P.S. The SSTV is automatic once every 2 minutes or 4 minutes depending on Energy levels. But ONLY in spacecraft daylight.

The PSK31 audio downlink does not activate unless someone is TXing PSK31 on the ten meter uplink. That is around 29.4815

So I guess there is nothing to hear unless we get some people on the ten meter uplink. (this is unlike PSAT which has an uplink in the NORMAL terrestrial PSK31 frequency and there is usually someone on (unknowingly being relayed). Not so for PSAT2 which has to have someone transmitting first. But if you do, you get the full transponder for the full pass as long as you keep transmitting. Others can join you a few dozen Hz away and have a multi-way chat.

Although we have lost the PSAT-2 VHF downlink, the UHF PSK31 and SSTV camera are still on 435.350. We have been asked by authorities to confirm that PSAT2 is correctly catalogued as 44354? (I believe it is)

Similarly, USNAP1 is still beaconing once a minute on 145.825. They are asking if it could be 44357 (OBJECT U) instead of 44355

Having moved out of our lab/groud station of 27 years we have no antennas and cannot easily do this until the spring.

Thanks
