[amsat-bb] DopplerPSK

[k6vug at sbcglobal.net]

 I'm very curious about this, thanks for sharing the links.
Looks like the program adjusts the PSK modulation within the pass band of the uplink, and at 10 meters, that would be relatively small.  It makes sense, however would this work if SatPC32 manages the uplink ? 
 
Secondly, I came across this on the website:  
 
"DopplerPSK does not provide any PSK31 demodulation; you should use a separate program for that purpose. DopplerPSK does not provide any compensation for downlink Doppler (which you would need for fully linear transponders)."   
Question 2 - why not use something like HRD for everything (doppler, psk, rotator, logging, etc) ? 
(I believe I tried it sometime back by routing of the downlink audio back into HRD) 
 
73!

 I originally used the link on 2M0SQL's excellent how-to page:

https://www.2m0sql.com/2018/10/29/using-the-no-84-psat-psk-transponder/

... which is:

If that link isn't available, you're welcome to the copy I downloaded which
has just been put at:
