Hi Michel,

I believe that RX timing was= correct. The clock of the LF grabber PC is controlled by an NTP Client, an= d my Loran-C grabber is running on the same machine. If NTP had been off by= more than a second, the Loran monitor would have jumped to the wrong 1pps = pulse and lost the Loran traces. =C2=A0

Hi M= arkus,

Does this 3second time offset come from my side ? No in= tentional change to blame !
Could be a glitch with the VK16E GPS receive= r - used only for NMEA, not for the GPSDO.

Hi Michel,

after I realized that the time offset was now = 3 seconds I got a few more decodes. Apparently SNR and condx were a bit wea= ker than the night before.

Yes the undefi= ned state of a divider before the PA can cause problems for coherent EbNaut= (or Opera) transmissions. With the DDS, you could try to gradually advance= the phase in 64 small steps to accumulate 360=C2=B0.
