ANTARCTICA {non} Only a small contribution on this special
solstice Antarctic midwinter radio transmission.

600 Ohm. Unfortunately I got a personal phone call at 21.35 UT.
It was necessary to interrupt my monitoring.
So I heard only these 7 minutes tonight:

21.29:05 UT June 21
switch on at ENC Woofferton bcast center on 12065 kHz,
heard some 1010 Hertz test tone procedure crash start.

21.30:10 UT BBC program start.

I switched-in to two Kiwi units at Sao Paulo Brazil in \\
played with the different AGC slider,
one on 9505 kHz later switched to 7305 kHz from Ascension,

and at 21.28 UT the best SDR audio noted on 12065 kHz channel.

12065 kHz S=9+35dB or -41dBm in Sao Paulo Brazil,

and more poor at Sao Paulo
9505 kHz S=9+20dB or -55dBm (Poor muffled audio tone,
like from a watering can,
ancient micro)
7305 kHz S=9+10dB or -62dBm I guess much much better audio
modulation downunder in the
Antarctic station though)

When tuned – out from 7305 to 7320 kHz upper sideband,
there at Sao Paulo SDR remotedly was a main power scratched
audio noise from the neighbourhood,
underneath … man made noise surrounded.

CUBA next to the Brazilian wander-shift 9673v stn,
noted two Bejucal RHC Spanish outlets at

22.45 to 23.07 UT on June 21:
9535even exact aligned 100 kW TX unit at Bejucal
towards MEX to EQA Latin AM western flank.
What happened ? – bad audio, and seen visible
13 x audio strings (+5 minor strings too) either sideband,
up to 2.1 kHz away distance either side.
50, 120, 200, 250, 300, 350 … Hertz audio tone distance
mixture of 50 and 60 Hertz main power ?

Surprise at 22.58 UT noted the other RHC on exact 9640 Khz,
but next check at 23.04 UT was on \\ 9710 kHz the 50 kW unit
towards Antilles and Suriname, Guyana etc.
