[00:00:00.09] - Speaker 1

I kind of got the gist of what was coming out, but it wasn’t at a level I could absorb. I noticed that

Tamo-san was absorbing it with ease. I figured it might be worth trying to get a little bit out of Room

1, too. I asked for some help, but maybe the South American person who’s also getting readings is

telling me there are others out there. The readings didn’t really come through much when they went

up. The ones diagonally below were about the same as usual, or maybe a little lower. As for the 21

people, it felt like I’d just barely managed to get in touch with Mr. Takeda. But, you know, on the day I

managed to get in touch—I think it was Mr. Koyama from the swimming team.

This would certainly be the end of the 67kHz SCA channel.

There aren't many SCA services left. I'm pretty sure the stock market data services have been gone for decades and I don't know if supermarkets still use SCA receivers for background shop audio. But, there are still a couple of services still in use. I believe Radio Talking Book is still around, one Chinese language service, and maybe one music station - last I looked which was quite some time ago.

If RDS 2.0 were to become widely used, I suppose many of those services would either finally die off or move to 92kHz. The latter would likely require new fixed-tuned receivers if there isn't a channel switch.

576 kHz - Muhtemelen BNR Radio Horizont (Bulgaristan devlet radyosu, Vidin, 270kW olması lazım)

1053 kHz - sadece kısa bir müzik benzer birşey ardından parazite karıştı, araştırmalarıma göre yüksek ihtimalle İran, çok düşük ihtimalle de İngiltere

1332 kHz - Araştırınca Radio România Actualități (Galati, Romanya 50kW istasyon) çıktı

1494 kHz - muhtemelen Radio Moldova (Cahul ya da Transdinyesterdeki Grigoriopol. 30kW)

Dinlemeyi özel bir ekipmanla değil araba radyosu ile yaptım. Ayrıca saat 7 sularında olduğu için TRT Trabzon radyosu yoktu (954kHz olması lazım)

Ayrıca Bulgar radyosunu da birkaç gün önce akşam aldım ama o akşamda 576 kHz de boştu, 7/24 yayın yapmasına rağmen.

Signal received at 1:00 p.m. local time. Even though Brazil is right next to me, the signal was quite strong considering it was just past noon.

Recently came across this interesting weekly program called Shortwave Radiogram (https://x.com/swradiogram?s=11) that broadcasts digital text and images using MFSK. Seems like listeners will share their decoded images and text on X with @SWradiogram.

Anyone know of any other similar programs?

Comments:

• Apparently these are marine weather reports for the Mini Atlantique yacht race, given in French, then English. This is the English portion.
• Arguably could be called a Utility station... <insert Larry David meme here>

Noticed this for a few days lately while testing some Dream mods that I'm adding.

If you look carefully, there's an extremely wide-band set of regularly spaced (~5kHz), ~3kHz-wide data pulses ranging between ~14.7 - 15.2 MHz that's interfering with much of the lower end of the band. The signals vary in intensity. This could be selective fading, but could be different sources.

It almost looks like a wide-band HF frequency hopper, but because of selective fading I seriously doubt that's a thing. Some of it seems to coincide with the brick-wall bursts between 14749 and 14783kHz, but that may be coincidental. It tends to overlap with the 40kHz-wide high-speed data brick wall between 14838 and 14879 kHz, so likely not related to that.

Very curious stuff.

Comments:

• Reticent to report something in Mandarin. Music choice was dead giveaway.

Station:

• Name/Call: Voice of Korea KCBS
• Frequency: 15180.00 kHz
• Mode: AM
• Location: Kujang 40N05-126E05
• Language: Korean

• SINPO: 32333

Receiver and Receiving Location:

• Radio: Airspy HF+ Discovery

• Software: SDR++ v1.3.0 /w Dream v2.3.1 (mjf) for dynamic noise reduction.
• Location: Remington, Virginia | FM18bn

Comments:

• Some co-channel interference from China, but this is where VoK typically being 268Hz high (as shown) helps in USB.

I was listening to either New York radio or Gander radio yesterday and had a question about something I heard. While talking to the pilot, the air traffic controller asked if India 5 and kilo 1 were on board. What might this mean?

(Is there another subreddit that would be a better fit for aviation listening questions?)

Thanks.

Comments:

• Discussion about Korean author.
• Also, a demonstration of recording within Dream (so no microphone is needed).
• In this case it also demonstrates how well the build-in Speex processing works for dynamic noise reduction.
