Subject: LF: Russian "Alpha" VLF beacons
Sorry this is not LF but VLF (which is more interesting to me these
I observed a frequency change of the three russion "Alpha"
(RSDN-20) transmitters. At the moment, they are very strong on
12696 Hz, and 13283 Hz
with a small active indoor loop. The
"old" frequencies used until a few days ago were
12649 Hz and 14881 Hz .
They must have a nice variometers or a lot
of taps on their loading coils ;-) ... anyone got more info about these
'beacons' ? Especially interesting would be their location and "official"
accuracy of their frequency / phase .
