Between 19:58 and 20:28 there was a strong and stable signal on 137490.0 Hz, coming in from west or southwest. However the keying seemed to be in 90° steps instead of 180°, so not decodable. Maybe a
Hi Markus, EbNaut It was me, with 80w from the D class PA I'm producing 180° phase shifts with xor at 2x the frequency to feed the PA. So it seems that the PA do also reduce phase shifts to half :( W

Thank you Riccardo And thank you Antonio too, for the complete information in the web page I will make a pcb with the 4013 and 4070 to be piggi backed into the 4013 shocket 73 de Luis EA5DOM De: owne
Another idea: You might get away with the XOR before the /2 divider if you use it to insert an extra short pulse at each PSK edge. Don't know whether this is really reliable due to asynchroneous timi
