Re: The Buzzer radio signal
Yep, definitely no shortage of buzz. I don't suppose it does QSL cards, even if it had a known address. More like "Your name will also go on the list"....

Re: The Buzzer radio signal
Hell, no! If you really want to recreate the past, I know someone who still has the [horribly expensive to the taxpayer] software he developed in the 1980s to simulate the DUGA-3 'Russian Woodpecker''s multi-Megawatt pulses in order to test various HF receivers and data-transmission gear of the era.
Alas the one-off deeply-strange ECL hardware and AMD2901-based bit-slice computer [which occupied two Eurocard chassis and had a GEC 4190D minicomputer as its control-head] is no longer in existence. |

Re: The Buzzer radio signal
I liked 'jingle bells' It made topband so much friendlier.

Re: The Buzzer radio signal
Don't forget GEE. I recall the one at Worth Matravers which had a pulse ERP of around 100KW on 30.7 Mc/s. It spread all across the band - but at least it was a good calibration source!

Re: The Buzzer radio signal
Sub Loran is still chirping away on 100 Kilocylcles never heard it on the HF. Bands but have known it on long wave for years

Re: The Buzzer radio signal
Whilst tuning into The Buzzer the other night on 4625kHz (as above), I chanced upon a station calling itself Mystery 21 on 4700kHz, proclaiming "1.2kW into an inverted-V from Central Europe". Reception was pretty good, considering, on a trusty Eddystone 750.They even asked for reception reports. If you miss that merry evening/night-time cacophony of schlagermusik and Euro-rock that used to typify the 49m band, then this made a pleasant interlude.

Re: The Buzzer radio signal
I received that pirate here last night, quite strong but with deep fading. I sent them q reception report. The Buzzer is always strong here at night.

Re: The Buzzer radio signal
I tuned to the buzzer on Wednesday night it sounds a bit different, now with what sounds like a higher pitched noise then instantly into the buzz. I'm not sure if it's all from the same site or two overlapping transmissions. I've not heard it myself but apparently now it's also on 7.0 Mc/s I might have a look for it tonight.

I know you said that the hardware doesn't exist, but even seeing the code would be neat. And emulation is making leaps and bounds these days... |

http://websdr.ru/ There is a signal that fills the latter part of the gap between each buzz, at first I through it was an AGC recovery artifact. The "ghost" signal is about an S point down on the main at its strongest, but it has much more QSB suggesting it is eliminating from a separate location.

Re: The Buzzer radio signal
Thanks Rambo.

Re: The Buzzer radio signal
Unfortunately, Wikipedia's entry on "UVB-76" seems as conjectural and anecdotal as anything else out there, but there's a few points of interest to digest. I had heard a suggestion that the modulation had been chosen to make it as off-putting as possible for human beings to monitor for any length of time!
