Golf November Tango

Posted on by

when-all-else-fails-logoAmateur radio has a deep tradition of providing emergency communications during all kinds of disasters. Of course, some emergencies are more urgent and serious than others.

The Golf November Tango frequency is an important frequency to always have programmed into your radio. Established as 146.55 MHz ( FM simplex, no CTCSS), the GNT Frequency is the critical logistics channel for certain types of incidents (to use ICS terminology).

This all started when three ham radio operators found themselves stranded on the shore of Lake Michigan. Well, actually they were not so much stranded as just sitting there watching the waves roll in. Without warning, they found themselves getting thirsty without any liquid refreshment in sight. Rather than make the long, treacherous walk back to the beach house, a 2M FM transceiver was employed to make the critical call. Fortunately, the wives of these dehydrated amateurs were also FCC licensed amateur radio operators monitoring the designated GNT frequency.

Without delay, communication was established with the beach house and the critical resupply of Gin and Tonic was delivered. There was some thought that the guys on the beach were just being lazy, but the requested GNTs were quickly dispatched anyway.

After that incident, 146.55 MHz was established as the GNT Frequency for all of North America.

Like they say, When All Else Fails.

EmComm Trouble From the FCC

Posted on by

fcc-1There has been quite a ruckus about the FCC and Part 97.113 concerning emergency communications but I have been taking a wait and see attitude about it.  These FCC Rules say:  No amateur station shall transmit communications in which the station licensee or control operator has a pecuniary interest, including communications on behalf of an employer.

The question on the table is whether this prohibition strictly applies to employees of a public safety organization. For example, is it a violation of the rules for a firefighter or hospital employee to use ham radio as part of a emergency communications practice exercise? Apparently, the answer is yes.

Read this posting on the N5FDL Blog for more details, including some correspondence with the FCC. The ARRL offered this explanation in the September issue of QST. This article reports that W0WLS is withdrawing from ham radio emcomm work after getting a letter from the FCC’s Laura Smith.

The K3NG Report says that The FCC is Throwing the Baby Out With the Bathwater.  I agree.

If you are involved with emergency communciations, you should make sure you understand this latest development.

Mountains, Radios and the Goats

Posted on by

Steve (WG0AT) has done it again with a great video of the Colorado 14er Event. Take a look at the saga of two guys and two goats scrambling their way to the top of Mount Humboldt (with the exclusive GoatCam technology). This new adventure features Peanut and Rooster, the brain power behind the Old Goats Hiking Team. This video captures the spirit of the 14er event, the premier mountaintop radio event.

Colorado QSO Party

Posted on by

colorado-flagThe Colorado QSO Party, sponsored by the Pikes Peak Radio Amateur Association, will be held this Saturday Sept 6th. This is a great opportunity to get on the air and have some fun on the HF, VHF and UHF bands. There have been some changes to the rules this year, so be sure to review the complete rules.

Amateurs outside of the state of Colorado work as many Colorado stations as possible. Colorado stations work everyone. The emphasis is on activating counties, so if you might consider operating portable or mobile to support this goal.

The contest period for 2009 is from 1200 UTC 5 Sept. 2009 until 0400 UTC 6 Sept 2009 (6AM to 10PM MDT).

I plan to operate from our cabin in Park County, near Trout Creek Pass.

This Spewed Out of the Internet #8

Posted on by

0511-0701-3118-0930I am trying out a new twitter ap called DestroyTwitter. There are many to choose from, so as I reloaded my PC I decided to give this one a try. So far it seems to be good, which means compact, not too fancy and easy-to-use.

John C. Dvorak wrote that Twitter is the New CB Radio. I think he is right. My enthusiasm for twitter drops about 1 dB per week.

The VHF/UHF crowd is excited about the new ICOM IC-9100 that was shown recently at a Japanese ham radio show. This is basically an HF + 6 Meters + 2 Meters + 70 cm transceiver set up for satellite and (optional) D-STAR. Kind of does everything.

I am very much in favor of a Cash for Clunkers program for amateur radio gear and computer gear more than 5 years old. It seems like the gubment is handing out money to everyone else (without much logic applied), so why can’t we get a piece of that?

Interesting piece from the ARRL about power line companies and their responsibilities concerning radiated interference. Despite all of the concern about Broadband Over Powerline messing up the ham bands, there are far more incidents of good old power line noise causing trouble for ham radio operators. I have been involved in several of these cases and it is generally a real mess….especially if the utility is incompetent.

AMSAT has rejiggered its Suitsat program to fly without the spacesuit. I always wondered why they needed a spacesuit to make this work anyway. It turns out they don’t. The new suitless name is ARISSat-1.

There has been plenty of bickering on the AMSAT-bb email list as various people have complained about this project or that project AMSAT is pursuing. For some reason Suitsat-2 has become a target for complaints. My philosophy? Anything that involves amateur radio in space that works is OK by me.

I continue to play around with D-STAR now that the repeater is up and running in Monument. I was sitting there last night fiddling with the radio when VK2LOB from Sydney, Australia comes on the frequency looking to demonstrate D-STAR. We had a nice, short chat — what a pleasant surprise!

Pikes Peak Operation – 2009 Colorado 14er Event

Posted on by

We rounded up the usual collection of suspects to operate from Pikes Peak in the Colorado 14er Event. Our crew included me, Joyce K0JJW, Ken WA6TTY, Stephen KZ0Q, Steve KD0BIM, Stan WA0Z and Matt KC0LBA.

Since Pikes is a “drive up” mountain in an event where most radio operators hike in, we tried to compensate by covering as many bands as possible. We had 4 stations on the air:

  • 2M FM
  • 50 MHz (mostly SSB, some FM)
  • 222 MHz FM, 440 MHz FM
  • HF (20 Meters – Mostly SSB, some CW)
Antenna tear down: Bob K0NR, Stephen KZ0Q and Steve KD0BIM
Antenna tear down: Bob K0NR, Stephen KZ0Q and Steve KD0BIM

This had to be the best weather for the event in years, with no one reporting being chased off the summit by approaching storms. This is odd considering the stormy weather patterns we have seen this year.

Most of the 2M FM contacts used callsign KD0BIM, everything else used the club callsign K0YB.

Summary of Pikes Peak Log:

Band      QSOs    14ers          Comments
146 MHz    83       13    Best DX: K4S Mt Sunflower and N0KQY in Kansas
50 MHz     21        1    Only 14er: KQ6EE on Elbert
222 MHz     3        1    Only 14er: KQ6EE on Elbert
440 MHz     7        3
HF (20M)   17        1    Only 14er: N0B on Humboldt
Total:    131       13


We operated for about 4 hours, averaging about one QSO every 1.8 minutes. Pretty good rate for this event, based on past experience.


We clearly missed some of the 14ers that were on the air. Based on my count, there were 16 summits activated during the event:


Elbert, Massive, Grays, Antero, Torreys, Quandary, Evans, Princeton, Yale, Bross, Pikes, Humboldt, Bierstadt, Redcloud, San Luis, Huron


Thanks to everyone that came out for the event!

0511-0701-3118-0930This is the usual “catch up” posting, when I don’t have a specific topic but try to share some interesting things flying by on the internet.


I came across this article about poor passwords being the biggest computer security problem (as opposed to viruses and worms). OK, maybe so. Using passwords like “password” and “xyzzy” may not be the best approach. (If you recognize “xyzzy”, that says something.) How about we come up with a new approach to computer security that doesn’t require me to have 23 different passwords, all of which need to change every 3 months? And then the security guys get grumpy if we actually write these down.


I had another gosh darn mf  &$%$# meltdown on my notebook computer, but fortunately everything was backed up using Carbonite. Unfortunately, it took 14 days to pull the data back off Carbonite onto my new netbook computer. That download time seems a bit excessive, don’t you think? I don’t know what the problem is with Carbonite but it is not just me..do a little googling binging on “carbonite slow restore” and you’ll find lots of unhappy customers. Or check out the reviews on Amazon.com. I have taken Carbonite off the Bob’s Preferred Vendor List. Don’t use them.


From the Maturing Market Department, MFJ buys Cushcraft amateur antennas. We’ll probably see more of this.


I already mentioned the Colorado 14er Event, which is tomorrow morning (Sunday August 9th). We will have quite a crew on Pikes Peak…including an HF station, most likely on 20 Meters SSB. Look for us around 14.260 MHz with callsign K0YB.


Apparently, RadioShack is in the process of rebranding itself to be simply The Shack, according to Engadget.com.  Interesting development….how much “radio” stuff do they really carry anyway?

Colorado 14er Event – August 9th

I woke up yesterday to the idea that it really is August 1st and that July is now history. I understand how that happens… I just don’t know how it happens so freeking fast!  If August is here, then it is time for the premier mountaintop ham radio event: The Colorado 14er Event.


What is that, you ask? It is ham radio guys having fun in the mountains, where Height Above Average Terrain takes on a new meaning.  


Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Radio operators with 14er climbing experience who plan to climb a 14er should log their name and intended peak at the HAM 14er Yahoo group.


I will be operating from the summit of Pikes Peak with a crew of other ham radio operators, using club callsign K0YB.


Last year we had a California operator (N6IZ) get on (yes, they have mountains there, too) and work one of the Colorado summits (N0B), for the first 14er-to-14er interstate QSO. See the goathiker (WG0AT) video for the full story:


 


We expect to have some California 14ers on the air again this year. Not only that, the K4S team in Kansas is planning to ascend the highest point in the state: Mount Sunflower at 4039 feet !


This is too much fun.

0511-0701-3118-0930Lots of interesting things spewing forth from the internet these days:


Jeff KE9V articulated a compelling vision of web-based (“cloud computing”) ham radio logging. This caused a lively discussion among some readers (read through the comments on Jeff’s blog). I found the idea interesting but I am inherently suspicious  of the notion of  “cloud computing”.  (“I give you all my information and trust that you’ll do the right thing with it.”) As I read through the comments, I realized that what interested me was the idea of having all these logging programs playing well together and with other applications such as Logbook of the World. Right now, this is mostly a pain. That seems to imply we need well-designed standards that define how the software interoperates, whether it exists on my PC or in the cloud.


Jeff also had a great post about narrow-minded thinking. Reminds me of my previous post about Religion and Ham Radio.


The  Fi-Ni Report had a hilarious piece about a ham that puts a small VHF/UHF vertical on top of a 100-foot tower:  Ham Claims New Tower is Not Overcompensating.


On a more serious note, it seems that some folks are concerned that the proliferation of radio communications towers are killing off certain migratory birds. This is the first time I have run across this issue, which surprised me a bit. A little Googling Binging on the web finds quite a few articles about it. It seems that the birds fly into the towers or guy wires, especially at night.


I found this spoof of Apple by The Simpsons on You Tube. Pretty funny….unless you are an Apple Fan Boy.


Scot, K9JY, publically admits to buying an Apple computer. One of my daughters has also turned into a Mac fan. I tell her, “Sure, if you want the silly computer to just work, buy a Mac. If you want to dig in and learn all about configuring networks, troubleshooting software  problems, understanding file formats and becoming a real computer user, then get a PC. If not Windows, then Linux.”


In case you haven’t heard, the 40th Anniversary of the Apollo 11 Moon Landing is coming up on July 20th. There is a really cool site (http://www.wechoosethemoon.org/) that is recreating the events in real time (40 years later). Check it out. What a reminder that we can accomplish amazing things if we commit our hearts and minds to it!  Unfortunately, it is also a reminder that it is easy to sit on our butts for  40 years and not accomplish much in space.

XE1MEX Satellite DXCC

			
			                

                    Posted on   by                                      

					


		 		

			
dxcc-logoDuring this busy Field Day weekend, I received an email from Alex XE1MEX reporting that he has achieved DXCC via Satellite. This is quite an accomplishment since he made most (or all?) of the contacts via LEO satellites. It turns out that I have worked XE1MEX several times on the FM birds from home and from PJ4 (Bonaire) and HR3 (Honduras). Although I have not been on the OSCAR satellites lately, a few years ago it was a major focus of my ham radio activity…resulting in VUCC on Satellite. I made it a point to activate rare grids and countries whenever I could and it was tons of fun!


It is great to hear that Alex achieved his goal of DXCC. I really appreciate that he took the time to thank the hams that helped him get it done by activating the various countries. It brings back memories for me…maybe I should dust off that Arrow II antenna and go find an island to activate!

Summits On The Air Video

I’ve been thinking a bit about “Trail Friendly Radios” for VHF in preparing an article for QRP Quarterly. I came across this video about choosing radios for use in the Summits on the Air (SOTA) program. SOTA is a fun program from Europe that has found some interest in North America. The basic idea is an awards program that encourages operations from the various summits in a region. This has some similarity to the Colorado 14er Event and its associated awards.


Anyway, here is the video by Richard G3CWI:

0511-0701-3118-0930Catching up on the fine material spewing out of the web. Remember, if it came from the internet it must be true.


Newsflash: The DTV transition has happened and the world has survived. It just doesn’t matter, because it is television. To quote Joey from Friends, “it is a moo point….a cow’s opinion.”


Brian Wood, W0DZ, has opened a ham radio store in Loveland, CO. Good luck with it, Brian.


The Fi-Ni Report says there is a movement to regulate the speed of Morse Code. Really funny. I am not sure who is writing this stuff but their mind is sufficiently warped….which I like.


Did you miss the ARRL June VHF QSO Party? It was a party. Excellent 6 Meter propagation from Colorado to most parts of North America.


In the What’s Up with That Department, Riley Hollingsworth K4ZDH is now on the QRZ staff. I guess qrz.com is serious about cleaning up its act….they brought in the enforcer. I am a fan of Riley’s and best of luck to qrz.com.


From the This is Stupid Department, I came across this blog posting about teaching Fortran as a programming language in college. This is totally nuts. Maybe criminal.


I’ve been trying out Verizon’s broadband internet service, using my tethered mobile phone. I have to say this is pretty sweet, even if it costs $50/month. I was looking for a way to get internet up at the cabin in the mountains. No DSL or cable there, so the choices are limited. The Verizon signal is acceptable (could be better) but actually seems more usable for data than voice. (I guess we are more tolerant of dropouts on data feeds than on voice.)

Jeep Wrangler Radio Install

			
			                

                    Posted on   by                                      

					


		 		

			
One of my toys these days is a Jeep Wrangler (TJ) which we use for playing in the mountains. I finally got around to installing some ham radio equipment in it a few weeks ago. I mostly wanted to have good old 2 Meter FM – the amateur radio utility mode – in the vehicle. These days, it makes sense to include 70 cm (440 MHz) as well.


img_2349
The Jeep Wrangler


The first priority was to pull the old AM/FM receiver and put in a new Sony CDX-GT430. Crutchfield supplied excellent installation instructions and soon I had the center portion of the Jeep dash pulled out and the receiver installed. This work gave me valuable experience in pulling the Jeep’s dashboard apart. Not surprisingly, the Wrangler disassembles quite nicely with just a few screws here and there and a handful of those snap-in-place trim fittings to undo.


img_2355
Sony AM/FM/CD Receiver installed


The next job was to get a dual-band Yaesu FT-7800R 2M/70 cm transceiver installed. This is a one-frequency-at-a-time dualbander, very easy to use with all the required FM features. Originally, I thought I would just bolt the unit down in a convenient spot and call it good. As I surveyed the Jeep, I realized that I could do much better using the detachable control head approach (using YSK-7800 separation kit). The control head was mounted to the main plastic piece that covers the center of the dash using a pair of angle brackets from the hardware store. The radio box went under the back seat… somewhat protected from weather when the top is down and definitely not in the lower part of the Jeep floor. With the hardtop off, a hard rain can cause a small lake to accumulate inside the Wrangler. (I know from experience.)


img_2354
Yaesu FT-7800R control head


The most challenging decision turned out to be what antenna to use and where to put it. Mobile antennas are always a trade off between radiating effectiveness, ease of installation and overhead clearance. The Wrangler has a removable hardtop, made of fiberglass. This presents two problems: the fiberglass makes for a lousy ground plane and there will be times when we go topless. So a roof mount was not looking very attractive. Another choice was on the spare tire mount, which hangs off the back of the vehicle.  I’ve seen a few installations like this that look good. It looked like a more complicated installation and I was not sure how well the antenna would radiate off the back of the vehicle.


img_2359
Side view of FT-7800 control head with microphone installed


In the end, I chose to mount a short dual-band antenna on the hood near the driver’s side, using an NMO-style mount with one of the L-shaped trunk mount brackets. This is not the best location for antenna efficiency but it would be “good enough” for most use. The antenna is a 1/4-wave on 2 Meters, about 19 inches long, also tunes to 70 cm. The low profile has the added advantage of not getting pounded down by tree branches on the back roads. And I can take the hard top off without changing the antenna configuration. Did you spot the antenna in the first photo?


img_2360
Dualband 2M/70 cm NMO antenna


The Jeep had a obvious rubber plug that I poked through to get the DC power and antenna connections through the engine firewall. Per the usual guidance from the transceiver manufacturer, I connected the power cable directly to the 12-volt battery (with fuses in line).  The antenna seems to pick up a bit of ignition noise due to the close proximity to the engine, but it is tolerable.


Off to the mountains to have fun.

Recovering from Hamcon Colorado

			
			                

                    Posted on   by                                      

					


		 		

			
hamcon_logo_09It has been a few days since I left Hamcon Colorado at Estes Park, but the glow hasn’t worn off yet! What a great event!


Joyce K0JJW and I drove up to Estes on Thursday night so we could help with the final setup on Friday morning. Brian N5ZGT (ARRL Rocky Mountain Division Director) gave a fine keynote address on Friday night. This was followed by Harold Kramer WJ1B, COO of the ARRL. Harold gave a Powerpoint tour of ARRL headquarters, which I found interesting.


The real show started on Saturday with tons of excellent technical and operating forums. I admit to some bias here as I did a presentation on Test Equipment for Amateur Radio and did a team presentation on the Colorado 14er Event. I attended a presentation by Mike Higgins K6AER on Lightning Safety. Mike did a great job of explaining proper grounding of an amateur station based on his commercial experience. Virgil Leenerts W0INK talked about switching power supplies, also an interesting presentation. Mike Gruber W1MG (EMC Engineer at ARRL HQ) covered powerline noise…a topic that has gotten quite a bit of my attention lately. Mike (W1MG) and I (plus a handful Technical Specialists in the section) staffed the Doctor is IN booth, answering any and all questions from the convention attendees.  There were plenty of other forums that I could not attend based on other obligations but the feedback I heard was all positive. The only negative comment received was that we should have had a forum or two on contesting (valid feedback).


In between activities, I managed to chat with a number of hams I had not seen in quite a while. It is always good to connect up with old friends. W1AW/0 Special Event station was active…I did not get a chance to operate the station but I did make it a point to work them on 2 Meters with my HT.


We attended the banquet on Saturday night, also a great affair. Yes, it did go a little long but don’t they always? The breakfast on Sunday morning featured Gordon Harman W0RUN speaking about the Desecheo Island DXpedition. Gordon did a fine job mixing in a few tales from Peter I Island.


The attendance of Hamcon was 499, so the size pales in comparison to Dayton (duh). But I think the quality of the venue, the program and the people involved is far superior.

0511-0701-3118-0930Things have gotten quite busy at work, which is why I haven’t posted anything recently. The spare time I have has gone towards getting ready for Hamcon Colorado, as I have signed up to do two presentations and a few other tasks. Here’s some items that are worth mentioning that spewed out of the internet.


I haven’t seen the new Star Trek movie yet but Saturday Night Live did a skit relating to it. Also, the classic Shatner “Get a Life” skit is out on youtube. Both of these can be viewed here.


Speaking of youtube, the Society for Geek Advancement (huh?) has a video that features all of your favorite geek celebrities. Is “Geek Celebrities” an oxymoron?


The FCC posted some recent enforcement letters concerning amateur radio cases. Go Laura Smith! Included in this list is a nastygram to the idiots at Xcel Energy which is having trouble tracking down power line noise problems in Northglenn, Colorado. As the ARRL section Technical Coordinator, I had some involvement in this incident — all I will say is that it’s difficult to tell whether Xcel is incompetent or just irresponsible. Hard to say.


Speaking of the FCC, they have really gotten caught with their pants down in their analysis and handling of Broadband over Powerline (BPL). Thanks to the ARRL for keeping after them and getting the suppressed FCC documents via the Freedom of Information Act. Here’s a good article about it from an non-ham-radio source, ars technica.


K3NG raised the question of whether it is possible to have a useful amateur radio web site without the trolls and misfits. It seems that qrz.com is attempting to rise to the challenge. Good for them.


I stopped by the DTV.gov site that has information concerning the migration to Digital TV in the US. I was surprised to find that they added quite a bit of detail about when TV stations are switching over. Also, they have an interactive map that gives you estimated TV signal strength in dBm at an arbitrary location.  (Yes, real live technical information !)


From the Amateur Radio Fun in the Mountains Department, there is a group planning to create a packet radio link that extends the length of the Appalachian Trail (The AT Golden Packet Annual Event).  Sounds like fun to me.

Subject: [Committee] Email for your clubs!

This Spewed Out of the Internet #3

			
			                

                    Posted on   by                                      

					


		 		

			
0511-0701-3118-0930Here’s some things I found spewing forth from the Internet:


When Charles Simonyi was operating amateur radio station NA1SS from the International Space Station (ISS), I was looking around for the right frequencies to use, including doppler shift. I came across a really good web site on contacting the ISS. Check it out if you are interested in the topic.


According to Amateur Radio Newsline, the Indy cops that got in trouble for using ham radio gear for tactical communication were using modified Yaesu FT-2800 2-Meter Transceivers. With these radios opened up, they can operate outside the ham band on adjacent VHF frequencies. According to ARNewsline:


Some conversations were heard in the VHF police bands, at the bottom of the 2-meter band and on frequencies assigned to the MURS radio service.


MURS stands for Mult-Use Radio Service, an unlicensed radio service defined by the FCC. There are 5 MURS channels available: 151.820, 151.880, 151.940, 154.570 and 154.600 MHz.  These unlicensed channels would be a convenient location to hang out without the potential of interfering with anything important. However, a modifed amateur radio transceiver is not certified for use per Part 95 of the FCC rules.


I have not found any other information on the VHF police frequencies being used. Some departments maintain their licensing for VHF channels after adopting the newer 800 MHz radios. Modified amateur radio equipment is not certified for use on police channels. It sounds like these police officers were also using the low end of the 2-meter ham band. Even if they are licensed, it would be an inappropriate use of the frequencies. And a dumb one….of course someone is going to hear them and figure out what is going on.


You may have heard about Stephen Colbert from the Colbert Report getting his viewers to vote for his name on the new ISS module. It seems that he got the most votes but NASA declined to name the module after him (like that was going to happen). They came up with the alternative of naming a treadmill after him….all in good fun. The video is available on the Comedy Central web site.


On the K3NG Report, there was a funny post about the demise of phone operation on the ham bands, which is caused by the lack of testing for phone operating skill during the licensing process.


On the KB6BU Ham Radio Blog, there is an interesting post about the HP-35 calculator…a classic electronic product and an elegant design. The IEEE named the HP-35 and Hewlett-Packard Company as the recipient of the Milestone in Electrical Engineering and Computing award.

hamAs I sit here looking out the window, I see snow piling up on the back deck. Yep, spring time in the Rockies with a winter snow warning on Easter. It seems like a good time to take a look at upcoming amateur radio events this summer.


Here’s my starter list, with a definite bias towards Colorado, VHF, mountaintopping and radio contests:


Hamcon Colorado ( AKA the ARRL Rocky Mountain Division Convention) in Estes Park – May 29-31.  This is a wonderful event that comes to Colorado once every three years. As the gateway to Rocky Mountain National Park, Estes Park is a great vacation spot, so don’t miss it!


ARRL June VHF QSO Party This is The Big One for VHF activity – June 13-15. June usually has very good propagation on 50 MHz, so we’ll usually have a band opening or two on 6 Meters during the contest. If you are new to VHF contesting, see the article How to Work a VHF Contest.


ARRL Field Day– June 27-28. We are still not sure if this is a contest or not but the truth is you can make it whatever you want it to be! Arguably the most well-known and publicized amateur radio event. See my previous post.


CQ Worldwide VHF Contest – July 18-19. This is The Other VHF Contest during the summer, sponsored by CQ Magazine. This contest is gaining in popularity and is focused on the two most popular VHF bands: 6 Meters and 2 Meters.  Hey, CQ, if you want people to take this contest seriously update the web site with the 2009 rules! 


The Colorado 14er Event – August 9.  Focused on operating from the summits of Colorado’s 14,000+ foot mountains, this is The Premier Mountaintop Radio Event.   Check out the web site for full details….if you aren’t up to the mountaintop operating, then set your goal on working as many summits as you can from a more convenient location. Join the ham14er yahoo group to discuss and learn about the event.


The Colorado QSO Party – Sept 5-6. This contest is a fun event that focuses on activating the various counties in Colorado. Consider setting up mobile or portable to activate a rare one or two!

AMSAT DL Bounces Signal Off Venus

amsat-logo-semi-officialEvery once in a while, I stumble onto something that just makes me think “holy cow, how did they do THAT?”


The most recent is the German AMSAT group ( AMSAT DL) transmitted a signal to Venus and received the reflected signal as it came back to earth.


From the AMSAT (US) web site:




AMSAT-DL Achieves Outstanding Technical First:

Earth-Venus-Earth Path


Marburg, 27 March 2009 – On March 25, 2009 the AMSAT-DL team in Germany attained a major milestone in their mission to send a spacecraft to Mars. The team used their mission control station at the IUZ Sternwarte Observatory in Bochum to transmit a radio signal to Venus. After approximately 5 minutes delay and after traveling nearly 100 million kilometers the reflected signal from the surface of Venus was received. This was the first time a German station has received echoes of signals from other planets.


You may be aware that it is a common feat for radio amateurs to bounce signals off the moon and hear the return signal. Hardcore VHF enthusiasts contact each other on the VHF and higher bands by using the moon as a reflector. (Sometimes I kid them that using the moon as a “repeater” is cheating. Of course, it is nothing like that.) This mode is called Earth-Moon-Earth (EME) or simply Moonbounce. The path loss is high, around 250 to 310 dB, so high gain antennas and power amplifiers are required. EME is still on My List of Things to Do and I hope to get around to it someday.


If EME is an accomplishment, then consider the challenge of Earth-Venus-Earth (EVE).  The original press release is in German but the information is available in English on the Southgate Amateur Radio Club web page.  The signal traveled almost 100 million kilometers which results in a round trip delay of about 5 minutes. This is over 100 times the distance for EME.  The frequency used was 2.4 GHz, with an FFT analysis used to pull the signal out of the noise (with an integration time of 5 minutes). I have not seen an analysis of the path loss, so we’ll just use call it ginormous.


Why did AMSAT-DL decide to do this? Well, they want to prove out the feasibility of communications before they launch their spacecraft towards Mars!
