Radio Free Whatever (Pearl Harbor Tribute): December 15, 2013

For your listening pleasure: one hour, seven minutes of the pirate radio station, Radio Free Whatever.

I recorded this broadcast on December 15 2013, starting around 2:40 UTC, on 6,925 kHz AM. This broadcast was a tribute to WWII and Pearl Harbor and contains news clips and music from the same time period. I believe my recording begins about five or so minutes into their broadcast.

Spectres of Shortwave soundtrack via WRMI: November 13, 2016

The following recording of the Spectres of Shortwave soundtrack was recorded on November 13, 2016 on 7.57 MHz starting around 23:00 UTC. Note that the audio ends abruptly--likely a technical error at WRMI. I kept recording one minute after the audio stopped (but the AM carrier was still present).  

2016 BBC Antarctic Midwinter Broadcast: June 21, 2016

Many thanks to SRAA contributor, Mark Hist, who notes the following:

Thanks for alerting shortwave listeners to the British Antarctic Survey broadcast. It felt very poignant listening to a broadcast aimed at such a small number of people, with the voices of their loved ones being launched around the world.
I was able to record the broadcast from only 100 miles away from the Woofferton transmitter, so needless to say the quality and strength was very good. I imagine hearing that broadcast buried in the noise from far away with those happy birthday songs and best wishes must have been very emotional for its intended audience.
I enclose a short segment from my 30 minute recording, plus a photo (above) taken the next day of my set up (it was dark at the time of the recording).

I also recorded the broadcast from Saint-Anne-de-Beaupré, Québec, Canada. I wrote a post about this on the SWLing Post (click here to read). The following is my recording from 7360 kHz. Reception was not nearly as strong as that of Mark, above:

Note that we collected over 30 recordings--from accross the globe. You can listen to and browse them on the SWLing Post by clicking here.

Rádio Nacional da Amazônia: May 12, 2016 (breaking news of Dilma Rousseff facing impeachment trial)

Last night, my buddy John Figliozzi shared the following tip regarding Rádio Nacional da Amazônia:

Both frequencies active tonight — 6180 and 11780 — with lots of discussion as well as excerpts from speeches in the Brazilian Senate on the impeachment of the President.  All in Portuguese of course.  ID around 0155 with announcement of shortwave frequencies.  Excellent armchair quality signal on 6180; audible with considerable QRN on 11780.

After reading John's message, I immediately tuned to 6180 kHz where Rádio Nacional da Amazônia was quite strong. I recorded almost two hours of their broadcast which includes news about the impeachment and music as well. This recording was made in North Carolina using a WinRadio Excalibur receiver and a Pixel Loop Pro magnetic loop antenna, starting around 02:20 UTC on May 12, 2016:

Recording the 2015 Leap Second via WWV and CHU: June 30, 2015

Yesterday, I posted a brief article about the leap second that occurred between 23:59:59 June 30, 2015 and 00:00:00 UTC July 01, 2015.

I decided to record the leap second on as many shortwave time station frequencies as possible. The only viable options for me--based on time of day and my reception location--were the WWV frequencies 10, 15, 20, and 25 MHz, and CHU frequencies 7,850 and 14,670 kHz.

I was able to monitor four different time station frequencies simultaneously on the TitanSDR Pro. (click to enlarge)

Unfortunately, HF propagation was very poor yesterday, so the higher WWV frequencies--20 and 25 MHz--were completely inaudible, as was CHU on 14,670 kHz. There were numerous thunderstorms in our area, so static crashes were prevalent.

Still, since this was a first attempt to record a "leap second," I didn't want to take any chances.  I had the Titan SDR Pro monitoring and recording two CHU and two WWV frequencies [screenshot], the Elad FDM-S2 recording WWV on 15 MHz [screenshot], and the WinRadio Excalibur on WWV's 10 MHz frequency, as well as recording the whole 31 meter band spectrum [screenshot].

In the end, the strongest frequencies I captured were CHU on 7,850 kHz and WWV on 15,000 kHz. WWV on 10,000 kHz was much weaker than normal and the band was quite noisy--still, it's readable, so I included this recording, too. Recordings follow...

All of the recordings start just before the announcement of 23:59 UTC.

WWV added the extra second and higher tone, then continued with their top of the hour announcements, including a note about leap second (which begins after the 00:04 announcement). CHU's adjustment included a long second tone and period of silence.

One interesting note about the 10 MHz WWV recording above: I believe I may be hearing BPM China in the background. I'm curious if anyone can confirm this because I don't know BPM's cadence/pattern well enough to ID it.
