Many thanks to SWLing Post contributor, Patrizio Cardelli, who shares the following background story (via our friend, Dave Porter) about a Woofferton test transmission received at his QTH in Italy:


Hi Patrizio,

Thank you for your report and I confirm the details for 9885 kHz are correct. These transmissions were to fault-find on a 250/300 kW sender at the UK HF transmitter station at Woofferton in England.

These duration of these tests can be variable as the engineers can sometimes need a long time to establish a fault or they may interrupt the test, make an adjustment and resume. This is particularly so if the fault is of an intermittent nature.

Encompass Digital Media, Woofferton is the only remaining UK HF sender broadcast station and also is the only one with this transmission test audio and email address.

The audio is contained in a file play-out system and incorporates non-copyright music and voice announcements from one of the engineers, Martin, 2E1EKX at the transmitter site.

There is a Club amateur radio station on site with the callsign M0WOF and the operators are Matt G8XYJ, Dave M0MYA, Gillian M0OVW, John G1JOD and Martin 2E1EKX.

The amateur radio repeater GB3VM that was on site has recently been moved and the history of it is here https://hbrg.co.uk/gb3vm/

Woofferton has recently celebrated 80 years on the air and there was much publicity in the broadcast media.

My son Matt, G8XYJ was the Transmitter Engineer on duty running the 9885 tests.

He features it in the following Youtube video:

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.

Many thanks to SWLing Post contributor, Bill Hemphill (WD9EQD), who shares the following announcement he originally discovered via reddit user fastradioburst23:

Notice of a KTMS winter test transmission beaming to Europe/USA on 9670 kHz at 2300 UTC on 17.12.2020. This transmission will consist of interval jingles, engineer test signals, rare re-media mixes of cult radio favorites, strange tones, and vox. Thank you for your continued attention as the KTMS crew continue working to bring the SWL community unique transmissions.

Thanks for the tip, Bill!

Channel 292 testing new antenna on 9670 kHz

Many thanks to SWLing Post contributor, Harald Kuhl, who shares the following note from Channel 292:

Maybe you already noticed on our homepage, that we try to start using
our new beam on 9670 kHz, which will increase the radiated power to the
target area by more than ten times.

Tests transmissions start today; we are grateful for every reception
report you will send. We change the target area every 15 minutes, so it would
be very helpful, if you could monitor for two hours, when all target areas
would have been covered.

Thanks for the tip, Harald!

Listeners, please send reception reports to Channel 292: [email protected]

KJJR DX Test on Saturday (May 2, 2002)

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

KJJR 880 Whitefish, MT(Kalispell) will test for 1 hour at 10kw non directional Saturday May 2nd 12:01am to 1am mountain time. It will consist of morse code, sweep tones, along with various telephone sound effects

There will be no paper QSL’s issued for this test. Only emailed confirmation. Send an email to [email protected] with “KJJR 880 DX Test” in the email (You MUST put that in that subject line so I don’t accidentally delete it thinking it’s spam!). The reply will likely be a simple email reply with details of the station and confirming the details of what/when you heard it. You WILL get a reply from me in due course, please give me some time!

This is done on short notice and being kept simple as to not burden anyone involved. Thanks to Les Rayburn for creating the test material and Todd Clark for generously offering up the station. I’ve already seen communication between him and the station, asking them to block out an hour from the logs, so he can tinker around with things at the tower site.

Thanks for the heads-up, Paul! Here’s hoping a few MW DXers can log this test.
