Many thanks to SRAA contributor Paul Walker, who shares the following field recordings of the BBC World Service on 9410 kHz made on September 19, 20, and 25, 2025 at 0458 UTC in McGrath, Alaska. Paul notes:

The English feed via Ascension to West Africa operates from 05:00 to 07:00 UTC on several days in late September, featuring something rare: the carrier is switched on, followed by a brief silence and then an interval signal. This sequence occurs every time I hear this transmission sign on, but I have noticed it almost nowhere else on BBC World Service shortwave, which usually just “crash starts” and ends abruptly.
