Hi Markus, Uwe, VLF. =C2=A0=C2=A0=


Yes, it was me (no escape with Paul's RDF :-) )...I'm very sor= ry for this misunderstanding.
Markus, I'm testin= g (but now in local) your SL's TX configuration (#18.ini).
Now, I have got some problems with digimode modulator to generat= e a correct BPSK signal using the file created by EbNaut sender.
Around 8270 Hz, the carrier phase is in continuous rotation bu= t a few Hz away is locked and OK. For your info, I'm using the 10kHz GP= SDO signal (ch. R) instead 1PPS pulse.
Please, have = you any suggestions?
Thanks so much.

All the best
