Radio Verdad, Chiquimula, Guatemala is quite a regular catch at home, however, their modulation is nearly always weak as the carrier struggles to lift above the ubiquitous blanket of local QRM. Another issue with hearing this station is the digital utility signal just above 4055 kHz, thus requiring LSB reception to reject the adjacent noise.
This particular recording of Radio Verdad was taken during a DX’pedition using the 200 metre longwire and is unprecedented in signal strength and clarity – in my personal experience. With fully discernible audio both the Elad FDM DUO and Sony ICF-2001D receivers perform very well with my experimental 200 metre antenna. I should point out that the audio from the Sony is significantly louder because the speaker on the Elad is puny, to say the least. However, the reception on the Elad sounds to me at least, superior to the Sony in terms of SNR, which is everything in Tropical Band DXing. As usual, I welcome your comments. Recorded in Oxford UK on 31/07/18 at 03:31 hrs UTC. Thanks for watching.

Hi there, I thought I would share my first reception of Radio Tawantinsuyo, from Cusco, Peru, recorded during the inaugural test of my 200 metre longwire antenna. Of course this particular reception could be coincidence, but a very welcome catch in any case. Once again, the Sony ICF-2001D performs very well with this large antenna, but as on previous occasions, the rule is always to ‘choose your battles well’ targeting weak DX signals in uncrowded areas of the Tropical Band and elsewhere on shortwave. More details on the longwire antenna to follow in another post. Recorded at the ‘DX woods’ in Oxfordshire, UK on 31/07/16 at 00:27 hrs UTC. Thanks for watching.

On Tuesday, 21 June 2016, the BBC World Service officially transmitted the 2016 BBC Antarctic Midwinter Broadcast–an international radio broadcast intended for a small group of scientists, technicians, and support staff who work for the British Antarctic Survey.
This is one of my favorite annual broadcasts, and I endeavor to listen every year. Once again, the SWLing Post called upon readers to make a short recording of the broadcast from their locale.
Below are the entries, roughly organized by continent and country/region, including reader’s photos if provided. I had planned to post these recordings by Sunday, but my travels interfered and I discovered an additional ten recordings in my inbox! (If I’ve somehow missed including your entry, please contact me; I’ll amend this post.)
So, without further ado….

Poland
SWL: Chris Ditrich Location: Poland Notes: Reception on 5985 kHz and 7360 kHz was very good 59 – 58, however reception on 6035 kHz was not that good, signal was there but not much readable
SWL: Dmitry Elagin Location: Saratov, Russia Notes: I accepted BBC Antarctic Midwinter Broadcast in Saratov, Russia. I made video record by means of my SDRPlay.
SWL: Chris Inwood Location: Conrwall, England Notes: [R]ecorded on 5.985 MHz. This frequency was by far the best quality. I was able to copy 7.365 here but there was slight QSB and some interference from an adjacent broadcaster HCJB. 6.035 was not heard at all neither was 9.720 MHz. Very best wishes and thanks, I always look forward to my email.
SWL: Mark Hirst Location: Basingstoke, Hampshire Notes: 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.
My recording location was Basingstoke, Hampshire in the UK – locator IO91LH 20HH
[Note that Mark also recorded the full 30 minute broadcast which you can download by clicking here.]
SWL: Dean Allison Location: Bedlington, Northumberland, England Notes: I have attached an audio file of the BBC transmission to Antarctica. My location is Bedlington, Northumberland, England, about 100 feet above sea level, using a Kenwood R5000 receiver and a 30 feet longwire antenna about 12 feet off the ground. This was the 5985 kHz transmission.
SWL: Jerry Rhys Location: Surrey, England Notes: Attached are two recordings of today’s BBC Antarctic Broadcast made between
2130 and 2150z. The first recording was made using AM mode with 8 kHz bandwidth on 5985 then 7360, followed by 6035. The second recording was made using SAM mode with 10 kHz bandwidth on 7360, 6035, and 5985.
The best signal was on 5985, 7360 was weak but readable, on 6035 I could detect a carrier and occasional modulation – on this frequency there was also interference from a digital transmission on 6037. Nothing heard on 9720.
I was using a RF Space SDR-IQ Receiver, and a Wellbrook ALA1530S Loop
Antenna installed in my loft. Many thanks for the SWLing Post, always an enjoyable read!
SWL: Alan (G4TMV) Location: northern England Notes: Reception of this special broadcast was excellent here in northern England on 5985 kHz. It was an enjoyable broadcast again, but Babcock weren’t wasting any electricity on it, it came on and went off again almost spot on 2130 and 2200!
SWL: Dom B Location: Newcastle Under Lyme, England Notes: I live streamed the midwinter broadcast on my Tecsun PL-380 from my location in Newcastle Under Lyme in the UK
SWL: Lawrence Beedle Location: Manchester, England Notes: Here is my recording of the mid winter broadcast by the BBC 21st June 2016. Tecsun PL660 telescopic aerial, indoors, sat at kitchen table in a house in Manchester, England, UK. 5985khz good reception. 6035 kHz not as strong, 7360 kHz no reception. Recorded on iPhone next to speaker on radio. 36 seconds.
SWL: David Mappin Location: Filey, England Notes: Just thought I would let you know how I got on with the BBC WS broadcast to Antarctica. I used my Icom IC-R75 receiver and a Wellbrook ALA1530 inside the house. 5985 kHz was very strong with me here on the east coast of the UK (NVIS propagation?). Nothing heard on 6035 or 9720 but a weak signal on 7360. Attached (above) is a photograph of my listening post. This is a link to a YouTube video of the start of the broadcast. My very best regards and thank you for your excellent website.

A screenshot from Cap’s Elad FDM-S1 SDR.
SWL: Cap Location: N.W. Scotland Notes: Here is my attempt last night with SDR screenshot attached, Elad FDM-S1 with homebrew mini Mag Loop (<250mm dia) sitting on my bookcase. No doubt there will be better signals/recordings than mine as the signal was really strong from WOF and considering my setup is 100% indoors, it came out ok. External antennas don’t last here as I am by the sea and regular 100mph+ storms in the winter is too much hassle.
SWL: Richard Langley Location: New Brunswick Notes: Tecsun PL-880 receiver with a Tecsun AN-03L 7-metre wire antenna in AM mode with 5.0 kHz RF filtering at the back of my yard. The photo [of Richard’s outdoor portable listening post] was taken during some other recordings last year.

SWL: Thomas Witherspoon Location: Saint-Anne-de-Beaupré, Québec Notes: I traveled to an RFI quite spot in the parking lot of the Basilica in St.-Anne-de-Beaupré, Québec. Click here to read a full post about my set-up and conditions. Note that I used a Sony ICF-SW55 receiver (above), perched on top of my vehicle and tuned to 7360 kHz.
SWL: Dan Hawkins Location: Davis, California Notes:Here is my YouTube video. I’m using both the Sangean and Hammarlund receivers to hunt down the BBC Midwinter Antarctic Broadcast. Probably a somewhat different result than on most of the videos, but probably typical of West Coast propagation at these frequencies and times.

SWL: Nace Magner Location: Bowling Green, Kentucky Notes: Please find attached a video of my reception of the BBC broadcast. Unfortunately, a thunderstorm passed through about 10 minutes prior to the video and the audio is dominated by lightning-related crashes. However, the BBC signal can be heard periodically. My location was on a university campus in Bowling Green, Kentucky, which is about 50 miles north of Nashville, Tennessee. I received the signal using a Tecsun PL-660 and its whip antenna. I enjoy the SWLing site. Best regards, Nace Magner (KW4LY)
Once again, many thanks to all of you who submitted your recordings of the BBC Midwinter Broadcast! We’ll be sharing this post with both the British Antarctic Survey and the BBC World Service. And to all of you, from the SWLing Post: Happy Midwinter! Happy Summer/Winter Solstice!
No seasoned shortwave DXer can forget one of the most distinctive interval signals ever–the “barnyard animals” which marked the beginning of the broadcast day of Radio Botswana, Gaborone, for decades.
On its long-time frequency of 4820 kHz, Botswana was an occasional catch for me from the Seattle USA area. I yearned for clearer, more reliable reception of this station and other Africans which my East Coast USA DXer pals enjoyed!
Zebras mingle with other animals at Chobe National Park, Botswana.
It was always fun–and a DXing challenge–to catch Radio Botswana’s interval signal and sign-on announcements, but it was typically mid winter for reception in Seattle. Propagation on 60 meters needed to be favorable to enjoy anything other than a weak, barely listenable signal. Imagine my surprise and excitement when on the evening of December 27, 1987 I came upon the following signal booming in on 4820 kHz, far, FAR better than any previous Botswana reception. Indeed, their signal that evening surpassed in clarity even the Papua New Guinea and Indonesian “regulars” I would hear on the tropical bands from the Northwest USA.
This recording begins with the famous barnyard animals interval, the beautiful Botswana national anthem (Fatshe leno la rona, or This is Our Land in English) and is followed by a full list of broadcasting frequencies and times in English and the (presumed) Setswana language. That information is followed by a flute instrumental version of the Christian hymn Beautiful Savior, which introduces a short devotional or scripture message. The 10 minute recording wraps up with an a cappella children’s choir.
Great Circle route from the Gaborone transmitter to Seattle receiver location.
My receiving setup for this 1987 recording was an ICOM IC-R70 and a 300 foot long random wire antenna. Such a long antenna is unusual for the middle of an urban area, but I took advantage of living in a 3rd floor apartment across from a small city park. One midweek day, while most folks were at work, I managed to string out this long antenna with very small diameter braided steel wire from the 3rd floor apartment balcony to a distant treetop. This “sloper” antenna had significant directivity to the northeast, which happens to be the bearing for many African stations heard from the Pacific Northwest USA. The small diameter wire was suspended so high that it was virtually invisible from ground level.
Antenna orientation for 1987 reception of Radio Botswana. I’m sure this urban location is plagued by QRM and radio frequency interference now in 2016! My ICOM IC-R70 receiver handled the strong signals from nearby MW & FM broadcasters surprisingly well with the addition of a Grove Tun3 Mini-tuner preselector.
I continued to log Radio Botswana occasionally on 60 meters until the station eventually left the air (early 2000s I think), but I never heard them again with such a strong, clear signal as in late December 1987!

We’ve just posted yet another excellent recording by Tom Laskowski to the Shortwave Radio Audio Archive. I thought a number of Post readers might appreciate this one.
Tom notes:
KNLS – Anchor Point, Alaska, from what I believe is a test transmission on August 1, 1983. According to Wikipedia, KNLS signed on the air July 23, 1983. The program consists of the sign-on ID in English and Russian then is mostly a mix of Big Band music. This recording is 31 minutes long.
Tom’s receiver was a Sony ICF-2001 and he started recording at 09:00 UTC on 11.820 MHz. His location, at the time, was South Bend, Indiana (USA).
Many thanks to SWLing Post contributor, Paul Walker, who shares the following recordings of Radio Vanuatu and the Solomon Islands Broadcasting. Paul lives in Galena, Alaska, and records most of these broadcasts outside of his broadcasting studio:
3945 is much weaker then 7260 for some reason and Nikkei is on that channel till 0900 UTC, so about the only chance I have of hearing Vanuatu on 3945 CLEARLY is when Nikkei signs off.
Thanks for sharing your recordings, Paul! You’ve certainly done a fine job DXing in the northern latitudes all while standing next to a broadcast station.
Last night at about 00:10 UTC, I was pleased to hear the interval signal of one of my favorite pirate radio stations: Radio Casablanca.
“Rick Blaine” fired up his AM transmitter and pumped out some amazing WWII era music on 6,940 kHz for about one hour and a half. Radio Casablanca only pops up a few times a year, so I always feel fortunate to grab the broadcast (click here to listen to previous recordings).
Signal strength varied over the course of the broadcast and the bands were quite noisy–still, the Casablanca signal punched through quite well at times.
Close your eyes and imagine what it must have been like to hear the great bands of the era over the shortwaves…
Radio Verdad, Chiquimula, Guatemala is quite a regular catch at home, however, their modulation is nearly always weak as the carrier struggles to lift above the ubiquitous blanket of local QRM. Another issue with hearing this station is the digital utility signal just above 4055 kHz, thus requiring LSB reception to reject the adjacent noise.
