Fox, "Easy Sats" - segway to PSAT PSK31?
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..

Yes, I'd like to try it myself, but my apartment QTH makes it tough. I'll get to it at some point. I have copied the downlink. It's a nice strong signal. I just have to figure out the best way to manage to transmit as well.
My belief is the uplink frequency choice was a mistake. Why mix terrestrial and satellite users on the same frequency?
A nice quiet frequency in the OSCAR subband would have been a better choice, in my opinion.

Because without them, we'd have no signals at all.... ;-)
