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

Hi Luis, Markus, LF
Yes, Luis. Like Markus said, you're using a wrong position to change the phase.
With Tony IK1HGI, we have tested a solution to produce a correct BPSK modulation using a G0MRF PA schematic. Here's the link to Tony's website page, that explained clearly what to do:
In short, the XOR operation must be carried out after the x2 stage (D-ff, CD4013) simultaneously on Q and Q denied signals.

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 :(
Which would be the way to do it ?
Congratulations for the EbNaut grabbers
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 problem with a /2 divider in the transmit chain?
