Many thanks to SRAA contributor Liam Spencer, who shares the following recording and notes:Broadcaster: Polish Radio External Service (Via WRN and WRMI)Date of recording: September 26, 2025Starting time: 02:59 UTCFrequency: 9.455 MHzReception location: Berthoud, Colorado, USAReceiver and antenna: Sihuadon D-808 with telescopic antennaNotes: After the withdrawal of most Overcomer Ministry broadcasts in the Summer of 2025. WRMI began relaying the World Radio Network North American stream to fill the empty hours. While this is great for many shortwave listeners, as we get to hear stations that used to broadcast on shortwave again. WRMI isn't making any money from broadcasting the World Radio Network, and it is unknown how long these will last. On September 26th, I recorded the Polish Radio External Service, as they became part of my daily listening thanks to WRMI. I used a cassette tape to record the broadcast. Sometime during the recording, a few seconds of the broadcast were cut as I had to flip over the tape to continue recording.

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.
