere, is a nearly forgotten mode compared to FT8.

This reminded me of some of the classic research on adoption of new innovations. What are the factors that cause a new thing to really take off versus languish on the shelf? How do these apply to the quick adoption of FT8?

Diffusion of Innovations

In Diffusion of Innovations, E. M. Rogers lists five factors will influence how quickly a new innovation gets adopted:

Relative Advantage: The degree to which the innovation is superior to ideas it supersedes.

If an innovation is clearly superior to the present way of doing things, people will be more likely to adopt it without too much concern about its usefulness. If it’s not clearly better, people will tend to question whether it is worth the trouble of changing.

Compatibility: The degree to which the innovation is consistent with existing values, past experiences, and the needs of the user.

If an innovation is similar to existing practice and blends in well with user needs and expectations it is more likely to be adopted.  If it requires change on the part of the user or represents an inconsistency with the user’s past experience, it may be rejected.

Complexity:  The degree to which the innovation is relatively difficult to understand and use.

The more complex something is, the more likely people will reject it because “it’s just too much trouble.”  Understandable ideas will tend to be considered more carefully and are more likely to be adopted.

Trialability:  The degree to which an innovation may be tried on a limited basis (in other words, without committing to full-scale, total operational change.)

The easier it is for an individual or organization to try something out without being fully committed, the more likely they will give a new innovation a try.  If the innovation can only be tried with full-scale change and great expense, it will tend to get rejected.

Observability:  The degree to which the results from the use of an innovation are visible and easily communicated to users and other decision-makers.

If the results of an innovation are difficult to measure or see, rejection is more likely.  If the results are clearly visible, then the adopting individual or organization can more easily correlate the results to the innovation.  Generally, a decision-maker wants to be sure that the intended results can be measured, otherwise how can the innovation be evaluated?

Adoption of FT8

It is very clear that FT8 has a strong relative advantage to other modes. Just listen to the many comments from hams like “the band conditions are really bad but I’m still making contacts.” One could argue that FT8 is not that compatible with existing operating habits (think CW or SSB) but the mega-trend of using “sound card modes” is a huge enabler. For some time now, hams have been using the PC platform as a digital signal processing engine, using the sound card to handle the analog-to-digital conversion (and back). Perhaps this traces back to PSK31 as one of the major forces that caused hams to connect their transceivers to their computer. In that sense, FT8 is very compatible with existing sound-card-enabled stations, making it strong on compatibility and trialability. Just load up the WSJT-X software and give it a try. Of course, observability is strong too…now I’m making QSOs when I wasn’t before.

There is a bit of a learning curve with FT8, which could be a barrier to adoption. You need to learn the software and fiddle around with the settings to make it work. But for many hams, this is not a barrier but a fun challenge to take on. Most of us like to try new things, as long as they aren’t too frustrating.

The final point I’ll make is that the popularity of FT8 reinforces my contention that Ham Radio Is Not For Talking. FT8 is all about making a radio contact and does not enable conversations. Sure, most hams like to talk (usually about radios) but when the bands are poor they like making radio contacts via FT8. Making QSOs is king.

Those are my thoughts. What do you think?

Solving the Baofeng Cable Problem

baofeng b5The various models of Baofeng handheld transceivers keep popping up everywhere. At prices less than $50, radio amateurs (including veterans and newbies) are scarfing up these radios. See my postings or check out PD0AC’s blog for more information.

Also very frequently, the new owner of such a radio finds that they cannot figure out how to program it. Of course, the solution is “use the programming software” which is often helpful (and often not). The really gnarly problem that usually surfaces is getting the programming cable to work.

It appears that many of the cheap Baofeng USB programming cables use a clone of the Prolific PL-2303 chip that is not supported by the latest Windows driver. This Miklor web page does a good job of explaining the driver problem and giving some helpful advice. (Actually the Miklor site has tons of information on these radios, so check it out.) I’ll also note that the same cable can be used to program a Wouxun radio, so the same remedies apply. Using the info on the Miklor site allowed me to get my Baofeng/Wouxun cable working with my old Windows XP computer. When I bought a new notebook PC, it came with Windows 8 installed, which I later “upgraded” to Win 8.1. (I will spare you the sad story of dealing with Win 8 and 8.1)  Anyway, I have not gotten the Baofeng cables to work on Win 8 or 8.1, even following the Miklor advice.

I started using the Chirp programming software, an open source application that supports a wide variety of radios. (I have found the supplied Baofeng and Wouxun software to be, uh, well, crapware. It can be made to work but it is a pain.) While the Chirp software is not bug free and is in perpetual beta, it basically works well and does a great job of supporting a wide range of radios. I noticed that the Chirp Cableguide recommends the use of programming cables with an FTDI USB chip. I found this one on Amazon for $19, a little more expensive than the cheapo cables but not bad.  I plugged it into my Win8.1 computer and it started working immediately. I did not load any drivers, Windows actually did its job and took care of it for me. In minutes, I was programming a variety of Baofeng and Wouxun radios. Success!!!

My strong recommendation at this point is to use the Chirp software and get a FTDI-based programming cable. You will be a much happier Baofeng or Wouxun owner.

CQ WW VHF Contest Certificate

This certificate for the CQ Worldwide VHF Contest arrived in the mail today, 1st Place Single Operator All Band for Colorado. Most of these contest awards take so long to arrive, I have usually forgotten all about the contest by the time they show up in the mail.
K0NR CQ WW VHF

Last year, I had a pretty good run at it with an excellent 50 MHz sporadic-e opening on Saturday that ran up the QSO and grid totals. See my previous report on the contest here.

How Many Online Logbooks Do We Need?

I recently commented on the ARRL Log Book of the World when they turned on support for the VUCC Award. This was a long time in coming and is a great addition to the program.

About a week later, I was poking around my qrz.com page and found that there are 32 QSOs sitting there waiting for me to confirm them. What? QSOs on qrz.com? It seems that they have added a “logbook” feature which supports keeping a log of radio contacts and verifying these contacts with other radio amateurs. I participated in the ARRL January VHF Sweepstakes and some of the contest participants uploaded their log to qrz.com, which caused these QSOs to show up in my logbook.

So now there are at least 3 online amateur logbooks available: eQSL, LoTW and qrz.com. So far, I have only paid attention to LoTW, uploading all of my contacts made since 2002. I have ignored eQSL since these contacts do not count towards ARRL awards. Yes, that does mean I am old school and think that DXCC, VUCC and WAS from the ARRL are the real deal and anything else is an imitation. CQ Amateur Radio is accepting eQSL confirmations and has a decent awards program, but I haven’t focused on any of those yet.

You can see what is going to happen…the amateur population will split across these different logbooks and it will be difficult to transfer “credit” between them. You’ll have a mishmash of confirmed QSOs that include the good old paper variety and several different electronic logbooks.

I am not sure what to do about this but I’ll probably just focus on LoTW. What do you think?

73, Bob K0NR

Logbook of the World – What Next?

ARRL’s Logbook of the World has gotten mixed reviews from the ham community. KB6NU asks Is it more trouble than its worth?, while VE3OIJ says he will probably never use it. On the other hand, K2DBK says you really should use it. The biggest beef seems to be around the level of security (and hassle) built into the logbook system. Someone said “LoTW has more security than my online bank.” Probably true.

I have been loading my ham radio log data into the Logbook of the World for QSOs back to 2002. Although I’ve seen quite a few QSL matches via LoTW, it has not provided any real benefit to me.

Last week, that changed. The ARRL turned on support for the VUCC award. Lately, I have been on the air for most of the VHF contests and not much else. So when I logged into the LoTW web page, I found that I have 123 grids confirmed on 6 Meters, which would qualify me for 50 MHz VUCC. (Actually, I had already qualified for this award years ago, the hard way, with paper QSLs.)

I am still working towards 144 MHz VUCC and have been working on getting QSL cards for these contacts. To be honest, I have turned into a QSL Slacker. I manage to respond to every request for a QSL …eventually, but I have been a slacker on pursuing QSLs that I need for awards. You know the reasons: it takes time, it costs postage, it is a hassle.

The answer is obvious: we need to confirm QSLs electronically. Push a button, upload your log and receive the instant gratification of a confirmed QSO. Life is too short to mess around with cards. Not that I don’t like getting The Real Thing in QSL cards…there is nothing like receiving a well-designed card and holding it in your hands.

The challenge is also obvious… the ARRL needs to turn on support for more awards (way beyond DXCC, WAS and VUCC) with the goal of providing a benefit back to the users of LoTW. Otherwise, the number of people bothering to submit logs will remain low, limiting the success of LoTW.

This Spewed Out of the Internet #17

The summer is flying by and it has been difficult to keep up with the blog. Here are a few things that just spewed out of the internet.

This week there is a nasty wildfire burning west of Boulder which has already consumed 92 structures. (Take a look at some of the photos here.) We have gotten used to the occasional wildfire in the west, some big, some small. This one seems to have spread rapidly and damaged many homes in a short time. And its not over yet. And yes, the local amateur radio community is actively helping out.

K3NG writes about a situation concerning a public service event. He makes some really good points about the amateur radio role in such events. Sometimes I see radio amateurs working events and not really providing much value. This gives us some on-the-air practice but that may not be enough to justify participating.

The Southgate ARC has an item about keeping the AM mode alive. To me, AM definitely means ancient modulation, clearly approaching the Duty-To-Die phase. Please end the life support on this mode and let it slip away. It really will be better for everyone.  (OK, I suppose these guys are just having fun…hard to knock that. But they could do it with half the bandwidth. )

Back to the future with a reworked Commodore 64. I could see getting one of these PCs.

Here’s a good article from unplggd on emergency preparedness from a tech point of view (but not necessarily amateur radio). It’s worth a read.

Those Compact Florescent Light (CFL) bulbs are gaining in popularity. I believe they are an ecological time bomb because of their mercury content. See this article for more information. Oh, and if they aren’t designed well, they tend to radiate radio frequency interference.

USB Cable Experiment

Given all of the electronic gadgets in my life, I end up carrying quite a few cables and power adapters around with me. Somehow these things always end up in a tangled mess inside by backpack/computer bag. It often takes me days to untangle them after a trip. Although annoying, I didn’t really give it too much thought as it just seemed part of having all these gadgets.

This weekend, I decided to apply the scientific method to aid in my understanding of how these cords get tangled. I did a controlled experiment using two USB cables carefully laid on a flat surface a few centimeters apart:

I left the cables in a locked room, with windows closed so that wind or other outside forces could influence the outcome. The above photograph was recorded at 9 PM on Day 1.

The next morning, I returned to the room and verified that the door was still locked and that nothing had been disturbed. To my surprise, I found the two cables in this condition, recorded by photograph at 9 AM on Day 2:

Apparently, the cables are able to move on their own and create a tangled mess without human intervention. There must be some physical force present that causes this movement, perhaps the triboelectric effect? I will need to repeat this experiment, perhaps with a video camera capturing any movement.

Has anyone else produced similar results?

Standard USB: Missed It By That Much

usb-cable-mini-bI’ve blogged in the past about the need for standardization, especially when it comes to computer cables and power adapters. I have been feeling quite good about the progress I have been making with my personal collection of electronic gizmos. I’ve noticed that most of them have lined up behind the idea of using a mini-USB (Universal Serial Bus) port for both power and data. Now how cool is that? Someday, I might be able to carry one USB cable and a AC adapter and have it handle all of my information-age cabling needs.

Then I got a surprise: I upgraded my personal mobile phone to an LG enV3. Great, it also has a little USB connector on it, so it will be compatible with my other devices. Bzzzt. Wrong!  It turns out that the enV 3 has a micro USB port which is about the same width but thinner than the mini USB. It seems that the USB Implementers Forum decided that the mini USB was just a bit too fat for slimmed down mobile phones and personal digital widgets. And the mobile phone industry has decided to standardize on this new slimmer connector.

Then I had to admit that I remember when the mobile phone guys announced this new standard. I just missed the fine point about mini vs micro. I thought we were already mini and micro enough!

I see now that the ham radio manufacturers cleverly avoided this whole mess, clinging to that industry giant, the old reliable RS-232 serial port! Their late adopter (never adopter?) behavior has saved them the agony of flipping the USB port.

On a similar note, Apple will apparently never move away from their proprietary iPod connector, so they have also shielded us from the pain and agony of using an affordable, standard connector.

I guess I need to go find a micro-USB to mini-USB adapter somewhere.  Like this one.

Backing Up the Acer Aspire One

Aspire OneI’ve posted a few items about the Acer Aspire One netbook (with SDD and Linux) which have generated some positive comments. See Sweet Little Acer Aspire One PC, More on Netbooks,  and My Tweaks to the Aspire One Netbook.  One thing I’ve noticed is that the Thunderbird email client has a nasty habit of losing a critical file and tossing out all of the email messages. Because of this, I’ve taken a bit more care to backup the email messages and address book (which you should be doing anyway).

Here’s the simple procedure I use to back up the critical folders on the Aspire One onto a USB thumb drive.

Exit all applications

Insert a USB flash drive into one of the USB ports (File Manager should automatically open. If not, open up File Manager manually.)

Click View and select Show Hidden Files. Some of the files we want to copy are hidden, so this let’s us see them.

Select My Disk (over on the left side of File Manager). Then drag the .thunderbird folder over to the USB drive, which will copy the files onto the USB drive. This may take several minutes depending on how many files you have.

Also drag the .mozilla folder over to the USB drive, copying the Firefox bookmarks and other settings

You can copy any other folders that you want to back up

Click the eject drive icon on the right side of the USB drive indicator (left side of File Manager). This closes down the USB drive and prepares it to be removed.

If you ever experience a loss of email information, simply insert the USB drive and drag the .thunderbird folder back onto the Aspire’s main drive (My Disk).

Remember, you don’t have that much SSD drive space on the Linux Aspire, so be sure to delete unneeded email messages and other files.

Podcast: Linux in the Ham Shack

Over the past few years, I have developed the habit of listening to podcasts on my iPod as an alternative to broadcast radio. (See my post from April 2006: Competing for Ears.) Of course, some of my favorite podcasts are on the topic of amateur radio. I’ve noticed that some of them have come and gone, and my interest in them varies over time.

Recently, I just came across a new podcast called Linux in the Ham Shack, by Richard KB5JBV and Russ K5TUX. Richard also does the Resonant Frequency podcast. Both of these podcasts are available via iTunes and probably a whole bunch of other feeds. For you Linux enthusiasts, Russ’s call sign is a vanity call chosen for its Linux significance.

Most of my PCs run some version of Windows, but lately I have gotten more interested in what Linux can do for me. Earlier this year, I took one of my old PCs running Win98 and gave it some new Linux brains (Ubuntu). I have to admit that I have just been running non-ham radio apps such as OpenOffice and Firefox on that machine. I’d like to turn on PSK31, APRS, WinLink and other digital modes so this new podcast sounds like a great resource.

The first few episodes of Linux in the Ham Shack were interesting and helpful, with a nice interplay between Russ and Richard. Keep up the good work, guys!

Managing Twitter Overload

Twitter is The Next Big Thing on the web…sometimes referred to as microblogging.  (For some background on Twitter, see my earlier post: Twitter: Yet Another Web Thing.)  Several of the ham radio bloggers have tried Twitter and have gotten frustrated with it. Steve K9ZW says that

Basically the few unique bits of information passed are overwhelmed by endless droning Tweets about microcosms of banality trying to add value to the mundane.

I think NØHR captured the issue succinctly by describing Twitter as having a poor Signal-to-Noise Ratio.

I suppose this is what you get from a free, web-based communication service that asks you “What Are You Doing?” and gives you 140 characters to form the answer.

My view is that we are living in a world where the barriers to communication have been dramatically lowered, meaning that there is more information flying in our direction than ever before. Twitter is just the latest example of this. If you “follow” a hundred or so people all tweeting away with their What Are You Doing? stream of consciousness,  you are going to end up with a Pile-O-Stuff of questionable value. To make this useful, you must be careful about who and how many people you follow or apply some kind of filtering/sorting mechanism to keep it under control. I noticed that WA4D expressed a similar view.

This is really no different from when we subscribe to other forms of electronic distribution, such as email lists (e.g., Yahoo groups) and RSS feeds. The reality is that you can easily get overloaded by all of the content out there….more than any human has time or energy to read. So be selective…it is the only way to survive the Information Diarrhea Age.

73, Bob K0NR

Followup on 30 Dec:

I guess I should have specifically stated: I am finding value in Twitter….usually in the form of a pointer to an interesting web page or an insightful observation by one of the people I am following. Your Mileage May Vary.

My Tweaks to the Aspire One Netbook

I need to document the tweaks that I made to the Acer Aspire One netbook, so I figured I might as well post them here since someone else may find them useful. All of this info is available with sufficient googling but here’s the condensed version.

Background

The PC is the Acer Aspire One, Linux  version with 8GB SSD, referred to in these previous postings:

https://www.k0nr.com/wordpress/archives/200

https://www.k0nr.com/wordpress/archives/430

My basic approach to hacking this PC is to leave most of it alone and make minimal adjustments:

  • Enable the advanced mode user interface
  • Load Thunderbird in place of the original email client
  • Load a few more games

Enable Advanced Mode

This one is easy. Get into the Terminal mode (AKA linux command line) by pressing ALT – F2 on the keyboard.  Type in: xfce-setting-show which will bring up a window with several icons on it. Click on Desktop to get to the Desktop Preferences and choose the Behavior tab. Now mark under Menus the Show desktop menu on right click option and close the window. Now you can access a much expanded menu selection by selecting a Right Click on the desktop.

See http://www.aspireoneuser.com/2008/07/09/aspire-one-advance-linpus-mode-hack/ for more information or if you find my instructions inadequate.

Load New Software

Now that Advanced Mode is enabled, we’ll go load up some new software. Do a Right Click with the mouse on the desktop to bring up the advanced menu. Select SYSTEM and ADD/REMOVE SOFTWARE, which brings up the dialog box for managing the installed software. It will probably take a little while for it to load the list of available choices. Then use the SEARCH tab to find these software programs and add them in:

  • thunderbird
  • any other programs (I just added a few games)

Follow the prompts to get the software to load and be patient.

Fixing the Main Menu (So Email points to Thunderbird)

There is one more thing to fix. The Desktop Menu icon for “Email” still points to Aspire One Mail, not Thunderbird. You could choose to just live with this and select Thunderbird from the Advanced Menu (Right Click on Desktop). Warning: You can royally screw up your computer if you make an error, so all disclaimers apply!

To change the Desktop Menu, we need to edit one of the files that defines how the menus are configured. This forum discussion has all of the info but I will also summarize it here.

Edit this file using Mousepad or some other editor:

/home/user/.config/xfce4/desktop/group-app.xml

You should be able to use the standard file manager to find this file. A double-click on the file should launch the editor.

Find the line that begins <app sequence=”3″ acs=”email”>
Change AME.desktop to mozilla-thunderbird.desktop
Save the file and reboot the PC (you may want to save the original file somewhere in case you need to reverse this edit). Be Sure to Reboot the PC for this change to take effect.

One More Thing

To stop Aspire One Mail from checking for new messages:

Open Aspire One Mail (you may need to use the advanced menu now for this)
Tools>Options
Uncheck: “Check for Messages Every:” and “Play sound when new messages arrive.”

More on Netbooks

The so-called “Netbook” category continues to get quite a bit of attention. Acer has introduced several new models in the Aspire One line and is intent on winning in this category (aiming for 50% of the market in 2009).

Some pundits have pointed out that even though this category is growing dramatically, you may not see that many of them at the local coffee shop. I have to admit that I have not noticed very many of them in the wild. (The installed base is huge, so it takes quite a few units to move the needle.) Acer has apparently taken the worldwide lead in consumer notebooks (in terms of units) in Q3 of 2008, edging out HP with 5.04M units (vs. HP’s 4.85M units.) With netbook prices often in the range of $300 to 500, this sure sounds like price erosion to me in the notebook category.

In a previous post, I wrote about the Acer Aspire One Netbook that my wife is using. She does let me use it once in while, so I have actually gotten some stick time on it. My assessment remains largely the same: this is a great little PC for its intended purpose (web usage, email and light text editing). Sometimes it is the little things that can make a big difference: I find myself reaching for the Acer because it boots from a deadstart in under 24 seconds. It makes my WindowsXP and Vista machines seem like slow, plodding dinosaurs. My car starts in a few seconds, so why can’t my PC be instant on?

After about 6 weeks of having the computer, I still give it high marks. The keyboard is slightly cramped but quite usable. I wouldn’t want to type on anything smaller and I do appreciate it when I switch back to a full size keyboard. The touchpad sucks but that doesn’t surprise — I think all touchpads suck, so I am not an unbiased observer. I use a small notebook style mouse whenever possible. The right/left “mouse” keys for the touchpad are placed in a non-standard position, which causes some user complaints. I finally figured out that FN – F7 turns the dang thing off, so I don’t bump it while I am typing.

The Linux OS has turned out to be sturdy and reliable but difficult to adapt. The GUI that layered on top of Linux does a good job as far as it goes. After that, I find myself resorting to the Linux command line to get things done. This is acceptable for me but puts futzing around with the system out of reach for many users. If you don’t speak Linux, then your ability to adapt this machine is limited. But for its intended use, you shouldn’t need to mess with it. So there you go….works well for the intended use but be careful beyond that.

And did I mention it BOOTS FAST?

Got Spam?

How’s your email inbox doing these days? Spamhaus says that spam (also called Unsolicited Commercial Email or UCE) makes up 90% of the email sent in most parts of the world. Since Spamhaus is in the business of providing anti-spam services, it might have a tendency to overestimate the amount of spam.

I have several email accounts for various purposes. One of these is a “junk” account on yahoo that I use for most online purchases and registering at questionable web sites. Examining that inbox, I see 97 messages in the inbox and 647 messages places in the spam folder by Yahoo’s spam filter. Of the 97 messages in the inbox, about half of those are really spam. Another 31 spam messages were sent to a “disposable email address” that I had used at one time. Adding that up, that is a total of 727 spam messages out of 775, which corresponds to 94% spam. Now this is probably a pessimistic measure as this email account is more likely to attract spam and has relatively low legitimate email usage. Still, it is quite amazing how much junk mail it accumulates.

My “real” email accounts have much less spam in them, but it is more difficult to tell the actual percentage. I don’t know for sure what anti-spam measures my ISP uses. On my end, I use Thunderbird’s junk mail controls which seems to catch the majority of the spam. There are quite a few methods available for reducing spam.

The root cause of this is that the internet email protocols were designed with an inherent trust of all users. All of the header information that indicates who sent the email can be easily spoofed, so there is very little accountability in the system. I doubt that the early email inventors anticipated the flood of viagra messages that would occur decades later. This is a classic example of unintended consequences of a new technology. (See Tom Van Vleck’s The History of Electronic Mail for more information.)

So now we spend our time and energy filtering and deleting this nuisance. Even more disturbing are the phishing scams that are showing up in my inbox. There are some very credible fake emails supposedly from major banks and financial institutions that try to get you to log into a fake web page and share your personal account information. Watch out for these!

Various solutions have been proposed to solve the spam problem. Sometimes I think capital punishment might be the answer, but I am not quite ready to propose that……yet. Stay tuned for further updates 🙂

How’s your inbox doing?

Sweet Little Acer Aspire One PC

My spouse’s notebook computer died a few weeks ago, about 1 year after the 1 year warranty expired. This was not very satisfying. I also had my notebook PC die this past year, so it is starting to look like notebooks are disposal devices. Funny, my desktop PCs just keep on going year after year without a problem. This probably has something to do with the abuse that notebooks get being carried around from place to place.

So if we are going to end up replacing these things every few years, I got interested in lowering the cost. There are a number of compact netbooks that typically run Linux on the Intel Atom and use a solid state drive (no spinning hard disk). We settled on the Acer Aspire One, which is $329 from Amazon (free shipping). This computer has a 1.6GHz Atom N270 Processor, 8GB solid state drive, 512MB DDR2 SDRAM, 802.11b/g, Ethernet, three USB 2.0, VGA output, 1.3 megapixel camera, SDHC and multi-format media readers. I popped an 8GB SDRAM card into the expansion slot and it now has 16 GB. It uses the Linux LinpusLite operating system. (Some netbook models are going with WindowsXP, but I think these minimalist machines are better off with the small footprint of Linux.) The only thing I wish it had was a good-old dialup modem for those rare times when you are stuck without a decent wireless connection. (I’d trade that for the VGA display output.)

It comes ready to run with Linux and the key applications already loaded. For web browsing (Firefox), email (Acer Email) and writing (OpenOffice), it is ready to go. I did decide to load Thunderbird for email (instead of the supplied Acer Email application). This machine is configured like an appliance with not much thought of how the user will add applications. However, a little fiddling around on the web and the use of my (cough) extensive (cough) knowledge of Unix commands got Thunderbird loaded.

So far, this computer has exceeded our expectations. It is really compact, has a great display and is easy to use. What it does, it does well. However, it is NOT a full-size, full-featured notebook computer. For the intended use of internet communications, email, web, basic document creation, it works great. I am hoping that the simple design, with no hard drive, with also last a little longer. Did I mention that this thing boots fast? Go, Linux.

I can’t get it out of my wife’s hands. Trust me, I’ve tried.

Followup Oct 11: I’ve noticed that the netbook product category continues to be dynamic with new products being introduced all of the time. Check out the latest offerings from Acer, Asus, Dell, Lenovo, MSI, etc. before making a purchase.

Ernie Gets a Linux Upgrade

One of my old PCs sitting in the basement had Windows 98 on it. The computer was named Ernie by my daughter many years ago. (The taller computer we had at the time received the name Bert, as in Bert and Ernie from Sesame Street.) The OS seemed to be dieing a slow death as it experienced the blue screen of death on a regular basis. I suspected that the hardware was OK and the software was suffering from entropy. It seemed wrong to re-install Win98 in the year 2008, so I considered other alternatives.

For quite some time, I have been wanting to bring up a Linux machine. Why? Bragging rights, I suppose. Feed the inner geek. Real men run Linux, you know. (Masochists run Windows and wimps run Macs….just kidding.) I was also curious about how friendly and useful the OS would be. The Linux folklore also claims that it will run on anemic PCs without any problem. (I definitely didn’t want to install Vista on this old PC.) Back a few decades, I spent quite a bit of time on HP Unix computers and I used to be able to grep with the best of them. More recently our herd of computers have been running operating systems from Microsoft.

It seems that the Ubuntu release of Linux was getting positive reviews, so I chose it as the upgrade for Ernie. I downloaded the latest release and created an install CD. This first attempt to install linux failed, apparently because the PC only has about 200 Megs of memory. The download page said to use the “alternate” version of the release to deal with limited memory. I downloaded that version and the install progressed quite nicely.

During the install process, the software tried to find a network connection, which was unplugged at the time so it told me I could deal with that later. After the install, the system rebooted and ran just fine. The graphical user interface was familiar enough that I could just start using it without referring to the documentation. (We don’t need no stinkin’ manual.)

At this point, I am feeling quite confident, so I connected up the network (Ethernet to DSL at our house). The computer didn’t see the network and I could not find any way to reconfigure it. At this point, I broke down and checked the documentation, expecting to find a friendly little section for people that didn’t have the network plugged in during the installation. No such luck. Eventually, I gave up and re-installed the entire OS with the ethernet cable connected. Although that seems a bit extreme, it did take care of the problem.

Here I am, writing this blog post using Ernie with a new set of brains. (Ernie, not me.) Good old Firefox was automatically installed and is ready to go without any additional effort. Similarly, the OpenOffice suite is installed as part of the Ubuntu release. Not bad, not bad at all.

As described, I did have a few bumps in the road on the installation but nothing too dramatic. My experience with various versions of Windows is not any better. The machine does seem to run kind of slow, in terms of loading applications and responding to GUI changes. I suspect this is due to the limited PC memory. It probably runs about as fast as the Win98, though. I was just expecting better from lean-and-mean linux.

Too Much Data

Disclaimer: I am a little ticked off that my digital scanner (radio receiver, not a graphics scanner) decided to toss its cookies today and lose all of its programmed data. The day before, my Yaesu FT-8900 got amnesia, losing all of its channels. (It seems to not appreciate the voltage dip when the car engine starts.) This reminds me of when iTunes discarded my podcasts about 3 weeks ago. Which reminds me of when my computer hard drive failed, putting my entire digital presence into the bit bucket.

I had always resisted using software to program my radios. When our public service agencies switched to 800 MHz trunked digital, I didn’t have a choice anymore for the scanner. The complexity of that system requires a software program to manage the channels. I also tried to avoid using software to program my amateur transceivers. (Old Guy Talk: Back in the old days, we only had a band switch and one big VFO knob to turn and that was plenty good enough.) Slowly, but surely, the huge number of memories and features available have teased me into buying the software to keep track of it all. I don’t mind paying for the software…typically, the programs are a bargain.

I do object to the time it takes to manage this stuff. You might think that there would be a standard file format that stores my favorite frequencies, transmit offset, CTCSS tone and channel labels so that I don’t have to enter them every time. No, that would make too much sense.

What other cute little electronic devices require their own database? I already mentioned iTunes and MP3 players, where the songs are just bits on a computer. (Not your old 8-track tapes anymore, is it?) My GPS receiver has its own set of maps that demand to be cared for and fed to keep the little device happy and useful. (The other day, a bit in the GPS got set that told it to ignore the maps that were loaded. I could see that the maps were there but the GPS was apparently not using them. A master reset and reload eventually cured the problem.) The GPS also makes use of my favorite set of waypoints that I maintain…carefully stored on The Hard Drive, waiting for the next disk crash.

Oh, and don’t forget digital cameras….they are the Masters of Data Creation. One click of the camera can generate a file with a million or two bytes. A day of photography can fill up a few gigs of storage with no effort at all. All of these precious photos need to be stored somewhere to be preserved for posterity. (Should I put posterity on The Hard Drive?)

There is just too much data in my life, and the trend line is increasing. Keep in mind that this data is the kind that you never really see. You can’t see files on a hard drive, you can’t see mp3 files on an iPod, you can’t see the bits programmed into my scanner. Oh sure, you can see something that pretends to represent the actual data….The Hard Drive lets you display a Word document on your screen and print it out. It is supposed to be the same as the file on The Hard Drive, but that is just an approximation….or maybe an illusion. Another reason bits are so hard to manage….they are invisible.

Back to the scanner…I had the configuration file on The Hard Drive (and backed up via Carbonite, just in case.) The Win96 software that programs the RadShack PRO-96 scanner was a victim of the recent hard drive failure, so I had to reinstall it. The program refused to run until I found the magic registration key that proves I paid for the software. No problem…found that on The Hard Drive as well and off we go. Then, the PC had trouble talking to the scanner via the COM port, mostly because there is no COM port on the PC. That is, I needed to use a USB-to-Serial Port converter. (Insert another poorly documented device of questionable origin.) Can we just have USB ports on all data-hungry electronic devices? After much fiddling around, I got the scanner to load all of the data.

Any one of these things is not that big of a deal. I can deal with one or two special programs and cables. But after being surrounded by these self-centered little devices that don’t play nicely, it really starts to wear you down. Clearly, the amount of data is going to continue to increase and more devices are going to take advantage of it. So don’t count on the problem getting any simpler. Ever.

So what’s the solution?

  • Electronic devices should use standard data formats that share easily from device to device. They shouldn’t insist on their own native format. Sharing data is good.
  • These devices should use standard interfaces and memory cards so that moving data around is trivial. Get rid of the proprietary cables.
  • The software that handles the data should be designed and tested for maximum usability using established human factors methods. Every feature should work with minimal effort for the end user.
  • Last but Most Important: these devices shouldn’t ever lose their memory. Bad, bad, bad, bad.

There, I feel much better now.

Visit to Akihabara

Every once in a while, I pass through Tokyo, Japan on business travel. When the schedule permits, I make a trip over to Akihabara (AKA “Electric Town”), the center of electronic and computer gadgets in Tokyo. This place is amazing, offering everything from resistors to wide-screen televisions (and, yes, ham radio equipment). The only thing I can compare it to in the US is Fry’s Electronics….but it it more like a multi-vendor Fry’s that spans many blocks. They have small shops that are very specialized…..such as focusing only on transformers or coaxial cable. It is amazing what you can find there.

Last weekend, I was staying in Shinjuku and made a quick trip over to Akihabara. Assuming you know the basics of the JR train system, it is an easy ride from Shinjuku Station (or Tokyo Station) to Akihabara. (Akihabara has its own train stop.) For ham radio equipment, you have to aware that the Japanese version of the radio may be set up differently than the radio sold in your home country. For example, the 2M band in Japan goes from 144 to 146 MHz, so VHF radios sold there will usually be enabled for transmit in that range. Just as important, with the weak dollar there are not really any great bargains for ham gear in Tokyo. You can probably buy the right radio in the US for the same or less cost.

What I look for in Japan are radio accessories that are hard to find in the US. It seems that Japan is the land of gadgets, so there’s always some little antenna, adaptor or other gizmo that catches my eye. I guess I am saying that I go to Akihabara for the experience and the occasional gadget purchase. Not a bad way to spend a Saturday for an electrical engineer geek.

My big purchase for the weekend is a $5 screwdriver that has a continuity tester and a AC voltage sensor built into it…typical Akihabara gadget that I could not pass up. More information on Akihabara is shown here and here.

My Hard Drive Would Never Fail

I powered up my PC a few days ago and it gave me a very blank stare. Actually, it had one small message for me: operating system missing. Hmmm, that did not sound too good.

I investigated further…booted the computer from a CD. Did “chkdsk” which told me my hard drive was Missing in Action.Lucky for me, I had just backed up the My Documents folder a few days earlier, so in theory I had all of the important stuff saved away. After messing around with the computer for a while, I came to the conclusion that I would have to format the hard drive and reload everything. Even then, I wasn’t sure the format was going to work….maybe the hard drive was totally dead.

It turned out the format worked and I spent the next couple of days reloading Windows XP (thank goodness I found the recovery CD that shipped with the computer). Then I reloaded the My Documents folder without any trouble. The thing I miss the most right now is my email address book, which disappeared. I have an older copy backed up somewhere so I’ll try to reload that one. In the future, I’ll add the address book to the backup strategy.

I count myself lucky that I had all the docs backed up but it is still a major pain to reload Windows XP and all of the applications. It will be weeks before I get it all done.

FCC Reports on Broadband

From the ARRL web page:

FCC Releases Broadband Report (Nov 5, 2007) — The FCC has released their latest report summarizing the state of broadband in the US as of December 2006. It shows that in December 2006, Internet-access BPL has increased slightly over December 2005, but also shows that it has been decreasing slightly from a peak that occurred sometime around mid-2006. According to the report, BPL ended up with a deployment total of 0.006 percent of the total broadband lines in the US, compared to 0.011 percent at the end of December 2005.

OK, let’s just see how BPL is doing in terms of adoption. Here are the number of BPL subscribers listed in the report:

June 2005: 4872
December 2005: 4571
June 2006: 5208
December 2006: 4776

So in the last six months of the study, BPL actually declined in use while the other broadband technologies increased by 17 million. See Slow Death for Broadband Over Powerline.
