All,
Marty and Walter seem to be reporting some success through the PCSAT2 10 meter PSK-31 uplink! Here is a preliminary report, and it seems to imply that the frequency is off and so that may be why many people have had no success. I am stealing their thunder here to encourage others to try the transponder if they have plenty of uplink power on 10 meters.
He starting drifting down in frequency, and I could see it > come up on the water-fall in MIXW, when he was 3.6khz lower that what it was supposed to be.
I was not able to decode any data, but the data stream was there, and we validated that it was him, by when he un-keyed, and re-keyed, it went away, and returned respectfully.
Thanks for the testing! Only a few days to go before PCSAT2 goes QRT. (first EVA shut down will be 9 Sept).
The PSK-31 FM downlink is on 435.275 and the uplink is supposed to be 29.400 to 9.403, but the report above suggests it might be below 29.400 a few KHz.
To activate the PSK-31 transponder, send a AX.25 connect request to PCSAT2 on the 145.825 packet uplink.
