[time-nuts] VLF time stations in Europe

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 in GB) also works (a friend has working reception).

TDF at 162 kHz (2 MW in France) should reach according to published 
chart, 3500 km range includes all of Sweden.

HBG at 75 kHz (25 kW in Switzerland) may be a little to faint to be 
useable? 1000 km range seems too short. To close down in 2011.

I know of the Russian military Beta signal (20,5 kHz to 25,5 kHz), but 
consider it of less importance in this case. Is received in Norway where 
reverse-engineering has been done.

I also know of Chayka, the Russian equalent of Loran-C. Considering to 
include it.

I assume that signal should be of considerable strength such that 
regular use does not require DX-ing skills and that fairly regular use 
can be made without having to figth wars agains S/N issues.

Can anyone spot an obvious missing signal?
