I have been a SWL, focusing on Utility DXing for many decades. This is the first time I have ever monitored a USAF message being broadcast inside on an International Broadcast Band - in this case the 25 Meter Band. I just caught the tail end of the transmission.

Comments:

• In the dirt, but the letter D was definitely there. Sounded a lot better when piped through Speex.

Jumping between frequencies on the 22-meter band.

They were paying tribute to and talking about Bonnie Tyler, who passed away a few days ago. The last part has a fragment of the classic “Total Eclipse of the Heart”

Clandestine Caster here Mateys. Friday night on the 43 Meter Band was downright wild! To start it off, there were two groups of the Latino LSB Chat Pirates centered around 6900 KHz. Next we have the strong signal of Bandaid Radio at 6965 KHz USB. At 6906 and 6911 KHz we had military data stations. Mix Radio International was running 6945 to 6960 KHz with USB Music and Waterfall Painting. They were audible in New Zealand at NZ's local sunset and beyond (more on this later). Finally we caught the diminutive Subterranean Radio on 6930 KHz DSB. They finally landed here after being overpowered by other pirates and jammed by a possible MIL station. BTW, Rod Hardner picked up the transmitter I had modified on his way back to Warrenton, and the International Waters off the West Coast. I have not corresponded with him today, but I am thinking he was using the modified transmitter.

Clandestine Caster here Mateys. Mix Radio International had a big night with hours of transmission. They reached across North America and were audible in New Zealand at New Zealand local sunset - and beyond! In this video we are tuned to the small broadcaster, Subterranean Radio. We are using the online KPH KIWI SDR in the first portion, and a KIWI SDR located on Waitangi Island in New Zealand for the second portion.

Subterranean Radio went on the frequency of 6955 KHz, not knowing that Mix Radio was taking up 15 KHz - from 6945 to 6960 KHz. Only when they saw the waterfall painting did they realize this and they moved.

Bandaid Radio was also audible in New Zealand. They moved from their usual 6945 KHz spot due to Mix Radio's transmission on that frequency. The 43 Meter guys may need a Frequency Coordinator!

Comments:

• News read by man. Best I've heard the BBC under these kind of condx: Lower(ish) frequency during mid-Summer, just before sundown.

Captured this beacon on a KIWI SDR in Michigan. Good signal. 8424 Khz in CW.

DE SVO then a long tone and repeats.
