Call for wideband AM recordings during the closure of BBC4 on LW

Dear friends of AM radio,

As reported in several postings (e.g.https://mediumwave.info/2026/06/24/united-kingdom-590/) the legendary Droitwich LW transmitter on 198 kHz will go silent on June 27 in the early morning.

The COHIRADIA team (www.cohiradia.org) will make broadband IQ recordings during he last hours of the LW band to preserve the LW signal for playback in the future. However, there is no member directly located in UK, so the signal quality will depend on atmospheric conditions. We would therefore be glad if a volunteer who possess an adequate high-quality SDRs and who is located in or close to UK could help us capture broadband AM recordings in or near the UK. If you’re able to assist—or know someone who can — please reach out to me hermann.scharfetter@gmail.com

To avoid confusion: We require full wideband recordings in IQ file format, say 130 – 300 kHz LW at least or, even better, say 100 – 1800 kHz for capturing both, LW and MW at the same time. We do not look for audio recordings of individual stations. Ideally, these recordings should be made at a site with low QRM using a high-quality SDR with at least 12-bit resolution.

Closure will be at 1am BST, but we would appreciate a recording over several hours, starting maybe tomorrow, on 26th of June around 19:00 UTC.

Best regards, Hermann Scharfetter  (2026-06-25)

756 (RNZ),
882 (Plmnt /Sanct) ,
990 (Apna),
1332 (Gold) ,
1476 (Sport Nation) are all still on.

Funkisradion in Halmstad plans to broadcast on both FM and medium wave this weekend during DX-Parlamente in Ullared. Henrik Pålsson is coming to Ullared to give a talk about his station, but the station also plans to broadcast on FM 100.6 and medium wave 1602 kHz. The station has a temporary licence to broadcast on medium wave. There are also some plans for the future of shortwave, given the changes in legislation. https://funkisradion.se/

CBC has closed CBKG 920 Granisle BC thus completing their move to FM 105.9. The new [more correct] calls are CBYG-FM-4.

October 16, Radio Center No. 5 (Kaliningradskaya oblast) – will turn on a medium-wave transmitter to conduct a daily test.
16 October – 17 October 16.00 UTC
549 kHz / 600 kW.

Full operation of the RV-372 transmitter was stopped on November 30, 2014, that is, 9 years ago! Then, he worked at a frequency of 1215 kHz. A year ago, the team of the transmission facility returned to their home workshop to revive the lamp giants. For the test, the frequency of 549 kHz (also Kaliningrad) was chosen, which is due to the peculiarity of the antenna used.
Yes. This transmitter can produce many times more power. But at this stage, the task of “accelerating” kilowatts to the fullest is not worth it.
The purpose of the test activities: checking the transmitter in continuous operation. Study of coverage areas.
This time, the test will begin in the evening. This was done on purpose so that the most impatient people could try to receive the broadcast without waiting for it to get dark.
We urge you to try the test on ordinary household receivers (including those from China). If this does not work, be sure to indicate that the reception was carried out using more advanced amateur equipment with an external antenna. Standard car radios are also welcome. That is, everything that is close to normal conditions. But this does not mean that reports from radio amateurs with serious equipment are not interesting. Everything is taken into account – especially distant points.

I look forward to your feedback in VK, Telegram, and email.
I kindly ask you not to delay with messages about your appointment – on October 19 I’m flying to Kaliningrad with a report. I will convey your information and greetings (if any) personally.
What is needed in the acceptance message:
1. The place where the reception took place. (To the extent of an apartment, this is not necessary. A locality or region is enough)
2. Receiver
3. Your rating
4. Video/audio – optional and possible.
5. If you want to add something from yourself.
Your messages are a tribute to the people who have restored the now unique equipment and are not going to stop there.
Cards are not required for the test. It may be possible to send several letters for the most detailed reports.
I’ll be in touch in TG, here in VK. For those who prefer, write to [andrey_hamradio[at]mail.ru].
I will try to answer promptly.
Inform everyone interested!
I wish you success!

From “RUS-DX” # 1259, Sunday / 15 October 2023 via Anatoly Klepov (2023-10-14)

1050 CJNB is announcing it is now back up and running again, after being down for the past week or so due to transmitter issues.
The station was plagued with technical challenges after lightning storms caused the radio transmitter to fail.
Program Director Nic Fransoo said the lightning storm went through the area and resulted in an immense power surge that struck the station’s main transmitter in early June.
