It sort of puts to lie the argument that transponders are hard to use. I suppose it helps that they are in geosynchronous orbits.
I especially found this part interesting:
"I saw it more than once in truck repair shops," says amateur radio operator Adinei Brochi (PY2ADN) "Nearly illiterate men rigged a radio in less than one minute, rolling wire on a coil."

Yeah... I believe this has been going on for a number of years. (I recall reading about this on another board.)
I believe the satellites in question use FM and geo stationary orbits and have up links and down links in the miltary UHF band (225 thru 400 mhz.)
Kind of makes you wonder what would happen if there was a geo stationary amateur satlleite that was easy to use. If pirates will hack military satellites then I doubt they would have any qualms about using an amateur satellite.

One of the primary justifications (for someone to subsidize the launch cost) I have heard floated for a amateur radio geo stationary satellite has been public service and emergency communications. How would those on the list here feel about such a satellite should it come to exist being able to be configured such that only authorized users could use it and others lacking the channel keys would have no access, nor could they interfere. I'm thinking for certain circumstances a jam resistant controlled access mode on such a resource could be useful. What do you think?

Eric...the "instant" things start "being reserved" for a group of amateurs...for any reason other then by regulatory action...we have started down a very slippery slope that has no real end.
The FCC can and does "set aside" frequencies in serious emergencies for special communications and then they end it...the frequencies belong to The Republic. To be blunt..the way AMSAT has mishandled the amateur satellite acquisition system since the ramp up to AO40 would in fact tell me that they shouldnt be trusted with just about anything much less who gets on the bird.

I ditto those statements entirely... Also would any frequency be taken from other hams (most likely) or would an additional frequency spectrum be allocated... Frankly Elitist suggestions like this make me think of Big Brother... Do you really want to make hams go through more of the BS the posting daily on how and what you can do on the amateur bands?

What I was referring to is the ability to set aside a few communications channels on a temporary basis that would be relatively immune to interference and kept clear for use by those who needed the resource such as a net serving an affected area. I hope I wasn't misunderstood from that. I was in no way suggesting that any spectrum be reallocated away from the amateur radio service, only that a means may be considered for certain channels to be protected from interference using technical means for a limited duration while those participating in the sanctioned activity needed the resource for the benefit of the republic as a whole. Is such a system capability such a bad idea?

Yes it is for the exact same reason that the Aeronautical service still uses the (relatively) noisy AM mode as opposed to FM for air traffic control. The notion is that someone one need can break into the system at any time with emergency traffic... what you are proposing is a link wherein only elitist users can enjoy the benefits. I suggest that with the FCC allocations of emergency frequencies as needed, where needed, and the demonstrated ability of hams to cope previously you are adding yet one more layer of non productive regulation to an already overloaded system. As a founding member of SATERN and more than once having been written up in WST for my emergency radio work, I think I am familiar with both the problem and the solutions to them, please don't reinvent a wheel that is already working.
A last comment, a LEO would be virtually worthless for Emergency NET communications and HF is still a viable and reliable means of communications... If there were a HEO or GEOSync bird up and if it was needed, I am certain that it would be used... Nuff said. ----- Original Message ----- From: Eric Fort

Well, I still think a bunch of 145.825 APRS digipeating satellites in LEO that would allow text-messaging from anywhere in the world at any time, downlinked into the APRS-Internet system and hence global internet connectivity is still a great way to go for basic messaging for emergency response. With just 6 such tiny 4" cubesats, you could get a message in-or-out with no more than a half hour wait from the front panel of your APRS mobile radio. With a dozen of these, you could have global communications anywhere instantly or with no more than a 5 minute wait.
Our goal is to get more of these up there to join the ISS digipeater, but of the 4 we have lanuched so far, all were short-term orbits and so the most we have ever had operational at one time was 3 (PCSAT-1, ANDE and RAFT). That is one of the main reasons we wanted to see ISS on 145.825 to join the constellation. ISS was still on 145.800 during most of the life of those three birds (which were all on 145.825)
Today, with 6 AA NiCd's, a 19" whip antennna, and a 3.4" square APRS Microtacker TNC/Radio you can throw together an APRS satellite for under $400. Add cheap solar panels, a lot of sweat equity and then find a school to provide the $50,000 launch, and bingo, A LEO satellite with great utility that anyone can use while mobile for text messsaging and email from the front panel of their APRS radio.
Please see the Microtrack TNC/Radio which can serve as the entire Comms, Command, Control and Telemetry module:
