I know this has been asked in the past, but things change and new

FreeBSD to use for an NTP server? Is the same version recommended for

Well, fluke currently only has the GPS16 HVS. The least expensive
GPS18x LVC I've found so far (on or off ebay) is here:

Ah thanks for that Poul I knew there was some data on it which averages out
but was not sure what it was. I have a source locked to Droitwich here
(which doesnt have time-code), but I have never had a successful lock to
Allouis (an option on my off-air unit) Possibly the local noise is the
problem
Can someone provide a link? I can't seem to find it...

They send DCF77 like timecode with phase-shifts.

Hi Magnus TDF (?) France Inter ( Allouis ) is, I believe, a strictly

to a rubidium and measured by the French national bureau I expect. Details
of MSF and Droitwich are available from NPL

Hi Magnus,
The BBC's "Radio 4" signal on 198 KHz should be another contender. Beware
that it has slow (25Hz?) phase mod that carries commercial data signals. From
memory, the data packets are 50 bits each, so each spans 2 seconds. Time is

Fellow time-nuts,
I am trying to make an overview of VLF time stations that can reach
Sweden and may be of practical use.
Loran-C at 100 kHz seems obvious.
DCF77 at 77,5 kHz (50 kW in Germany) is known, certainly within range
(my receiver works without much trouble).
MSF at 60 kHz (17 kW i
