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!
