819 Pyongyang, North Korea?

Such an unusual Oriental accent behind a much bigger than usual Egypt this evening. The time was 2000, which I would have thought a bit late for North Korea. Any ideas?

Thanks.

holy sh.. Egypt with its clock signal is pretty strong up there. did not expect this. it is annoying here in Germany, but Korea would get through every time. I suppose the euphoric voice in the back comes from Mazandaran regional station, Voice of Islamic Republic Iran. I get this every time when turning the antenna a bit away from Egypt towards South East. they have strange music as well as strange style of presentation. North Korea should be playing the NA at this exact moment of time.
Iran has 30 kW and if conditions towards S / SE are good, they can easily be heard in the background of Egypt in Germany.

I have observed the following scheme regarding KCBS during the past days:

1630-17 UTC best possibility to catch it with music
1757 UTC the National Anthem of the DPRK is aired
1800 UTC tx. signing off
1945 - 1950 UTC tx. signing on with test tone
1959 interval signal is aired 3 times
2000 UTC the National Anthem of the DPRK is aired
21 UTC announcement, time signal, news bulletin
(after that, signal is usually swamped out by Shanxi PBS)

this is how it sounds like at 20 UTC , Senderjaeger has made a nice recording recently:

rx. is better one hour later at 21 UTC with announcement, time signal, news:

this is my own recording from this week.

I wonder if Pyongyang 819 kHz might be the strongest tx. all over the world?
None of the other 1,5 MW tx delivers such a signal strength on my portable.
It would easily reach the US and Russia as well as it was heard in France too.

one might not agree to their pol system but I have deepest respect for the technicians who provide this signal.
if anyone told me I would be able to hear this almost every day in winter, I would have told him he was crazy.

Thank you PFM.

I have never known Egypt anywhere near this strong before. It usually sits down in the noise.

Thanks for the timings:
I checked for the North Korean national anthem. Nothing. Even with Egypt on a total fade.
I checked immediately prior to 1800 for the DPRK sign off: Nothing.
I checked 19:45-19:50 for the test tone: Nothing.
The interval signal and national anthem prior to 20:00: Nothing.

As for Iran on 819? It might surprise you, but I never heard this here before, if that's what it is. Another surprise for you ... looking at the all time log, Iran was only logged for the first time on a Beverage on the 2016 Sheigra DXpedition in 2016.

I checked on the half hours for the Iranian time signal, but the same squeaky voice was present and no time pips or any other form of ID.

So we had a rare boost to the Middle East yesterday evening it seems. If I get chance, I will go through the recordings and see if I can dig out anything unusual.

Strange how India is lacking here. I am not fully in the picture for the exotic Far East stuff at the moment.

The strongest is our 2000 kW on 540 :)
I heard with good signal via South African and Sri Lankan SDR.

Yes 819 in NK is a Flagship. The Pre-Tuned radios have these presetes there: (I saw this in an article 10 years earlier)
1. 819
2. 657
3. 2850
4. 3320
5. local relay

6400, 9665, 11680 are for the external audience.

today, NK was audible very well . in fact, even stronger then y'day. worked even downstairs in the kitchen 8-)

best time stamps were around 1535 UTC, 1745 UTC and 1750 - 1754 UTC (only music)
N.A. from the North was heard from 1755 UTC on 819 (and from 1801 on 1134 - South Korean).

NK is now again UTC + 9 or CET + 8 so during our European evening, it is night there and it is non.-stop music mostly aired.

try out in about 50 min when they come back. condx might last.

(KBS 972 and 1134 were fine too--- 3Radio was pretty english today with Queen and Boyzone while KBS Hanminjok played R Kelly and Neil Young)

these tx are really impressive. I wonder what devices they are using. certainly former USSR or Chinese production in the North and former US military in the South?!

Thanks PFM. I deleted the files now as I am short of hard drive space.

Will check later. Conditions are quietening down again ahead of a potential blowout. "The geomagnetic field is expected to be quiet on November 29. Quiet to active conditions are likely on November 30-December 1 when a high speed stream from CH897 becomes the dominant solar wind source."

try at 20.01 UTC exactly. that was the one minute when it was strong during the N.A.
another good moment was 20.06 UTC during the "Anthem of General Marshall Kim Yong Il"
