DR Kalundborg 243 kHz Information and Program Schedule.
The carrier is switched on some minutes before the start of the interval signal (IS) and stays on for some time after the end of each broadcast.
For a fine reception, you should use the very sensitive Danish SDR (Softwave Defined Radio) located near Skanderborg in Eastern Jutland: www.
Also, there is generally very good reception using the University Enschede Twente SDR receiver, and north German SDRs.

About the programs:
The interval signal (IS) at the start of the broadcasts is a recording of the mechanically played IS and is an old Danish song, “I dreamt a dream tonight about silk and rich clothes…“. It was used for the first time on August 28, 1931.
The other interval signal heard is composed for the long wave broadcasts.
Weather forecasts: They were broadcast directly from the Danish Meteorological Office. The forecasts terminated at 11.45 CET on november 1st, 2023 and were replaced by a short info program and
interval signal.
The News relays are taken from DR’s P4.
The Church Service is broadcast live from the Cathedral of Copenhagen, but remotely controlled. Also broadcast on DR P2 and DR TV channel 2.
The Excercises, “ Body and Movement“, are a number of old recordings, each lasting 10 minutes.
Marine Intelligence, broadcast from the Defence Operations Center, including gunnery practices at the end. The information is repeated.
The very last broadcast is on December 31, at 17.40-approx. 18.30 CET. Information in Danish about the closure of 243 kHz: (use Google translate).

Hong Kong

“Voice of the Great Bay Area” (CNR-7), to Hong Kong/Macau and surrounding areas, is the famous service of China National Radio(CNR). There is another CNR’s service exclusively to Hong Kong – CNR-14 “Voice of Hong Kong”, which is not mentioned in WRTH2023.

Their recent schedule and frequencies; 24H except Monday 1605-2005UT
FM 87.8MHz Mt.Wutong transmitter site, Shenzhen, Guangdong Province
AM 675kHz RTHK Peng Chau transmitter site, Peng Chau Island, Hong Kong 10kW

The service was started in 2011, when RTHK(Radio TV Hong Kong) set up digital radio channels. CNR joined  as “CNR-14 Voice of Hong Kong”, and had been broadcast on Channel 32 of RTHK digital radio between 2012-2017. On September 4, 2017, when RTHK terminated the digital radio service, “Voice of Hong Kong” moved to 675kHz (RTHK AM radio channel 6), replacing BBC World Service 24H relay. On November 1, 2017, FM transmission from Shenzhen was added for better coverage. After “Voice of the Great Bay Area” was set up in September 2019, the role of ”Voice of Hong Kong” seemed to be absorbed by this new service. At present there are only 4 own programs, other programs are all from “Voice of the Greater Bay Area” (simultaneous or re-broadcast).

Streaming on RTHK site 
Checking on 675kHz by Kiwi SDR, located at Waterfall Bay in Hong Kong Island, only 10km far from the transmitter in Peng Chau Island, the signal strength was not strong with some noises. The reception was worse than on RTHK 567 and 621kHz from Golden Hill transmitter site. It is said that Peng Chau transmitter site is being rebuilt and is using temporal transmitting antenna at least until the end of 2023.

Alaskan beacons missing or gone?

I’ve noticed that the Alaskan Beacons on 529 and 530 appear to be gone.  I don’t think it’s just conditions, either.  I can hear 525 ICW Nenana (near Fairbanks) all evening, but nothing out of 529 SQM, which is usually very powerful here all day long, 529 FDV Nome, and 530 ADK, Adak which normally is also heard quite well.  So, possibly permanently off?  Compared to just 2 or 3 years ago, the LW NDB band is really emptying fast!

VTR 350 will eventually go away.  It was off awhile back and they were having trouble getting parts for it. There will come a time soon where it get broken and not be repaired.

Arabic Service website & on-air observations.

There’s a website dedicated to VIRI/IRIB Arabic Service at (registered in Canada) featuring a SW/MW/FM and satellite frequency schedule which appears to be accurate as far as I can tell, albeit greatly at variance with other published sources. It shows the service on 576 & 1224kHz round the clock and on four SW frequencies in various time blocks in the 0600-1730UT period, usually one tx at a time (just two txs overlapping at 0930-1030UT). All but one of the five SW transmission blocks are aimed at Yemen. My monitoring observations via webSDRs in the Gulf confirm all four SW frequencies are
indeed on air within the time periods stated, though often with extremely low modulation on a strong carrier.

David Kernick, Interval Signals Online to WOR iog (2023-11-25)

In case anyone else wants also to take a look at the frequencies:

576 kHz around the clock would mean that the Mahshahr transmitter now always uses the daytime frequency and has abandoned its former nighttime frequency 1080 kHz. Would be no surprise at all, one of the two mediumwave antenna systems of the station is gone, like the shortwave antennas (with the exception of a single tower). Can’t confirm neither frequency with the TWR Cyprus SDR right now, only 1224 kHz. On 576 kHz nothing else than Bulgaria and on 1080 kHz some other signal as well.

For the shortwave side the question remains if the night / early morning frequencies 7220 and 9725 kHz are not in use. Otherwise this schedule confirms the observations that there is neither a separate Voice of Palestine shortwave transmission nor are the Zahedan transmitters in use anymore.

That very low audio – a couple of years ago the editorial offices complained and some repairs had been made. But those who complained have since been stripped of their shortwave airtime and no one seems to care anymore. I would not be surprised if the remaining three transmitter operation at Sirjan (or perhaps now even further down to two ones? – hard to tell because a number of the HFCC registrations have China co-channel) will cease rather sooner than later.

Former ILR MW closures.

The dates currently planned for the switch-off of the remaining AM transmitters in the North of England, Scotland and Northern Ireland are 11-13 December. Switch-off normally occurs at midnight. I’m afraid I don’t have specific dates at the moment as Arqiva are still planning the switch-off order, depending on when their engineer can visit the sites.

Reception of Droitwich 198 kHz this evening is weaker than normal. I have seen unconfirmed report this is currently running at 250kW instead usual 500kW. Poor reception in Merseyside at least. Normally I get thus no problem.

James Robinson (2023-11-23)

Here at my QTH in southern Denmark BBC 198 kHz is heard very well tonight.
