Re: [amsat-bb] Fox, "Easy Sats" - segway to PSAT PSK31? (X 2)
Don't forget we actually launched TWO identical 10m PSK31 uplink and UHF FM downlink transponders (Built by Brno Univ).
SO if you go for PSAT, be sure to set up 7 minutes earlier in case BRICSAT comes up too. BRICSAT has the same PSK31 transponder and appears to be 7 minutes ahead of PSAT. I just heard it at 2211z. It is power starved, however and only comes up now and then when its battery accumulates enough juice.
And of course, neither comes up unless there are users in the 10m 28.120 MHz passband.

Segway this argument to the 10m uplink now 100% available on PSAT PSK-31 which virtually no one is using.
With OSCAR 6 and 7... ten meter downlinks, it was just a matter of
adding two meter transmit capability to an HF station.
For PSAT PSK31 it is even simpler. Add a UHF FM HT to your HF station!
many... people that worked OSCARs, 6, 7, 8, and RS birds never graduated from Mode A... Just like many of the FM satellite users never graduate from FM.
We give them what they ask for, a multi-user simultaneous transponder supporting dozens of simultaneous contacts, yet we have only seen 1 or 2 stations at a time give it a try.
Just an observation. I thought this PSK-31 linerar uplink with FM downlink would make everyone happy. It's a foot in both camps..
<wink> Bob, WB4aPR
NO-83 and NO-84 are far enough apart now that the FM down links will not "Double" with each other. With that, I have never heard or seena telemetry signal from NO-83 W3ADO-6. It should show up around 375 Hz on the waterfall. I have been unable to turn on the transmitter with a PSK31 signal.
Has anyone copied this satellite? Either the PSK-31 telemetry, or thru the A/u USB/FM transponder?
If so, what is the secret ? Or is it just low and intermittent power?

So Bob,
Are you saying that I will only hear the W3ADO-5 beacon at 300 Hz when someone is actually transmitting on 10m? That might explain what I have been seeing on several passes.
I have been listening for the last two days (before transmitting) after your message got my interest once again in satellites (haven't turned the satellite rig on since ArissSat).
I do see some faint signals that Digipan does not seem to decode. Will try some other decoders. Just lashed together something quickly to listen.

Yes, but go ahead and transmit. It is full duplex and so you should see yourself in the waterfall. Bob
