[Spooks] UVB-76 Buzzer experiencing outage

[Ryan Kirby]

The counting around that time (which is when I first picked it up 2pm
Eastern = ~ 6pm zulu) was definitely synthesized male. It actually
started with a synthesized female counting first 1-0, then 1-10.
Followed by the Swan Lake, buzzer, etc.
This I believe to possibly be genuine. Since it was only up for a
brief time. There was very obvious modulation on the carrier before it
went live, which would be indicative of testing or maintenance like we
as assuming is going on there. However, the pirate activity has me
questioning everything.

The morse code was absolutely from a pirate. I decoded a lot of the
higher hz morse
It said "Fuck You Ryan" twice
followed by "Good Night Ary" in dutch
There were a few parts I was not sure of "??? My mother copied ????"
and "???K you in morse"
As well as various "UVB76" and "AVB76" mentions within the morse.
The lower portions of morse were 5character groupings of no obvious
pattern or meaning.

These transmissions were during the time myself and Ary were sending
emails regarding the recent fluctuations in broadcast, and are
obviously not a coincidence.

I monitored 4.625 MHz until roughly 6:30-7:70pm est. (~14-1500 zulu).
Nothing further could be heard on the frequency other than random
morse (assuming from pirates).
Currently, same carrier and modulation can be heard as what was
occurring on 01SEP2010. On Upper Side Band it almost sounds like data
transmission but is clearly not (some type of modulation or RFI, or
both).

I believe what you initially observed (minus pirate broadcasts of
morse and music) were a propagation test due to local time of
broadcast (nearly 2200 moscow time) and what was being broadcast.
