Low Vhf Russian TV Spurious Signals

Startbeitrag von Hugh am 16.02.2014 17:55

Hi

The F2 MUF got to around 45 MHz in Portugal today.
After 10.00 utc there were some Russian TV signals on 40.96-40.98(drifts)

Recorded at 10.48 utc on 40.98,the video buzz and TV sound can be heard mixed together.Note there is always the "chuff chuff" noise with it

43.24 MHz recorded at 10.25 utc...Note that this is 6.5MHz below R1 video carrier frequency.It is clearer 30 seconds or so after the beginning of the recording.

Maybe the old Band 1 transmitters are not getting much maintenance now,normally out of channel signals should be filtered out.

Good DX

Hi,

It's quite strong again in Portugal this morning on 41 MHz at the moment.

Here's a recording,downloadable via "Sizable send"

Sounds like a Russian voiceover of a foreign film to me.

I've filtered out some of the 50 Hz buzz effect

The UKs turn to receive this morning, luckily for me it was strong enough to resolve some weak smeary video. Any clues to the identity or language greatfully received.

@ Hugh and Paul

Great catches! :spos:

Gibt es in Russland keine "Netzagentur", die die Sender überwacht?
Nebenwellen, die so stark sind, dass sie bei Sporadic E bis nach Europa kommen, das geht ja mal gar nicht :D....
Nebenwellen sollten mindestens 80 dB schwächer als der Träger sein...

Great catch !
Is this a sign that not all Band 1 transmitters from IRIB are gone ?

The signal was in again today very briefly in Portugal around 1200 utc.
I cannot tune that low for TV unfortunately.

Sounded like a news programme was just starting.

Before this there was a very "bored" local voiceover of a US TV show.

It is not thought to be from Iran.
