Broadcaster: NHK WORLD RADIO JAPAN
Date of recording: 9/5/2017
Starting time: 2130 UTC
Frequency: 17.54 MHz
Location: Southeast Brazil
Receiver and antenna: MORPHY RICHARDS MR 27024 WITH LONG WIRE
Live, off-air recordings of the Voice of Korea broadcasts in English and German on 4 September 2017, beginning at 16:30 on 11645 kHz and 18:30 UTC on 9425 kHz, respectively. The broadcasts were transmitted from Kujang, Democratic People's Republic of Korea (North Korea), with a transmitter power of 200 kW. The English broadcast had an antenna beam direction of 296°, while the German broadcast was at 325°, both directed towards Europe.
The commentaries in the first part of the programs include a discussion of the development of nuclear weapons by the DPRK and the announcement of the recent test of a hydrogen bomb.
Although the Voice of Korea broadcasts are nominally about 57 minutes in duration, the recording of the English broadcast stops after 30 minutes when China Radio International signs on, on an adjacent frequency with a powerful signal overriding that of the Voice of Korea. The recording of the German broadcast begins about 5 minutes late.
The broadcasts were received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in synchronous AM mode with 5.08 kHz total bandwidth RF filtering. Reception of the two broadcasts varied from fair to good with some noise and fading and the German broadcast was accompanied by the sound of jamming, likely originating from the same transmitter plant that is used to jam broadcasts from the Republic of Korea (South Korea), and is likely due to a technical fault.

Many thanks to SRAA contributor, Jack Widner, who shares the following off-air recording and notes:
Radio Bucharest, Romania, on Shortwave New Year's Eve 1989. The beginning is missing. Frequency not logged but was probably 6155 or 11830, time 0200 UTC.
The Ceausescu regime had finally been toppled and executed outside the capital Bucharest. These were heady times; Romania was one of the last of the "Iron curtain" countries to change its Communist government.
But now Ceausescu is out and Romania has its first taste of fresh air. This program reflects that new-found liberalisation. The announcer at 0102 says "FREE Romania" and at 01:12 - 02:33 the American Ambassador Alan Green Jr sends greetings from President GHWB. After that, the majority of the program is traditional music and celebrations of Romanian new year. The two announcers are full of national pride!
There is a slight gap at 11:19 - 11:23. Frequency and contact information are at the end of the program, 25:15.
The picture of Bucharest is the cover of a verification card from 1967 in my possession.
Heard in Pennsylvania, December 1989.
Voice of Korea, DPRK recorded in London, UK on September 3, 2017 at 1338 UTC, on the frequency of 15245 kHz using AirSpy, SpyVerter, SDR# software and a 2 x 6m long wire dipole antenna. The transmitter has a power rating of 200 kW and is located in Kujang, DPRK. North Korea's successful sixth nuclear test is officially announced at 5 minutes, 6 seconds into the recording. Severe jamming can be heard concurrently with the transmission.
Live, off-air, one-and-a-half-hour excerpt of a five-and-a-half-hour recording of Radio Cubana's AM radio station CMBE, Radio Ciudad de la Habana, Havana, Cuba, on 14 August 2017 beginning at 21:00 UTC. The station operates on an frequency of 820 kHz from a transmitter in the Arroyo Arenas area of Havana with a power of 10 kW and an omnidirectional antenna. There is some confusion about the correct current call letters of the station. Government documents state CMBE, while other sources state CMBU. On air, the station uses CMCA and these were the official call letters in the past when the station used a different transmitter site.
The transmission was received on a Tecsun PL-880 receiver with its built-in ferrite-bar-loop antenna in Naples, Florida, in AM mode with 5 kHz RF filtering. Reception was fairly good although the signal is a bit weak initially and there is some atmospheric noise due to thundershowers and thunderstorms in the Naples area. The transmitter went off the air a few seconds before the end of the recording and didn't return for about five minutes.
Radio Ciudad de la Habana, or simply Radio Ciudad, is a youth-oriented radio station with an emphasis on cultural and musical programming.
The recorded programs are "Diario Hablado" and "Rapsodia Latina."
Live, off-air, one-hour recording of AM radio station WJCC, Radio Mega, Miami, on 16 August 2017 beginning at 03:00 UTC (Tuesday, 15 August, 23:00 EDT). The station operates on an expanded-band frequency of 1700 kHz with a transmitter in Hialeah in northwest Miami with a nighttime power of 1 kW and an omnidirectional antenna.
The transmission was received on a Tecsun PL-880 receiver with its built-in ferrite-bar-loop antenna in a hotel room near Miami International Airport in AM mode with 5 kHz RF filtering. Reception was quite good.
Radio Mega is a multicultural station broadcasting primarily in Haitian Creole and French with religious, wellness, and cultural programming with its AM transmitter in Miami and an associated FM network in Haiti.
The recorded program is the "Unity Show" hosted by Soeur Raymonde Pierre.
Many thanks to Shortwave Radio Audio Archive contributor, Colin Anderton, who shares a series of off-air recordings, originally made on reel-to-reel tape, of Radio Moscow in the late 1970s. This is the second recording in this collection. Colin notes:
As a space flight nut, I have many recordings from the 1970s from Radio Moscow. They used to broadcast on the medium wave, and I used to record the news bulletins during some of the space flights.
In particular, there was a period between December 1977 and March 1978 when Soviet cosmonauts first lived aboard the Salyut 6 space station. I recorded each days' news reports on the flights, and also some additional items about them. I have some other flights as well.
I received them all on 227 metres Medium Wave at 22.00 hrs GMT each night. I was in a village called Stetchworth, near Newmarket, Suffolk, England at the time.
In fact, an announcer gives the general daily broadcast details on this first recording.
I used a similar system with all the files, that is: where any edit takes place, I have placed a one-second break to identify the spot. No other editing of any kind has been done.

Two live, off-air, half-hour recordings of the BBC World Service special Antarctic Midwinter Broadcast on 21 June 2017 beginning at 21:30 UTC. The broadcast features special messages and music for the staff of the British Antarctic Survey overwintering in Antarctica.
The first recording is of the transmission on a frequency of 7360 kHz from the BBC's Ascension Island relay station (250 kW transmitter power, antenna beam 207 degrees). The transmission was received on a Tecsun PL-880 receiver with a Tecsun AN-03L 7-metre wire antenna in Hanwell (just outside Fredericton), New Brunswick, Canada, in AM mode with 5 kHz RF filtering. Reception was fairly good with some atmospheric noise.
The second recording is of the transmission on a frequency of 5985 kHz from the BBC's Woofferton, England, transmitting station (300 kW transmitter power, antenna beam 184 degrees). 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 USB mode (to avoid potential adjacent-channel interference) with 2.40 kHz RF filtering. Reception of the broadcast was very good with occasional atmospheric noise.
The program started very slightly late for both transmissions with the first or first two words ("This is") missing.
