RUSSIA / USSR RWM broadcasting frequencies 4996 kHz, 9996 kHz, 14996 kHz
QTH - Moscow region, Taldom. Doppler ionospheric observations of the exact
time station RWM. Author: Vitaliy Melnik UI7K.
As a result of numerous experiments, a three-frequency RWM signal receiver
(broadcast frequencies 4996 kHz, 9996 kHz, 14996 kHz, which allows you to
simultaneously observe and evaluate three RWM signals. The station's pro-
gram guide is a repeating half-hour interval where the carrier is trans-
mitted for the first 8 minutes, then pause - 1 minute, RWM callsign trans-
mission - 1 minute, transmission second pulses - 10 minutes, transmission
of 0.1 second pulses - 10 minutes.
The most informative for us is the transmission interval, the carrier ...

RWM [and US&Hawaii WWV/WWVH too] standard fq services worldwide - in use
almost daily to align always Perseus server to even exact .000 kHz fc,
great USSR / RUSSIA service too, many thanks to Taldom Mr.Andrey Shaydurov
and technicians service too, - 73 de wb.

RWM: Victor Rutkovsky on open-dx drew my attn. to this article about the
Russian time-signal stns on

In short, the standard time and fqy stns RBU 66.66 kHz, 10 kW and
RWM 4996, 9996, 14996 kHz are planned to be transferred from Elektrostral
/ Noginsk (Radiocentre 9) to Taldom (Radiocentre 3) in the first quarter
of 2008. {or May 31, 2005 year ?}
Taldom engineers have done the preparational works (repairing/constructing
antennas and xmtrs, including the unique "Zont" antenna system for RBU)
during 2006 and 2007.
