** RUSSIA [and non]. VOR is still way out of whack, putting out big dirty spurs
over portions of the 15 MHz band, interfering with many other stations and even
itself! Sat Oct 13 at 1340, found Greece`s English hour on 15630, Hellenes
Around the World, unlistenable due to the QRM. VOR in Hindi on 15605 also had
the QRM, which peaked roughly 15615-15630, but the spikes were also audible
above that and below including 15550, which is the nominal frequency of the
offending transmitter, ironically, with the same programming as 15605. On 15550
itself, no carrier audible, just the spur`s extremely distorted modulation.
Also QRMed VOA in Russian on 15565, and even the much stronger RDPI on 15560.
At 1359 the VOR transmitters went into IS, but not synchronized with 15605.
That frequency had switched program feeds and at 1400 played NA as opening to
English service, while the spurs continued, now having switched to Urdu which
to the Oklahoman is indistinguishable from Hindi. At 1401 NA could also be
heard weakly on 15660, the // during this hour for English, but these were not
exactly synchronized, 15660 running a few words ahead of 15605 once they
started talking.
Meanwhile I looked for the further spurs Wolfgang Büschel reported the day
before in the 16.2+ MHz area. There was a continuous buzzing motorboating sound
at 16220-16250 or so, peaking at 16235, but nothing resembling program
modulation, so I could not correlate this with any of the VOR 15 MHz channels.
Nor was there a matching sound in the 15.0-15.1 MHz range.
Quit listening for a while, but quick recheck at 1446 found the 15 MHz spurs
gone with 15605 in the clear; there was a weak non-distorted signal on 15550,
language unknown. Apparently in the meantime the malfunxioning transmitter was
taken off the air, or possibly knocked back into whack. Per Aoki, it is
scheduled from 3718E, 5545N for a07:
15550 VOICE OF RUSSIA 1200-1300 1234567 Urdu 500 140 Moskva RUS VOR
15550 VOICE OF RUSSIA 1300-1400 1234567 Hindi 500 140 Moskva RUS VOR
15550 VOICE OF RUSSIA 1400-1500 1234567 Urdu 500 140 Moskva RUS VOR
This situation, with daily variations has been going on for most of a week, and
the Russian transmission authorities have been notified of it. Why in the world
don`t they close down the bad transmitter until and unless they can repair it?
Keeping it on the air certainly does VOR no good as no one would deliberately
listen to it, the programming is duplicated on other frequencies, and while on
the air it interferes with numerous other stations, even other VOR
transmissions! (Glenn Hauser, OK, DX LISTENING DIGEST)
