Yes, Markus, my TX  has been ZOA with SpecLab set to phase = correction.
all grabbers show a vy clean line never = seen=20 before. Thanks for that .USR file.

But=85..

I had problems finding a proper soundcard. At last a new sound = blaster=20 audigi made it. But not 100%.
To get the 1PPS peaks ok, the record = amplifier=20 must be set to 100% and no NMEA signs to receive.

with  SpecLab settings not using the phase correction the=20 soundcard recorder must be set to abt 2% to get the 1PPS peaks and NMEA=20 ok.

With other soundcards =96 like an vy old Sound Blaster, Musen = and=20 Generic  - the 1PPS and the NMEA signs where ok when the record = slider was=20 set to 100%. But obviously no phase correction occurred. Rainbow colours = in the=20 trace.

Ok, it is all fine now, the trace gleams in lime green, i.e. = 180=B0=20 locked.
