I have used this software on MSF on 60kHz as a means of manually setting
my PCclock, I have not tried it on the mode that electronically sets your
PC. There is obviously no timing errors or enormous errors with this manual
method, depending on your interpretation of "accuracy".

It is also worth looking at the same site for their "Beaconsee" software
that checks reception of the NCDXF HF beacon network and indicates in real
time the HF conditions. It also has a nice map of the world with real-time
darkness and daylight footprints.

Subject: Re: LF: DCF77 to synchronize QRSS transmitter / receiver

A decoder for these signals (using the soundcard) built inside a QRSS
transmitting/receiving program could be a nice, simple and accurate
synchronization source for synchronized or "coherent" modes. You would

only

have to feed that signal into the A/D-converter (soundcard) for a minute

and

could then tune the RX to the operating frequency. The PC's internal
real-time clock will be accurate enough to generate the "second marks" for
some hours.

There is a program at this URL http://sapp.telepac.pt/coaa/radioclock.htm
called Radio Clock.  Uses the soundcard to decode time signals.  Tested it
here in the US and found that for some reason it is 1 minute off.
