This Spewed Out of the Internet #17

Posted on by

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.

CQ WW VHF – Just Another Day of Sporadic-E

Posted on by

You just have to love VHF contesting….hours of boredom punctuated by the excitement of band openings. Unlike HF contests, you never really know what you are going to get in terms of propagation.

So it was with the CQ Worldwide VHF Contest this weekend. It started out really slow on Saturday. I mean really, really, really slow. There were not many local stations on the air, so it was tough sledding on both 2 Meters and 6 Meters. (Yes, the CQ WW VHF Test is two bands only: 2 Meters and 6 Meters…and those are my favorite bands to work anyway.)

Then later in the afternoon, I hear Louisiana stations coming in on 6 Meters. Then the magic sporadic-e clouds shift and I am working the east coast, all the way up into the New England states. Later the propagation shifts to the midwest and it was Wisconsin, Michigan, Indiana, Iowa and Kansas. I was working them as fast as I could and had quite a pileup into DM78 Colorado. The band stayed open till about 9 PM local…just when I thought it was done, another station would come booming in.

Sunday started out slow but during the morning I worked the Pacific northwest on 50 MHz, including several contacts into Canada. This opening was not as strong, but it kept me busy until the afternoon. Then it was picking up everyone I could on 2 Meters. Again, local participation was surprisingly light…not sure what’s up with that.

Band  Mode  QSOs   Pts  Grd
50     CW     1      1    1
50    USB   259    259  112
144    CW     1      2    1
144   USB    14     28    7
Total Both  275    290  121

Score : 35,090

All in all, a great time was had by me.

FCC Adopts Changes to 97.113

Posted on by

The FCC has adopted rule changes to Part 97.113, allowing employees to communicate on behalf of an employer during emergency preparedness drills.

I’ve posted several times about this topic, see EmComm Trouble, Time to Change the Rules,  FCC Moving Ahead on the topic.

The new version of the rules are listed here:

§ 97.113 Prohibited transmissions.  
 
(a) * * *
(3) Communications in which the station licensee or control operator has a pecuniary interest, including communications on behalf of an employer, with the following exceptions:
 
(i) A station licensee or control station operator may participate on behalf of an employer in an emergency preparedness or disaster readiness test or drill, limited to the duration and scope of such test or drill, and operational testing immediately prior to such test or drill. Tests or drills that are not government-sponsored are limited to a total time of one hour per week; except that no more than twice in any calendar year, they may be conducted for a period not to exceed 72 hours.
 
(ii) An amateur operator may notify other amateur operators of the availability for sale or trade of apparatus normally used in an amateur station, provided that such activity is not conducted on a regular basis.
 
(iii) A control operator may accept compensation as an incident of a teaching position during periods of time when an amateur station is used by that teacher as a part of classroom instruction at an educational institution.
 
(iv) The control operator of a club station may accept compensation for the periods of time when the station is transmitting telegraphy practice or information bulletins, provided that the station transmits such telegraphy practice and bulletins for at least 40 hours per week; schedules operations on at least six amateur service MF and HF bands using reasonable measures to maximize coverage; where the schedule of normal operating times and frequencies is published at least 30 days in advance of the actual transmissions; and where the control operator does not accept any direct or indirect compensation for any other service as a control operator.

 

The FCC does allow for drills that are not government sponsored, but did include some time limits on these exercises. At first glance, these rules look reasonable to me. What do you think?

2010 Colorado 14er Event

Posted on by

The Colorado 14er Event will be held on August 8 this year. This is the premier mountaintopping event for amateur radio. The basic idea is to have fun making ham radio contacts from the 14,000 foot peaks in Colorado.

Actually, we’ve started to see some of the 14,000 ft peaks in California on the air, too! Very cool. Rumor has it that some of the New Mexico hams might be active on the highest summits in that state (none are above 14,000 feet though). I don’t know whether the Kansas folks are going to brave the extreme conditions on Mount Sunflower this year or not. (That’s the highest spot in Kansas.)

Some of these stations will be on HF, activating Summits On The Air (SOTA) peaks.

For more information see:

The 14er Event Web Site

The Ham14er Yahoo group

I hope to work you during the event.

Here Come the Chinese Radios

Posted on by

I happened to be in Hong Kong on business and wandered around the Kowloon area looking for electronic gadgets. I started noticing several different models of handheld transceivers, some of them marketed as ham radios. I counted at least 10 different brands of equipment, all made in China.

A Wouxun radio caught my eye, as I recalled some discussion about these radios being available at Dayton for a very reasonable price. I took a look at it and was pleased with the look of the radio. The price was right, too…less than $100 US.

This Wouxun KG-UVD1P is a very capable dualband 146 MHz/ 446 MHz radio. The whole idea of such a low cost radio had me hooked…I basically wanted to know if the radio was any good….so I bought one. (I have to confess that I forgot to negotiate a lower price which is common in these Hong Kong shops.)

I took the radio home and have been playing with it. So far, I am very impressed. I’d like to find some time to check out the performance with my test equipment, but that will have to wait. I’ve also noticed that there are some reviews and mentions of this rig on the internet: eham.net, W2LJ,  Wouxun web site and hamradioshop.it .   The N9EWO has quite a bit of detailed information about the radio on his website. He points out that this radio is not really a full dualband transceiver…the VHF and UHF receiver share some circuitry such that you can’t actually receive two signals simultaneously.

So here come the Chinese radios. Not a big surprise as many low cost electronic devices are manufactured in China. However, the Big Three (Yaesu, Kenwood and Icom) are Japanese companies and as far as I can tell have kept most of their manufacturing in Japan.

Amateur radio transceivers are a mature technology, so expect to see more of these Chinese radios showing up in the US.

Your Mileage May Vary, All Disclaimers Apply.

Update 10 July 2010 : there is a Yahoo group for discussing the wouxun radios.

Update 18 July 2010: Wouxun US website: http://www.wouxun.us/

This Spewed Out of the Internet #16

Posted on by

Here’s a few things flying by on the internetwebz. 

K3NG announces a new online logging service with some odd characteristics. Quite funny, so check it out.

Now this is really interesting: Mark AF6IM did a parachute jump during the June VHF QSO party and made some contacts during his descent. The ARRL rules do not allow aeronautical mobile contacts for the contest but apparently they consider parachuting to be in a different class. (I call it “jumping out of a perfectly good airplane for no reason” 🙂  ) Read the Southgate ARC article for more information. It seems that ham radio plus skydiving is turning into a niche sport (see parachutemobile.org ).  I like this kind of crossover activity for amateur radio!

The technical powerhouse nation of France has decided that D-STAR is illegal in that country. See the article on the Southgate Amateur Radio Club site.  Quoting from that site:

A report on the French digital ham radio website (DR@F) says that the regulator, the ARCEP, has said the D-STAR protocol specifications could allow ham-radio operators to connect their station to Internet and that is prohibited.

 K3NG has something to say about D-STAR: Announcing D-STAR Illegal in the US and Now France.

The FCC recently got the idea that they should update the General Mobile Radio Service rules. They are proposing to remove the licensing requirements for GMRS along with some other changes. This looks to me like the last nail in the coffin for a useful GMRS service. The FCC already screwed up by intermingling Family Radio Service channels with GMRS channels. (An unlicensed service on the same frequencies as a licensed service? Brilliant.) So now the world is filled with these “bubble pack” FRS/GMRS radios used by unlicensed and largely radio-clueless users. I am tempted to file comments on the NPRM but it feels like the ship already sailed.

The new Apple iPhone apparently has a problem with its antenna design. Something about leaving the antenna elements exposed means that the user can detune/obstruck the antenna by holding it in his hand. Gee, who would have thought of that (other than thousands of qualified RF engineers worldwide)?  No worries, it now appears that Apple is looking for a few good antenna engineers. Good idea.

And the rumors pursist that the iPhone is coming to other US mobile phone providers (besides AT&T). USA Today says the iPhone will be on Verizon next January. This seems inevitable to me, but I am not sure I care. The Android phones are coming on strong with a more open system. It’s even possible that my life will continue to be fullfilling without carrying a smart phone around 24/7. Maybe.

ARRL Field Day in Monument

Posted on by

This weekend is the ARRL Field Day, the major ham radio operating event in North America. Here in Monument, the Pikes Peak Radio Amateur Association and the Tri-Lakes Monument Fire Radio Association will operate from TLMF Station 1. Details are on the PPRAA web site.

The “Get On the Air” station is perfect for new hams that want to try out HF. Everyone is welcome to stop by, operate, chat or just observe.

QRP Results in the January VHF Contest

Posted on by

The July issue of QST arrived in the mail recently with an article on the January VHF Sweepstakes results. It always takes about 6 months to have the scores show up in QST, so some people make it a point to share their scores via email and figure out who won. I just submit my log and then forget about it until the scores get published, which means I have usually completely forgotten about the contest by then. It can make for a nice surprise when the article gets published.

This year I reverted back to my “hike up a local mountain and operate QRP” operating style. The past few years I have been more of a slacker, operating from the comfort of our cabin up in the mountains. The backpack portable approach is a lot of fun but does limit how many hours I operate and therefore keeps the score on the low side. I am not about to freeze my behind by spending the night on the mountain in January. It does make for a fun hike, often requiring snowshoes to make it up to the summit (but not this year). My soapbox comments, including a few photos, are on the ARRL web site.

So I opened QST and found that I absolutely dominated the Rocky Mountain Division with my 741 points :-). Here’s the list of Single-Operator Portable scores for the entire contest:

# Call Score QSOs Mult Class Section
1 N3YMS 32,184 260 72 Q DE
2 N8XA 6,864 123 48 Q OH
3 W9SZ 2,268 38 28 Q IL
4 WB2AMU 1,518 63 22 Q NLI
5 K9TMS 1,420 46 20 Q EB
6 K0NR 741 39 13 Q CO
7 W0UC 380 19 10 Q MN
8 N0HJZ 192 12 4 Q MN
9 KC8KSK 138 17 6 Q NC
10 N0JK 80 10 8 Q KS
11 K1EXE 60 12 5 Q VT
12 VA3RKM 56 9 4 Q ON
13 K9PY 50 8 5 Q AZ
14 KD7WPJ 48 6 6 Q UT
15 KB2AYU 45 9 3 Q EPA
16 WA1LEI 39 13 3 Q CT
17 W0DJM 35 5 5 Q MN
18 K7RLL 15 4 3 Q VA
19 W6MDH 12 3 3 Q EB
20 N3RG 8 1 1 Q SNJ
21 WA3WUL 8 1 1 Q SNJ
22 W6CT 4 2 2 Q SCV
23 K2ULR 1 1 1 Q GA

The competition in this category is a mix of activity ranging from very serious efforts (e.g., N3YMS with over 32,000 points) to people that just make a handful of contacts. It turns out I placed 6th overall. I didn’t enter the contest to win, but I have to admit it is nice to know there is a category where the Peanut-Whistle Stations don’t get swamped out by the Big Guns.

If you want to try something different, give VHF QRP a try in one of the contests.

This Spewed Out of the Internet #15

Posted on by

It’s time to do one of those miscellaneous collections of drivel that spews forth from the interwebnet pipes. Some of this might even be important!

Some upcoming events: ARRL June VHF QSO Party and the Colorado FM Sprint, on the weekend of June 12th. The FM Sprint runs concurrently with the ARRL contest but only on Sunday afternoon. This is a good chance to get on the air with very basic equipment and have some fun.

The ARRL Field Day is coming up on June 26th and 27th. This is arguably the biggest on-the-air amateur radio event in North America.

I was playing around with setting up an SMS text messaging system for callsign lookup. The idea is that you send a text message (containing an amateur call sign) with your mobile phone and get the FCC or QRZ info back. In the meantime, I found that this problem has been solved by Callsign By Text. Very nice, check it out.

Female radio amateurs should check out Chick Factor International. It looks like a fun group.

I picked up a DV Access Point (DVAP) for D-STAR. This is a neat little device that provides flea-powered D-STAR access on 2 Meters by plugging it into a PC with internet connection. The South Yorkshire Repeater Group has a good description of the product. So far, this thing works really well.

By the way, the South Yorkshire group has a really good web site…interesting and timely information. Although they are in the UK, I find it relevant to US ham radio activity, too.

The Technician Class License question pool will be updated as of July 1, 2010. Our next Tech Class in Monument will be in October, so we’ll be updating the classroom material before teaching that class. It is clear that more technical content is being added to the question pool, which I think is a good thing. See KB6NU’s posting on the topic.

From The Complete Waste of Time Department, the FCC once again dismissed a petition from K9STH to change the amateur radio station identification requirements. Look, the FCC doesn’t see a problem here (and neither do I) so save yourself the trouble.

The FCC is seeking comments on the proposed new rules concerning emergency communications.  I took the time to file a short comment, basically saying that the FCC is on the right track but they should remove the reference to “government-sponsored drills”. Any legitimate emergency communications drill should be included, regardless of who sponsors it. The ARRL made similar but more detailed comments.

Update on the IC-9100

Posted on by

Ham radio VHF enthusiasts have been patiently waiting for the ICOM IC-9100. This HF/VHF/UHF/Satellites covers most or all of the popular amateur bands. Recently, ICOM has posted the specs and brochure on its web site.

The rig has dual receivers that allow monitoring two bands at once and it is set up for full-duplex on satellites. The built-in antenna tuner covers HF and 50 MHz. Operating on 1.2 GHz requires an optional module.

There is an optional DV (D-STAR) option that works on 10M, 6M, 2M, 70 cm and 1.2 GHz. This is the first combo HF+VHF+UHF rig that has DV available.

The 100 Watt output power all the way up to 50 MHz and 144 MHz is a real plus and 75 Watts on 430 MHz is not bad either. The 1.2 GHz option would be nice, too. This would be a great radio for portable VHF contesting. Oh, and I guess it works HF, too. 🙂

So everyone was expecting a big ICOM announcement at the Dayton Hamvention. Based on the reports I heard via the D-STAR system in Dayton, one unit was shown “under glass” so attendees could look but not touch. Also, a number of people have reported that the ICOM booth staff are saying that the 9100 will be available later this year (fall timeframe?) at a price of ~$US 4000.

Ouch. Most observers see that as a bit too expensive. I’ll withhold judgment until it is really in stock at a dealer with a real price.

SWR and Return Loss – There’s an Ap for That

Posted on by

For the RF/microwave enthusiasts out there, you may recall the old HP Reflectometer Calculator that does conversions between SWR, Return Loss and calculated mismatch uncertainty.

Well, fast forward to the 21st century and this same functionality can be found in an iPhone ap. Agilent Technologies has a free ap available on iTunes that does these calculations and some other things like decibel conversions.

Check it out at here or just search for microwave calculator on iTunes.

Bob’s Rules for A Fun Radio Club

Posted on by

The other night, I attended one of those unfortunate, but all too common dysfunctional radio club meetings. (The name of the club will remain confidential.) You have probably been to one of these sessions where the leadership of the club is frustrated because they feel like only a few of the members are doing all of the work. The other folks may come to the meeting but are reluctant to sign up for anything.

The topic of discussion happened to be Field Day. The plans in place were not coming together and the leadership was getting frustrated. My point of view was quite simple: if no one wants to help with Field Day, then let’s not have Field Day. Heck, this radio club stuff is supposed to be fun. If we are trying to make activities happen that people don’t want to support, then we are probably off in the weeds.

This caused some of the folks to raise their hands and say “yes, of course we should do Field Day and this is how I can help.” So things are probably on track for now. Maybe.

This situation is not unique…most clubs (of any kind) have the core group that does most of the work and the secondary group that does much less. Sometimes the players change depending on changing circumstances such as family and work obligations, but the structure tends to remain.

I came up with a couple of simple rules to avoid frustration in this kind of situation:

  1. Don’t volunteer to do anything that you aren’t personally motivated to take on. If you aren’t doing it because you truly want do, then you’ll end up resentful if other folks aren’t “doing their fair share.” It’s a volunteer organization, after all.
  2. Don’t expect others to sign up for volunteer work because you think it is important. Their priorities might be different and it is totally their decision (see Rule 1).
  3. Lead, Follow or Get Out of the Way. If you want to make something happen, get out in front and lead. If you don’t want to lead, then follow. Commit your own time to making it happen (see Rule #2). If you can’t lead or follow, then stay out of the way.

I get enough of this “gotta do it” stuff at work. Ham radio should be fun.

What do you think?

AM, FM, WX and 2-Way Radio

Posted on by

A few weeks ago, I woke up to find that the power was off at my house. It so happens that most of the fun electronic stuff in the house doesn’t actually work when the power is out. The most critical thing is that the freaking internet didn’t work. Huh?

I remembered that I had purchased one of those whizzy emergency radios that has a hand-crank generator built into it. After I fumbled around and found it stuffed away in a closet, I gave it a crank and the radio receiver came alive! Wow, instant communications without batteries or AC power.

I got to thinking that we should have one of these radios at the cabin up in the mountains. After all, the power goes out there even more often.

Searching around Amazon.com and a few other sites, I discovered that the Midland XT-511 Base Camp radio has a hand-crank radio that includes AM broadcast, FM broadcast, Weather receive and, yes, a GMRS 2-way radio. OK, it doesn’t work on the ham bands but the FRS and GMRS frequencies might be useful when things go dark.

It arrived the other day and, so far, I am very pleased with it. It is a consumer grade piece of radio gear but it seems to perform well. I tuned around the AM, FM and Weather bands, clearly receiving the stations that I would expect to hear. The GMRS radio seems to work OK but the transmit audio was a little mushy.

The radio can operate off of the internal rechargeable batteries or standard AA alkaline batteries…quite flexible, I’d say.

The radio costs around $56 from Amazon.com.

Results from the Second Technician Class

Posted on by

We completed our second attempt at the Technician License Class. The format we are using is two all day Saturday sessions, supplemented by self-study using the Gordon West book. We had 14 people take the Technician exam (Element 2), with 13 passing (93% pass rate).  We had 4 Boy Scouts in the group and they all passed. (Their troop is getting quite a few Scouts with licenses and they are having a blast with it on camp outs.)

The 2-day formula seems to be working, so we’ll do it again in the fall. Summer seems like a good time to lay low and we will need to rework the material due to the new question pool for the Tech exam. At first glance, it looks like the new question pool is a little more difficult as it includes more advanced technical topics.

The next Technician Class will be held in the fall, tentatively scheduled for October 16 and 23.

This Spewed Out of the Internet #14

Posted on by

Happy Easter!

A few posts back, I wrote about podcasts worth listening to. I want to draw your attention to two additional ham radio podcasts:

  • Teen Radio Journey by Paul KC9QYB, available on iTunes or at http://www.teenradiojourney.com/ This podcast is intended for teenagers, so I am definitely outside of that target audience. I mention it here because anything that involves youth in amateur radio is a good thing.

I just stumbled onto the radio contesting site radio-sport.net. It has probably been there for decades and I am late to the party. It is worth checking out if you are into contesting.

I went through the entire day without thinking about buying an iPad. To quote Joey from Friends, “its all a moo point.” Even if you do want an iPad, why would you buy the first implementation, given Apple’s track record? There will be a better one coming along soon enough. Take a look at the Fake Steve Jobs blog.

The high-powered think tank at the Fi-Ni Report has published some brilliant work:

  • The investigative team has uncovered yet another scandal in the radio sport world, this time relating to the Poisson d’Avril Contest
  • AM (Ancient Modulation) is getting a strong endorsement from the CQWW Contest, pushing aside that sissy SSB modulation
