My understanding is that 1000's of these are deployed on commercial ocean
bottom seismographs (Co. name not important) and per my last conversation
with them, that they had identified long term failure's on the CSAC. They
also indicated that they could detect when failure was imminent, and that
A little while back there was a discussion about some of the issues using the
PSIP data from digital TV broadcasts as a time source... it's not a good idea.
Here is some data of why not:

I have two DTS2070s. The only manual I can find now is one for the DTS-2079. No
schematics, but, a whole lot of other info. Can email it to you if you would
like. Regards - Mike

MSF Scheduled Maintenance Periods
The MSF 60 kHz standard-frequency and time signal, broadcast by Babcock on
behalf of NPL, is occasionally taken off-air to allow maintenance work on
the masts and antennas at Anthorn Radio Station to be carried out in safety.
This means that your
This is a great list. Thanks everyone! Much of the material relates to
cases where good holdover needs to be maintained for several hours,
but there's a lot of insight to be gained from the reading, and I am
sure those techniques will come in handy for other projects. Thanks
again!

The latest rev of the CSAC data sheet (rev H) shows the max
non-operating temperature to be 40C..
and operating from -10 to +35C
that's a substantial difference from the former version of the sheet
which presumably had the temperatures from the summary page:

A couple of years back I could receive MSF fine (Gouda, the

comes in at all. The led on the radio also flickers dramatically, not

Folkert,
As far as I know the transmitted signal has not changed and is its
normal strength with me. Have you thought that you may be experiencing
some form of interference to the signal? If you can monitor the signal
on a receiver, maybe on a long wave broadcast receiver, you may find
