More exotic reception 19 Jul 2017

Post by daveB » 30 Jul 2017 23:44

Trawling through the recordings from 19 July 2017 is producing more double hop stations.

I have a very clear id on 66.20 MHz for Radio Rossii at 0929 - the distinctive music and YL announcing "Radio Rossii". Marginal (but good enough to confirm) signals on 68.36 and 68.51 have the same programming. These three frequencies are all used by GTRK Kuban so the transmitters would be:

66.20 - Tblisskya 17 kw 2939 km / 87 deg
68.36 - Kanevskaya - 17 kw 2831 km / 87 deg
68.51 - Armavir 17 kw 3038 km / 87 deg

Next:
66.77 - Ipatova 17 kw 3085 km / 87 deg GKTR Stavropolye
69.53 - Stavropolye 17 kw 3084 kw / 87 deg GKTR Stavropolye - 0930 a snatch of R Rossii's tune and the deep male voice "...Rossii"

The latter two are very marginal and are pushing the limits of SDR demodulation - it took a lot of tweaking to get the "Rossii" bit clear enough on 69.53 to be sure. But the general pattern is a very weak bunch of signals on a bearing of 87 deg and at 2800 - 3100 km.

In the past I've had better reception and on the hour the full id sequence includes the YL id a minute before the hour and the male voice id on the hour with the pips. This time the reception was too marginal to say whether there was a complete sequence or not.

Further up the band on 70.30 I found this weak signal - needing a 60 kHz bandwidth to bring it up. Once again it is a "turkish/arabic" suggesting a "stan". It is not the same programme as the clip I posted 67.04 MHz - which at this time had ululating singing.

The signals come and go but both signals on 67.04 and 70.30 do not have a voice id at 0929 (YL) or at 0930 (OM) - the programmes are unbroken. Is this typical of regional programming in Russia that some will have an id at 30 minutes past the hour and others do not. Victor via the other forum has said 67.04 is from the Dagestan region - i.e. the Kochubey tx at 3439 km / 85 deg

And to slip one more in - which I would suggest is an unlisted transmitter from somewhere -

So once again if anyone has any ideas .... thanks

Victor has identified the tx on 70.7 - actually 70.31 - as R. Rossii from Cherkessk/RTPS which is as 3142 km / 88 deg. And going back over the recording I found a trace of carrier and a snatch of audio at the same time on 72.11 which would be R. Mayak but too weak to consider logging.
