Hi Ric,

your phase seems to be perfectly corherent (apart from a minor frequency deviation, which might well be due to propagation).

BTW Today I've tried to generate PSK directly from a u-blox LEA-6T, by sending it CFG-TP5 instructions which switch between rising and falling timepulse-edge. Seems to work fine...

Best 73,
Markus (DF6NM)

Jay,

I'm monitoring on Markus autodecoder.
Now I'm running with a single NEO-M8T, my old GPSDO is being decommissioned.
TP output is the 1PPS signal for PC audio card (SL is running with a PLL configuration), TP2 is generating the 544kHz signal clocking the RTX SDR (quadrature H-mode mixer).
I hope for phase stability...

Looking for Riccardo and Stefan ... and anyone else that might want to join in.
 
Riccardo ... has your phase jump problem been corrected?

Sorry, +2 Hz I think it's more adequate. What say you? So, correction:

QRG: 137547 Hz

coding 8K19A
CRC 8
3 sec./sym.
8 characters
duration 29 min. 36 sec.
(every 30 min., 1st tx on 2000z, last on 0700z)

Many thanks.
