Experimental Station KC2XIO: Circa 1971
Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:
KC2XIO was an experimental radio station operated by the National Bureau of Standards in Boulder, Colorado between July 1970 and May 1971. This was to gather information in preparation of the format change for WWV and WWVH which happened in July 1971. Here are two recordings of their voice announcement (one male and one female) as heard in Ancaster, Ontario, Canada on a Hallicrafters S-52 receiver that was hooked up to an outdoor longwire antenna. The frequency used for these test transmissions was 13560 kHz shortwave.
Reception location: Ancaster, Ontario, Canada
Receiver and antenna: Hallicrafters S-52 using a longwire antenna

BBC World Service Annual Antarctic Midwinter Broadcast: June 21, 2023
A live, off-air, half-hour recording of the BBC World Service special Antarctic Midwinter Broadcast on 21 June 2023 beginning at 21:30 UTC. The broadcast, hosted by Cerys Matthews, featured messages and music for the 37 members of the staff of the British Antarctic Survey (BAS) overwintering in Antarctica at the Rothera (Antarctic Peninsula) and King Edward Point and Bird Island (South Georgia) research stations. In addition to personal messages from family and friends, there were interviews withProfessor Dame Jane Francis, Director of BAS and Nadia Frontier, a marine biologist from BAS and former winterer. The transmitter came on the air with a test tone (1108 Hz plus harmonics) about a minute before the program started. As sometimes happens, the first few words of the introduction were missed.
The recording is of the transmission first on a frequency of 12005 kHz but after a few minutes it was switched to 13810 kHz due to interference (QRM) on the former frequency. Both frequencies were from the BBC's Woofferton, England, transmitting station. The sender of the 12005 kHz frequency had a registered power of 300 kW with antenna beam 182 degrees, while that for 13810 kHz was registered as 250 kW with an antenna beam of180 degrees. The transmission was received on a Tecsun PL-880 receiver with a Tecsun AN-03L 7-metre wire antenna outdoors in Hanwell (just outside Fredericton), New Brunswick, Canada, in AM mode with 2.3 kHz RF filtering. Reception on 13810 kHz was quite good with little noise or fading and very good signal strength. The additional parallel frequency of 7255 kHz from Dhabbaya, United Arab Emirates was not heard.

Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:
Broadcaster: Radio Togo, Lome circa 1973
Frequency: 5.047 MHz
Reception location: Ancaster, Ontario, Canada
Receiver and antenna: Realistic DX-150A with a long wire antenna
Notes: In the early 1970's, Radio Togo from Lome was often the strongest African signal on the 60 metre shortwave band. They could be heard here best in southern Ontario, Canada around 0530 UTC sign on, or around sign off at 2300 hours UTC, on their longtime frequency of 5047 kHz. Programming was mostly in French and identification could be given differently, such as Radiodiffusion du Togo or Radiodiffusion-Television Togolaise. Here are two recordings circa 1973, one at sign on with interval signal and anthem, the other at sign off.

RTL Longwave End of Broadcasting: January 1, 2023
RTL longwave antenna array at Beidweiler, Luxembourg
Live off-air recording of the last approximately two hours of programming from the RTL longwave station on 1 January 2023 beginning at 22:00 UTC on the frequency of 234 kHz. The signal originated from a transmitter located in Beidweiler, Luxembourg, reported to operate with a power of 375 kW at night (and 750 kW during the day). The transmitter was capable of operating at 1500 kW. The three-mast antenna beamed the signal mostly in the direction of Paris.
RTL is a general-interest, news, talk, and music station station owned by the RTL Group with its main studios in Paris. It has an extensive FM network covering France and also uses other broadcasting means such as DAB+ and streaming services.
The final two hours of programming was produced and presented by long-time French broadcaster Georges Lang, a devotee of English-language rock, pop, and blues music primarily from the 1960s through the 1980s. The first hour was a special New Year's version of the "Georges Lang Collection" followed by "Les Nocturnes," a program Lang has done for fifty years. The transmitter left the air at 00:00:05 UTC.
The broadcast was received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in AM mode with 9.00 kHz RF filtering. Reception was excellent.
