Re: PCSAT2 Testing on 10 meters



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.

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.

de Wb4APR, Bob
