Many thanks for sharing this Richard! As it has become a tradition, we will share recordings of the June 21 Midwinter Broadcast to Antarctica here on the SWLing Post once again. Always a highlight of my year!
Hi All,
We received all the transmission here at Rothera.
The midwinters broadcast itself will be transmitted on; 9505 (WOF), 12065(WOF) & 7305(DHA) kHz tomorrow (21st) at 21:30 GMT.
I heard and received the signals of BBC Antarctic Midwinter Broadcast (Test Transmission) on 7305 kHz (ASC) was Very Good but moderate adjacent or nearby frequency interference and on 12065 kHz (WOF) was Very Good signal reception earlier in my area (Philippines).

Hello, I made a reception video with my Tecsun Pl 606 on 9305 khz. It’s with short telescopic antenna. The reception is very good. I live iin N.E. Italy

Here’s what I heard, better signal here from WOF than during the actual broadcast in 2021
ASC (8490km) 7305 kHz
1 by 1
DHA (15,900km) 6035 kHz
Nothing heard
WOF (5160km) 9505 kHz
3 by 3
WOF (5160km) 12065 kHz”
5 by 5
Listening in Ottawa, Canada. Belka DX receiver with 75 foot circumference loop-on-ground antenna. Similar results using XHDATA D808 receiver and same antenna.
PS, this is the strength/readability scale I am using, no true S meter on either receiver. For context the 12065 signal was 30-40 units (FS=100 units) on the Belka.
Signal strength
1. Scarcely perceptible
2. Weak
3. Fairly good
4. Good
5. Very good
Intelligibility
1. Bad
2. Poor
3. Fair
4. Good
5. Excellent
On the Belka: 30 dBuV = S7, 40 dBuV = S9

I am a newbie.

Ascension, Dhabayya, and Woofferton according to the BBC’s page about their Antarctic mid-winter broadcast (https://www.bbc.co.uk/programmes/articles/48Gx2jfJBWHyWggDSD19gFT/antarctic-midwinter-broadcast). I seem to be getting something on 12065 right now, in AM mode, but the other frequencies listed aren’t coming in for me.
