Re: [IRCA] MONGOLIA. DX test on 1431 AM this week

--- Begin Message --- 
I guess likely former Radio Moscow, US-VoA and US-RFA foreign relay site in use at

MNG Choybalsan 1350kHz 500 kW 8-mast directional sidefire antenna in
150degr azimuth, location 48 00 02.70 N 114 26 17.42 E
see Google Earth image of 03 November 2007 snap.

Distance to Pyongyang KRE 1400 kilometers in 133 degrees. These USSR sidefire antennas are sleweble at +/- 30 degress, I guess, like in Bolshakovo Kaliningrad Oblast.

Former 1350 kHz frequency can be adjust easily to new 1431 kHz channel?

Between 2008 and 2010 it was on mediumwave, too. Choibalsan site, 1350 kHz, 1000 kW transmitter and SV 4+4 antenna (eight mast system, as e.g. 1143/1215/1386 kHz at Bolshakovo), meant for Radio Moscow to China and presumably not put into this use anymore after its completion in 1990.

Gossip has it that some tests had been done for BBC WS but led to nothing. Only Radio Free Asia regularly used the facility, already with Korean, and with Korean only; I assume programming in Chinese was verboten.

I think it's needless to say that Choibalsan is thus the first suspect if really anything appears on 1431 kHz (Kai Ludwig, Germany, dxldyg via DX LISTENING DIGEST)

Choybalsan is conveniently on the far eastern end of Mongolia, not far from the Chinese border (Glenn Hauser, DX LISTENING DIGEST)

Hi All, When Mongolia ran English on 990 kHz back in the early 90s their signal was very strong in Beijing but was not heard in Guangzhou (Canton). This test may also be very directional (Tony VK2IC Magon, NSW, mwdx yg via DXLD)  Viz.:

MNG_MW U-B Khonkhor [981] 990kHz 140 degr 1000 kW Zelenka SGP4+4 / SV4+4 antenna, Location   47Â47'27.77"N  107Â11'04.29"E

Distanz Ulanbataar Khonkhor to Peking 1200 kilometers, 136degrees azimuth. Distance to Guangzhou (Canton) or Hong Kong is rather far 2900 kilometers. wb (Wolfgang BÃschel, ibid.)

 I hope those of you with foreign

 about this DX test for me. I'm not part of those MW and SW
 groups like many of you - or else I wouldn't be posting this

 station is targeting Korea from Mongolia; anyone in
 DXer-heavy Japan would be most helpful, though my contacts
 are rather limited there ---

 I want to spread the info about a MW DX test this week that
 I am helping with (especially those with Asian contacts,
 please re-post). The engineers need any help they can get,
 primarily recordings to see how the station is getting out.
 The guidelines for the test are below:
 
 * Date/Time: May 25-28 1300-1700 UT
 * Frequency: 1431 (power will likely be between 100-500 kW)
 * Location: Mongolia with a target audience of South Korea
 * Send recordings to C0000112@xxxxxxx or
 upload to 
https://www.dropbox.com/request/gXQDEsPBCtGiuXn4UcIb
 * Recording preferences: MP3 format, mono, no less than
 32kbps, and no longer than 30 minutes
 * File name should be the sender's initials (example: mine
 would be "CK" ) - day - time.mp3 (for May 24 at 1am: "ck-24-
 0100.mp3). If uploading to the Dropbox, please send an
 e-mail to the above address stating your listening location
 as well.
 * If possible, do not set the receiver bandwidth to be
 narrow, but wide AM (at least 6 kHz for example).
 
 I hope we can get some help for these engineers who made the
 journey halfway around the world to set up this test (Chris
 Kadlec, South Korea, May 23, WTFDA gg via DXLD)
 
 Very interesting, but a few details are missing, like WHO is
 behind this? Probably religious, Mormon? Or USG? Mongolia is
 already a secret relay site on SW for Radio Free Asia. Is
 this really for North Korea? 1431 looks like a good choice
 in the region, with no hi-power stations on it per WRTH,
 nothing greater than 10 kW in east Asia, 40 kW in
 Kyrgyzstan. And WHERE in Mongolia is it? A big country.
 Here`s another introduxion to it: (Glenn Hauser, DX
 LISTENING DIGEST)
 
 Good afternoon! This is a copy and paste from a Facebook
 group mostly of broadcast engineers. I was one. Tom / Doc.
 
 I hope you guys will grant me an exception for a post void
 of transmitter photos - we're trying to get some help in a
 DX test here in Asia (high enough power that it may be heard
 on the west coast) and frankly, a group of avid radio fans
 and engineers most likely to help fellow engineers test
 their transmitter(s) tends to get the word out best (via Dr
 Tom Gruis, K0HTF, IRCA via DXLD)
