Re: [IRCA] 1107 from Asia

John,
 
The 1107 kHz ragged-carrier mystery was noticed here last year also,  and 
the threshold-level TP audio was almost always weak music,  never with ID 
clues. Even after a Grayland trip last November, the 1107  mystery was 
unresolved.
 
After setting up the 9' loop this month I made a serious effort to  
investigate who this weak 1107 music station was, and thanks to a tip from  Chuck, 
I was able to check the KBS parallel during a music peak, to confirm the  
HLAV identity. Shortly thereafter, I could detect Korean-language speech on 
the  frequency. According to Chuck, the station is never very strong, even at  
Grayland.
 
Oddly, whenever HLAV has fair audio on 1107, the carrier sounds relatively  
clean. It seems that the ragged tone is coming from some other source,  
although I've never heard any co-channel TP with HLAV here (like the  Japanese 
commercial stations you have heard).
 
73, Gary

Gary  DeBock and I have both been watching this frequency lately, in 
fact I've  been watching it all season. Using my detailed spectrum 
display on the  313e (4 kHz = about 4" in a oscilloscope-type display) 
I can see that  usually there is an on-frequency carrier there that is 
ragged and muddy...  and the graphic spike, clean, crisp and nearly 
vertical with a good  transmitter is all rough and it is more spread 
out at the base than  normal. There is usually at least one well-tuned 
transmitter there, too.  Often, that is HLAV from South Korea, but it 
has been one of the two or  three smaller JJ commercial stations, too.

Usually the two (or three?)  signals combine to just produce garbage 
audio.  However sometimes,  usually near band-fade, the nasty 
transmitter will fade out first, or the  clean signal will 
dominate.  This same situation was going on all  last Fall season, 
too.  Does anyone have any idea who the nasty  transmitter 
is???  Surely not Urumqi???
