April’s collection of Japanese language WebSDR recordings for October 2020

In this email is a link to recordings I made from Japanese SDRs over the course of October 2020 and have uploaded to archive.org. This is the link:

https://archive.org/details/JPSDROCT2020

The original files are in .wav, archive.org converts them to mp3 and flac. Files with sas in them are supposed to be in stereo. There are many shortwave recordings in it, as well as mediumwave.

For anyone who is hunting IDs, Japanese radio stations definitely announce their full ID at 5 AM Japan Standard Time each day. On the top of the hour commercial radio stations ID. On Mondays between 1 and 2 AM (commonly given as between 25:00 and 26:00 Sundays on Japanese radio schedules) many Japanese radio stations go off the air for transmitter maintenance and give a very full, 5 minute long ID. I believe I have included one that I clipped for 1008 AM in Osaka in this month’s collection; 1008 AM, JONR is definitely in full AM stereo.

A good reference for Japanese AM radio call signs is on MWList at http://www.mwlist.org/mwlist_quick_and_easy.php?area=2

Thank you for reading this, and please take care.

Thank you, April for uploading and sharing your recordings! I’ve enjoyed browsing these each month!

Richard logs shortwave pirates WDOG and Radio Station EFP

Many thanks to SWLing Post contributor, Richard Lacroix, who shares the following:

First off, thank you goes out to John Hudak’s timely post on the ODXA group. Shortly after his post, I was able to quickly tune-in and intercept 2 pirate radio stations on September 5 2020 during the period 00:30 to 02:17 UTC.

John’s post read:

“Pirate station WDOG is on 5060kHz. USB right now as I write this – 0027UTC Sept. 5, 2020 (8:27 p.m. EDT Fri. Sept. 4). Fairly good signal, playing various rock and pop songs. Frequent ID’s between songs and sound of dog barking.”

There were in actuality 2 sequential broadcasts. The first from WDOG on 5060.0 kHz USB from an unconfirmed start time until sign-off with “Star-Spangled Banner” played by Jimi Hendrix at Woodstock at 01:53 UTC.

The second broadcast followed suite by Radio Station EFP, as well on 5060.0 kHz, but this time in AM mode. Radio Station EFP continued to broadcast until approximately 02:17 UTC after which it started to exhibit deep signal path fades and eventually went off-air at 02:17:40 UTC.

Armed with the combination of devoted listeners posting reception reports and a radio always at the ready, this made for a very exciting 2 hours of SWL.

Included is a 10 minute audio compilation for everyone to enjoy which I stitched together from the 2 plus hours of off-air broadcast recording I saved:

This is brilliant, Richard! Thank you so much for sharing your notes and recording.

I haven’t done nearly enough pirate radio listening this summer. Your timely report reminds me it’s time to change that! Arrrrr!

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!

August 2020 recordings

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

Tom’s amazing 1986 Voyager Experimental Aircraft flight communications recording and QSL card

One of the most amazing things about hosting and curating a massive collection of shortwave radio recordings is listening to each recording as they’re published on the Shortwave Radio Audio Archive (SRAA).

SRAA contributor, Tom Gavaras, has shared some brilliant off-air and studio recordings over the years including the following shortwave recording of Voyager Experimental Aircraft flight communications with Dick Rutan and Jeana Yeager in 1986.

I haven’t even published the recording on the archive yet, as he just submitted it. Tom notes:

Rutan Model 76 Voyager Experimental Aircraft was the first aircraft to fly around the world without stopping or refueling.

It was piloted by Dick Rutan and Jeana Yeager.

The flight took off from Edwards Air Force Base’s runway in the Mojave Desert on December 14, 1986, and ended 9 days later on December 23, setting a flight endurance record.

This shortwave recording is a sample of some of the communications between Dick Rutan and his ground crew including a debate if Dick should walk out of the aircraft after it lands.

Tom made this recording with an ICOM R71A receiver in Minnetonka, MN, and believes the date of this recording is December 22, 1986:

QSL card

This is simply amazing, Tom! Thank you so much for sharing your recording and QSL card with us. A proper radio treasure!

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.

April’s collection of Japanese language WebSDR recordings for June 2020

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

This is a collection of SDR recordings made of Japanese language radio stations for June 2020.” It may be useful to note that I had encoded them at .ogg from .wav, and archive.org automatically converts audio to .mp3 format. The great majority of the recordings are from NHK JOAK Tokyo; I have reason to believe that it broadcasts in AM Stereo. Those recordings with “sas” in the filename are in stereophonic sound, or supposed to be at least. I am unsure if what I hear are artefacts of skywave or AM interference or actually stereo, but it seems to be so when I listen to the playback of such files. The English language Wikipedia article on AM stereo is definitely not complete when it comes to Japanese radio stations, and there does not seem to be a corresponding article on the Japanese Wikipedia..
