If Droitwich is passed through a 1Hz bandwidth filter there is no sign whatsoever of the residual phase mod. I was receiving 198k this morning before deciding to change to 77.5 for the evening run. D
Hi Jim's idea of monitoring Droitwich might not be so good. Don't forget there is a 22.5deg. (or somthing like that) phase shift keying on the carrier, for control purposes. Unlike DCF39 the residual
Just for a bit of a challenge I've just set up the receiver monitoring DCF77 on 77.5kHz, with the Caesium beam turned on for the first time in over a year. It was very disconcerting to find that I wa
Dear LF Group, Thanks for the reports on last night's tests. It is nice to see that it is possible to maintain the timing and phase of the signal over quite long periods of time, and that Andy's demo
Absolutely perfect copy of the GPS locked BPSK signal from Jim at the low power setting. Although, at this power the signal can still just about be detected by ear, so I'll be more convinced when the
At the moment that is basically all that I'm using. An analogue vectorscope made by multiplying two quadrature 1kHz waveforms by the output fom the Rx after passing though a 1kHz bandpass filter. The
Dear LF Group, As a "confidence check" of the GPS time/frequency standard stability, I monitored the phase of MSF relative to the standard's 10MHz output. MSF was received using an SPM-19 selective l
