I was intrigued by your post, “The ghostly radio station that no one claims to run (BBC Future)”. I attempted to listening to the station on 4625 kHz from my home location here in Toronto, Ontario Canada but unfortunately could not receive the signal. WebSDR to the rescue. I managed to locate a couple of KiwiSDRs in Russia which yielded great reception of “The Buzzer”.
I figured that some readers may be interested in knowing what the buzzer sounds like. I have therefore included 2 recordings of the broadcast; the first in AM and the second in USB mode with a 3.2 kHz wide filter setting. I am also sharing a screen shot of the waterfall which clearly depicts the signal [see at top of post].
The Buzzer recorded July 18, 2020 at 01:07 UTC on 4625 kHz in AM mode:
The Buzzer recorded July 18, 2020 at 08:26 UTC on 4625 kHz in upper sideband mode:
Thank you for sharing this, Richard!
Like you, I have difficult receiving The Buzzer from North America (especially in summer conditions with QRN). That’s where KiwiSDRs really come to the rescue. Thanks again for sharing your recordings.
