There is a russian station at 200/3 kHz with timesignals, it's a bit
too faint on my antenna to be usable.

Are you talking about the Omega clone in the 9-12 kHz range or some
other transmitters ?

In general most of the Russian stuff keeps lousy time, some of them
wander off and only get adjusted twice a year etc.

It's pretty tricky to get a good signal out of, because the GRI is 8000
which means that you cannot filter CW noise out by integration.
