Radio World: John Kean Examines Modern AM Interference Challenges

Leave a reply

Many thanks to SWLing Post contributors Dennis Dura and Frank Howell for sharing this article from Radio?World, which examines the persistent and growing problem of AM?band interference. In “John?Kean Explores AM Interference Issues,” Kean outlines how noise from switching power supplies, urban clutter and even future EV wireless-charging technology are threatening reception quality for AM broadcasters — and offers pathways for engineers and regulators to maintain AM viability.

Greetings all SWLing Post community, here’s more about what the Imaginary Stations crew will be sending up to the ionosphere this week. On Saturday 25th October 2025 at 1100 hrs UTC on 6160 kHz and then again on Sunday 26th October 2025 at 0900/1300 hrs UTC on 6160 kHz and at 2100 UTC on 3975 kHz and 6160 kHz, we’ll be bringing you a telephone tribute via the shortwaves called Skybird Telegraph & Telephone Co. 

There will be lots of phone related tunes, a shortwave first in a live on-air attempt of trying to break the world record of ripping two telephone directories at the same time and an interview with someone who used to say “thank you” to the speaking clock (*subject to availability and if our phone lines are working). Tune in and join us in a celebration of the “dog and bone” (as it’s known in cockney rhythming slang).

On Wednesday 29th October 2025 at 0200 UTC via WRMI  we bring you another Ancient Analogue Archive.  This is the show where we dig deep into forgotten music on archive.org). Expect all sorts of everything (and more).

More on Skybird Telegraph & Telephone Co. below:

November 2025 Schedule Updates: From the Isle of Music & Uncle Bill’s Melting Pot

1 Reply

Many thanks to SWLing Post contributor, Bill Tilford, who shares the following update:

The semiannual time and season changes always bring challenges to FTIOM and UBMP on 6070 and 9670, and we will be pausing our shows on those two frequencies for a month or two until things sort themselves out.  We will have two transmissions of each show on 3955 on Radio Channel 292 from Germany during the interim as follows:

From the Isle of Music

November’s show will feature some Cuban music recordings that entered the Latin and regular GRAMMY competitions this year (it will be too soon to tell if any of them won either.)
Friday, November 14:
3955 kHz at 1700 UTC, repeats 2200 UTC

Uncle Bill’s Melting Pot

November’s show will be a polka party featuring Polish-American bands from the northeast US and Chicago. If you think you don’t like polkas, you just haven’t listened to the right bands.
Friday, November 21:
3955 kHz at 1700 UTC, repeats 2200 UTC

In addition to direct radio reception, we do honor reception reports using remote SDRs as long as the whole program is described and which SDR is specified. All QSLs are e-QSLs only.

Thanks for all you do for radio. Contrary to what some its critics are fond of chanting, shortwave can still be a voice of and for peace, and in these times, that is more important than ever.

Many thanks to SWLing Post contributor Fred Waterer who shares this article from Radio World that takes a closer look at how online SDR networks have transformed shortwave listening. Even for those of us who regularly use Web SDRs, it’s an interesting perspective on how these global receiver networks continue to evolve and expand the reach of radio in the 21st century.

Bob’s Radio Corner: Shortwave Multiplex?

Reported by Bob Colegrove

Incurable DXers are always looking for new challenges.  So it was, I recently did some scanning between 42 and 45 meters (~6600 to 7000 kHz).  Trenton Military on 6754 kHz and the MARS net on 6913 kHz are regulars here, as are a selection of pirates above 6900 kHz.  However, I have never experienced anything like this.  It took me a while to sort things out.  A pirate on 6930 kHz was quickly detected on the upper sideband, but there was some garble slightly lower.  It turned out to be a few folks having a QSO in Spanish on the lower sideband of 6930 kHz.

Two transmissions both squatting on the same frequency.  The irony was, sans carriers, there was absolutely no mutual interference.  Each signal was clearly received by alternately pressing the USB and LSB buttons.  Likely the QSO folks were somewhat out of band for 40 meters, and it goes without saying that the pirate shouldn’t have been there.  Nevertheless, I would call that efficient use of the spectrum.

Bangkok Meteorological Radio: Can you name that tune?

9 Replies

Many thanks to SWLing Post contributor Dan Greenall, who writes:

Bangkok Meteorological Radio in Thailand broadcasts marine weather several times a day on 6765.1 and 8743 kHz USB in both Thai and English. An interval tune is played between the Thai and English segments that has left me trying to put a name to it for nearly a week as I play it over and over in my head. There seems to be a vague resemblance to “Love Me Tender” by the late Elvis Presley but now I’m looking for help. Can anyone “Name That Tune”?

Here is a recording made on October 9 around 1300 hours UTC using the LA6LU KiwiSDR in Thailand. Have Fun!
