NO!
Do people not have SSB and CW equipment or are they just not interested anymore."
That is Hard to say,,
Tom, speaking only for me, I have tried several times to work a linear. I have a TS 2000 with the sat function and HRD sat program which allegedly adjust the Doppler, 2m/440 SSB and a Elk on a rotor w/fixed el.. Try as I might, I cannot get the tx and rx to match so I can duplex.
There is a simple fix to this,, SHUT ALL THAT CRAP OFF! In the 70's we didn't have anything like that. The flight computer if you were lucky to have one was a piece of cardboard with a clear plastic overlay to tell you where the Bird is, An "Oscar Locator" it was called.
As far as doppler correction,,, we turned the large knob on the front of the radio, thats our doppler correction system.
There just does not seem to be single primer that one can follow on how to accomplish the process. There are multiple opinions from individuals, but not much of a consensus on a good standard process. Admittedly, I have problem not given a fair amount of time on my technique as I was concentrating on VUCC. Now that that will go to the card checker tomorrow, I need to spend some time on the linear. I just wish there was a 'manual'
It's called doing it "Manually"
Simple and very effective thousands of hams did it for decades, no reason it won't work now.

Hi Joe, WB9SBD
I agree completely with you because I started to work satellites with OSCAR-6 not to collect grids but to improve my knowledge in radio tecnology.
Put now an "Oscar Locator" in the hand of a satellite newcomer is like to say to him to drive a Ford Model T called also Tin Lizzie or Flivver and he will bump into a wall !
