Thanks Dragan, test on 14 til 17 Jan only. No reception at nearby
Bucharest and Vienna monitoring, due of dead skip zone. Malmoe files not
so strong than London monitoring.

MOLDOVA/BULGARIA Re: And I wonder what "Sgdra rotation A-31A" means.
This description appears to be slightly messed up. SGD-RA are dipole
arrays on fixed constructions, as opposed to the usual wired curtains.
But Grigoropol has also a rotating antenna that runs on rails. It is being
referred to as PA A30/31. It remains a bit unclear if this is the type
number of this system, A30/31 could also be a specific Grigoriopol
equipment designator.
Here it is:
Of course the system has been placed away from the other installations to
minimize the azimuthal range it can not reach. North of this system are
the other shortwave antennas and transmitters.
It is pretty obvious how the transmitters are placed in two groups. The
first one consisted of three PKV-500 transmitters and went on air in 1973,
the second one with two further PKV-500's followed in 1975. Around 1986/87
two of the transmitters from 1973 have been replaced by new Kondor-1
units, rated at 2000 kW but apparently never run at more than 1000 kW. The
other three transmitters have been upgraded into a 1000 kW variant called
PKV-500-M.
East of the shortwave facilities is the LW/MW complex that went on air
with three Buran model transmitters (1000 kW) in 1971, later followed by a
Shtorm-S (150 kW) that has been moved in from somewhere else. The long row
is the travelling wave antenna (Zarya) for 1548 kHz, the four masts are a
configurable antenna (Kvadrat) that should be in use on 621 kHz. The
"thick" one of the three ND masts is a configurable cage antenna (ARRT)
for 999 kHz. The missing mast was a 350 meters tall antenna (AM-350) for
234 kHz that crashed in 1997, not disrupting an existing service because
234 kHz had been closed down already some years before due to the slow
decline of Radio-1.
Some of the other shortwave equipment: SGD-RA antennas (the closest ones
aiming at South America), background left curtains aiming at North
America, background right the 1973 transmitter complex.
Check out also the Padarsko photos, this is identical equipment:
