Hi Roland and Marco,


Marco IK1ODO wote:
Interestingly, the opposite here... not able to copy the PSK08, but some acceptable copy in PSK31:
Indeed .. maybe the longer path suffers more from slow phase shifts, which affects PSK08 more than PSK31. Did you have the AFC on or off ? (in the presence of QRM/QRN, it is often better to turn the AFC off; which is what I was using). Without the AGC, the tuning indicator (vector scope) showed only vertical lines as it should - in BPSK .

Cheers,
 Wolf DL4YHF .
