The Buzzer sounds a bit different this evening

The Buzzer (S28) sounds a bit different today, having a higher pitch. This is a recording made today at 1909z, on 4625 kHz, with the receiver in AM mode.

The Buzzer, with "The Swan's Lake" and with an OM counting live!

This is my first post after a long time. My excitement for what's going on motivated me to finally quit my long silence.

The Buzzer (S28) stopped transmitting two days ago. Since then, several people confirmed its absence. Yesterday I found (among with others) that the familiar buzzing sound was back again.

Moments ago (4625 USB, 1834z), I was lucky to hear a test transmission from S28! An OM counting in Russian, then the buzzing sound and "The Swan's Lake"!

Here is the recording! Enjoy!

The web page http://www.uvb-76.net/ has a live feed from 4625 kHz.

Buzzer's other frequency

S28 the "buzzer" or the "foghorn" (OK it sounds like a truck's horn to me!) is using another frequency except 4625 kHz. Ary warned the Enigma 2000 group that S28 can also be found at 3842 kHz.

Here is a comparison of 4625 and 3842 kHz as recorded in USB mode today at 1920z. 3842 is weaker here and lacks the carrier. Also the tones are decaying, not like 4625 kHz.

If you're not convinced if this is S28, listen them both going in "berserk mode" near the hour (1959z). This time the first one recorded is 4625 kHz.

Why "the pip" named S30

Those scanning the low HF bands are familiar with the "piping" sound found on 3757 kHz. The "pip" also transmits on 5448 kHz during the day. Most of the time it pips continuously, exactly as its cousin, the "Buzzer" (S28 or formally UBV76), buzzes, but sometimes it sends a message. Today, on 5448 USB, 1520z a YL sent one in Russian. Listen!

Which is very similar to the XSW (S32) text I heard some time ago!

Thanks Mike!
