Many thanks to SWLing Post contributor, Richard Langley, who follows up with the following information about the 2021 Midwinter Broadcast to Antarctica:

As usual, there was a test of this year’s possible frequencies yesterday (14 June) from 21:30 to 21:45 UTC.

They were:

• • 6035 kHz from Dhabbaya
  • 6170 kHz from Ascension
  • 7305 kHz from Woofferton
  • 9505 kHz from Woofferton

As has been the case in past years, three of these frequencies will be chosen for the actual broadcast. Here in NB yesterday, good signals were received on 6170, 7305, and 9505 kHz. 6035 kHz was not heard.

Thank you for sharing this, Richard!
