what's a good start freq for PSAT using DopplerPSK?
I made the last pass but was maybe 2KC higher. Also, I only see myself when the Robot-Beacon comes on.
Saw two other guys calling CQ .. Looks like they too were using DopplerPSK
One was KC4LS btw
Bob,
If you are too high in the pass band / waterfall you can adjust the center frequency down a few hundred Hz in the settings file. Or just tune the VFO of the 10m radio a little until you are where you want to be on the waterfall.
I have noticed the ROBOT-Beacon does turn on the NO-84 transmitter at times. If you are not turning the satellite on, use more power. 40- 80 watts works for me most of the time. Expect your signal to be noticeably weaker than the telemetry down at 312Hz.

Bob,
thanks.
I was just now trying. I tried about every 100hz from 118 to 121 and never broke the squelch.
Using 90 watts.
My guess is that 28.1215 should put you close to the center of the passband. And remember, you can just keep the key down throughout the pass... it is full duplex and so you can see if you are colliding with someone in the display.
Though listen first on 10 meters, since we are using the same common frequency band as terrestrial users. BOb

I didn't hear the Robot tonight and thus I never had a signal/waterfall.
Is she off duty on Monday's ?
