When Fox-1 is completed, the whole design kit and kaboodle will be published to shed the ITAR shroud (as we have done with what has been developed as we go along, in the AMSAT-NA Space Symposium Proceedings) and anyone who wants to build one can use it or adapt it (hopefully keeping the ham transponder!) for their CubeSat RF design and fly it in/from/for another country with their experiments. The idea being as JoAnne said, the radio part is proven and provides a platform so they can concentrate on their experiments and build a CubeSat that handily just happens to contain a transponder for hams during, or when they are done with, their experiments. Of course if ITAR restrictions are eased or removed, then AMSAT-NA could collaborate with other countries as well and incorporate their experiments as we are doing with our U.S. partners now.

[amsat-bb] Re: N American Satellite Activity UP
A small correction to JoAnnes Email: FUNcube boards are also able to run both TLM and voice. Thats actually what it is always doing in transponder mode. only the TLM is brought down 9dBs to allow for the transponder power. This 9dB number is also settable in the on board software, so it need not be 9dB. However, this seems to be a reasonable number, as well equipped stations can still copy the TLM easily, and on quiet RF environments, so does an arrow + FT817 or FUNcube dongle. FUNcube boards are now in three more missions, of which two are scheduled for launch this year. Thanks JoAnne for pointing out the existence of these boards, and lets hope some more CubeSat teams decide to use FOX or FUNcube boards. This seems to be the best way for the community to make the best use out of CubeSats for amateur radio. Regarding the world wide collection of telemetry: point at http://warehouse.funcube.org.uk and have them play ;) Or have the students download and analyze ARISSat-1 telemetry at http://www.arissattlm.org/ Another statistic: The Delfi-C3 telemetry collection database now contains 2016683 frames and has 375 signed up radio amateurs submitting data, and many more on the guest account. Our community really has a lot to offer to CubeSat teams!

[amsat-bb] Re: N American Satellite Activity UP
I'll just add in that I have only ever operated a satellite by handheld antenna and an HT. I've received SSB sats on stationary antennas but never worked them. I don't have the infrastructure to do so nor have I had the time to set something up. I just graduated college and moved 3,000 miles across the US to Los Angeles (South Bay area) where very few people own their homes and like me rent. I really can't install and antenna and feedline and everything must be portable. One day I'll get a semi portable station together but until then I enjoy helping others get onto the birds (AMSAT Engineering) and hearing other people have fun working them. Same story for my involvement in K2GXT at RIT. I hardly ever operated in college but spent a majority of my time helping others learn the ropes in ham radio, making sure they had access to the equipment they needed, and transferred any experience I had to them. This makes me content to know that my efforts let other people have fun. On that note, since LA is a pit of RF noise (especially HF at night!) I've toyed with the idea that once my college loans are paid off (that... will take a while) to team up with some other hams I know and purchase some cheap land in the middle of nowhere (like Mojave Desert area) with access to power and internet then set-up a remote station to operate HF/satellites. It would be a neat project and probably make my HOA president much happier :D. Just my $0.02 and story Bryce KB1LQC On Sat, Mar 29, 2014 at 3:21 PM, Michael wrote: > Been down this road before.
