“Alfons and the Magic Christmas Tree” read by Clayton Howard on HCJB DX Patry Line in December 1974

Many thanks to SWLing Post contributor, Paul Rawdon, who shares the following:

[This is] a recording of a story featured on HCJB’s DX Party Line hosted by Clayton Howard. As far as I remember it was recorded in December 1974. It’s a short story from SPEEDX about the reception of Tristan Da Cunha and St Helena.

SPEEDX ran from 1971 until a declining membership forced its closure in 1995 archived copies of its monthly bulletin can be found here: https://worldradiohistory.com/Speedx.htm
Happy Christmas.

Wow! What a timely contribution! Thank you, Paul and Merry Christmas!

Studio Recording of the KMTS Winter Test Transmission on December 17, 2020

If you missed the KMTS (or is that KTMS?) test broadcast on the 17th of December 2020, you’re in luck. I’ve just discovered a studio recording of the entire broadcast on Soundcloud, via a Post reader tip.

I’ve embedded a Soundcloud audio player below, but you can also listen via Soundcloud:

I’ll admit that this broadcast had a lot of listeners scratching their heads–a bit of a mystery. Reminded me, to some degree, of the Boards Of Canada pirate radio broadcasts some years ago, and the mystery surrounding a BoC album release. Also reminded me on one of my all-time favorite pirate radio stations: Radio Strange Outpost. But, of course, this wasn’t a pirate station.

I know this: I absolutely LOVE the KMTS test broadcast! What fun! Kudos to the producer (or producers)! I’ll add this to the Shortwave Radio Audio Archive. If anyone was able to make a full off-air recording of the broadcast, please contact me and I’ll add that along with the studio recording.

Using the Icom IC-705 to record a local AM broadcast station

In my previous post, I mentioned how much I enjoy the built-in digital audio recorder in the new Icom IC-705. While I wouldn’t buy a QRP transceiver specifically for built-in audio recording–there are less expensive options out there–it is an incredibly useful feature in my world.

After publishing that post, I was reminded that Monday morning (October 12, 2020) I connected the IC-705 to my homebrew Noise-Cancelling Passive Loop antenna mounted indoors at my parents’ house.

My NCPL antenna

Their house is like so many others in that it is inundated with RFI (radio frequency interference). I find that the NCPL antenna does a fine job mitigating most of that noise on the mediumwave band when I position it so that the bulk of the interference is nulled.

Monday morning, I tuned the IC-705 to my favorite local AM station: WAIZ on 630 kHz.

Weekday mornings, Dave and his “Wacky Wake-Up Crew” always put me in the right mood. They’re incredibly goofy/corny and 100% original.

It’s extraordinarily rare these days to find a local radio station, with local talent, creating a local daily radio show. Almost all of their ads are local, too.

I made the following off-air recording for myself, but decided to upload it for others to enjoy. I’m not sure what the receiver audio EQ or bandwidth filter was set to when I recorded this. It’s not a demo of receiver performance, just a little radio fun.

Enjoy:

As I believe this may be of interest to you and your readers here is a link to a collection of recordings I have uploaded to archive.org of Japanese SDR recordings I made over the course of September 2020. I uploaded them as .wav files and archive converts it to .flac and .mp3.

April’s collection of Japanese language WebSDR recordings for July and August 2020

Many thanks to SWLing Post contributor, April TimeLady, who writes:

Please find in this email links to two months of Japanese SDR recordings I have made. One is for July and the other is for August. I have uploaded them to archive.org.  I send you these links because I think it may interest your audience to listen to Japanese language SDR recordings. Nearly all of the domestic broadcast recordings are NHK, specifically the late night program since I like it. Enjoy!

Thank you for sharing your off-air recordings with us, April!

Richard shares recordings of The Buzzer

Many thanks to SWLing Post contributor, Richard Lacroix,

I was intrigued by your post, “The ghostly radio station that no one claims to run (BBC Future)”. I attempted to listening to the station on 4625 kHz from my home location here in Toronto, Ontario Canada but unfortunately could not receive the signal. WebSDR to the rescue. I managed to locate a couple of KiwiSDRs in Russia which yielded great reception of “The Buzzer”.

I figured that some readers may be interested in knowing what the buzzer sounds like. I have therefore included 2 recordings of the broadcast; the first in AM and the second in USB mode with a 3.2 kHz wide filter setting. I am also sharing a screen shot of the waterfall which clearly depicts the signal [see at top of post].

Recordings

The Buzzer recorded July 18, 2020 at 01:07 UTC  on 4625 kHz in AM mode:

The Buzzer recorded July 18, 2020 at 08:26 UTC  on 4625 kHz in upper sideband mode:

Thank you for sharing this, Richard!

Like you, I have difficult receiving The Buzzer from North America (especially in summer conditions with QRN). That’s where KiwiSDRs really come to the rescue. Thanks again for sharing your recordings.

Can you help Carlos identify this 1982 polytone broadcast?

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

I have a tape with a recording I made in 1982 while listening to shortwave.

I’m not really sure if I caught some kind of polytone numbers station. Could you or your readers be able to identify it?

Post readers: If you can help Carlos identify this transmission, please comment!
