Re: bad 7080 outlet. VERY BAD distortion on 15592 to 15672 kHz.
Bad pairs 15064/16256 kHz at 1400 UT, wandering to 15069/16248. On Ham Radio segment 7080; and 6968 kHz. POSITIVE matter: for the first time after long decline of sound quality, I noted Tatar Radio via Samara at 0800-0900 UT on 11925 kHz today Oct 12 with surprisingly HIGH audio quality. No buzz, no distortion, Russian at 0815 UT S=8 signal level. All feeder, tx, and antenna problems now hopefully solved? # # # # The faulty tx / and antenna influence electromagnetic interferences occur at RC-1 Lesnoy Moscow tx site. Mikhail from St.P. sent me this e-mail recently: (...) thank your for your info. Just had a phone talk with of the technicians from Lesnoy transmitting center (Radio Center No.1) about all of these problems (including 7310 kHz spurs). Let's hope they will fix them before their first midday transmission...(...) Mikhail (via wwdxc BC-DX Oct 12) <http://topnews.wwdxc.de> # # # RUSSIA two spurious 7080 and 6968 at 1900-2000 UT, Oct 11. Program Voice of Russia in English. 7080 much stronger at S=9+20 dB level. Nearest regular VoRUS tx in En is 7310 Moscow site. Distortion only on the lower side. No spurious on the upper side like 7425 or 7540 kHz. Also heavy BUZZ again on 7320 kHz German via Samara Russia, 19-20 UT. 73 wb (Oct 11) RUSSIA. Peaks 15610/15640 kHz. A very bad distortion broadcast signal of Voice of Russia Urdu service noted Oct 11; around 1145-1200 UT Warm Up procedure with 800 Hertz test tone into Urdu language broadcast \\ 15405 and 15550 kHz. Broadcast VOR Urdu service, 1200-1300 UT, in \\ tiny 15405 and 15550 kHz outlets. 15610/15640 is NOT scheduled for URDU service. Noted on three rxs like AOR 7030, Eton E1, Sony ICF 2001/2010 73 wb (Wolfgang Bueschel, dxldyg via DX LISTENING DIGEST) WB also notified Mikhail Timofeyev and the Taldom transmitting center about this (gh, DXLD) At 1330 I have the "fundamental" signal on 15605 (listed by HFCC) with somewhat distorted modulation and an FM-like spur on 15640 and scratchy audio up to about 15660. Nothing on the lower side of 15605. (Olle Alm, Sweden, ibid.) Hello, despite I could not determinate the actuator fundamental frequency of the distorted signal, distortion was so tremendous here in Germany, my friend Olle in Sweden noted the signal on the upper flank of the Moscow outlet 15605 kHz today Oct 11. 15605 1300-1530 40,41,49 MSK 500 115 RUS VOR GFC But I noted the distortion already on test tone WARMUP from 1145 UT onwards. 73 wb (Wolfgang Bueschel, ibid.) While the day before, the 15510 area was blotched by a spur from VOR on 15605, as I reported, rechecked Oct 10 at 1356, there was another signal from VOR, which also had a buzz on its carrier, not \\ 15605. Closed with web address, 1359 VOR IS, simultaneous but not synchronized with 15550 and 15605, 1400 ID in Turkish and then just buzz until off at 1401* This is listed in HFCC as Samara, 140 degrees, which doesn't seem right for Turkey: 15510 1200 1600 40-42,49,54,58 SAM 250 140 1234567 250307 281007 D RUS VOR GFC EiBi however says 15510 at 12-14 is for Afghanistan in its languages, but I'm sure I heard 'Burasi Moskva(sp?)'. Axually, this must have been the *start of the Turkish broadcast which per EiBi is supposed to be on other frequencies: 1400 1500 RUS Voice of Russia TU ME 7325a 11985m 1170a 13855m Apparently the spur the day before completely obscured this other VOR transmission. While the dirty spur from VOR was around 15510 on Oct 10, things were different Oct 11: centered on 15640, where the YFR relay is supposed to be, and maybe was anyway, buried under the QRM. At 1306 found this very distorted signal splattering with spikes, worst between 15615 and 15660, ruining Greece on 15630 during talk in unID language, but into non-Christian music at 1311 so decided it was not YFR. Then checking the lower edge of the blob, the modulation obviously matched VOR Hindi service on 15605. But the 15605 transmitter was NOT responsible. The scheduled \\ of 15550 was absent, so I think that was the transmitter to blame, badly mistuned around 15640. Confirming that it was separate from 15605, that frequency went into English at 1400 while 15640 blob did not. This mess was also monitored by Olle Alm in Sweden and Wolfgang Bueschel in Germany all of us off the back if really aimed at India, but very strong here. Wolfgang also notified the Russian transmitter operators about the problem, so we'll see if it's fixed by the next day. There have also been similar problems in the 7.0 MHz area in the European evenings, perhaps from the same faulty unit (Glenn Hauser, OK, DX LISTENING DIGEST) Another spurious pair observed of nominal 15660 kHz VoRUS in English with spurs on 15064/16256 kHz at 1400 UT, wandering to 15069/16248 kHz at 1435 UT.
