Southern CA Satellite Presentations
ARRL instructor and ARISS / AMSAT-NA / AMSAT-UK supporter Clint Bradford, K6LCS, will be presenting his 84th and 85th satellite presentations in September.
"I have no idea how I have "missed" the Downey (CA) Amateur Radio Club," Clint writes. "They are long-time ARRL supporters, and have been serving their region well for more than FIFTY years."
"The Victor Valley (CA) ARC is another story. This will be my fourth show for them these past ten years. I suppose I will have to change some of the bad jokes that are interspersed throughout the presentation ... "
Attendees will be shown EVERYTHING needed to work the FM voice ham satellites – with a re-occurring theme of, “Most hams already have most of the necessary equipment … ” Attendees can download a four-page tutorial beforehand at …
… and Clint welcomes pre-presentation questions. Call him at 909-999-SATS (909-999-7287), or send email to clint@clintbradford.com .
Not in the Southern California region - but would like your club to experience an hour-long educational and entertaining presentation on working the FM birds? Send me an email - I will bring the show to your club!

It sure would be nice if you would quit telling people that full duplex is "not mandatory" for working sats. It absolutely should be MANDATORY. Having full duplex should be stated as rule # 1 of operating on a satellite regardless of which one it is and what mode you are operating. Not using full duplex results in needless interference and frustration. Just my humble opinion. 73, Michael, W4HIJ On 6/26/2016 2:49 PM, Clint Bradford wrote:

I humbly agree with you Michael. Even though I do understand that some Hams can not afford a second radio, the swarms of cheap radios on the market lately has pretty much alleviated that issue.Maybe it's not always possible, but attempting full duplex is not only better practice, but is a very gratifying challenge to anyone that hears what the have been missing.
I give you a thumbs up sir. KC4ZVA

The cheap radios can have issues with harmonics desensitizing them.
While I also agree that full duplex is very useful, I think you are asking to much of a new ham (at least) to spend close to $250 in radios to try something. That's if they build their own antenna and have feedline handy.
Now, if a ham happens to have two HTs of decent quality to be put to use, that is another story.

Oliver,
Hams don't have to spend $250 to try satellites anymore. Yes, the Chinese-made radios come with varying quality control. If you get good examples of those radios, you might only spend $50 or $60 for two radios. I have worked SO-50 with two Baofeng HTs - two UV-5Rs, and one UV-5R with one UV-82. The two UV-5Rs cost about $60, and the UV-82 was about $37 when I bought it in 2014. I even used a Baofeng pair (transmit from a UV-82, receive with a UV-5R) for a hamfest demonstration in May 2014 - illustrating that working satellites doesn't cost much money for the radios.
If a ham already has a decent dual-band HT, a $25 or $30 Baofeng HT as the transmit radio in a full-duplex FM satellite station is (my opinion) not asking too much. Are there hams who can't afford even $25 or $30 for another radio? Sure. But at these prices, the arguments against actively encouraging full-duplex operation pretty much go away.
Why do I say that the Baofeng HT should be used as the transmit radio, and not the receive radio, in the two-radio example above? In most cases, the non-Chinese-made HTs have better receivers for satellite work than the Chinese-made HTs. There are some Chinese-made dual-band HTs have receivers that do a good job with our FM satellites, and I had written about some of them when I reviewed a few for use with AO-85 a few months ago in a series of posts on this list.
Yes, hams don't need to go full-duplex to work FM satellites, especially those with 2m uplinks like SO-50 or LilacSat-2. This is a true statement. I even worked a LilacSat-2 pass last night during Field Day using a single Wouxun KG-UV9D HT - a radio that can work U/V satellites like AO-85 and the upcoming Fox-1 FM satellites full-duplex, but not SO-50 or LilacSat-2 due to desense issues when transmitting on 2m. The audience I had last night saw that it was possible, but also saw me working SO-50 and XW-2F full-duplex earlier in the day, and saw the advantages of working satellites full-duplex.
The antennas can be homebrewed. The WA5VJB "Cheap Yagi" design is a great dual-band Yagi, for those not interested in spending $125 to $150 for an Elk or an Arrow. Using a 2m/70cm antenna is desirable over the 2m-only Yagis of various designs, especially since we now have FM satellites that require a 70cm uplink like AO-85 and the other Fox-1 FM satellites in the pipeline.
The best part about all of this - all of this gear can be used for non-satellite activities. Local repeaters, simplex, and (when paired up with a TNC or software on a computer) even packet. The packet setup could be used with terrestrial packet, or with the orbiting digipeaters on the ISS and NO-84. This is a lot better than the situation in the past for working satellites.
And, in keeping with the title of this thread, I will give a satellite presentation in southern California during September. I will give a presentation at the Jet Propulsion Laboratory Amateur Radio Club's monthly meeting on 23 September 2016 in Pasadena, discussing current and upcoming amateur satellite projects. I'm looking forward to making my second trip for a presentation in California this year, after a presentation in Long Beach last March. Along with answering questions about my presentation, I'll be happy to answer other questions about satellite operating from those in attendance at that meeting.
73!

Any plans to demo the satellites on this presentation? Some of us are always available to be the voices at the other end of the satellite (AO-85, SO-50, FO-29, etc).
It will also give us an opportunity to add you to our logs. I've been doing this since October and haven't heard you on one of the birds yet.

Well, Fernando, if you are lucky enough to make a sat qso with Clint, don't hold yer breathe for a QSL card. Despite SASE and email promises, good old 'Clint' never got around to it x3 (2010). Oh well, made the VUCC anyway..

p.s. Clint, don't need it now
