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???
No, it's not the Urumqi transmitter John. When conditions allow me to
hear that one it's alone, and has a clean signal. At other times I see
(and hear) the same mess you describe.
Thanks for the congrats on Oct 21 logs. Yes, quite an unusual
morning. I'd only heard 1521 and 1107 from Urumqi once before this
season, but this month I've heard 1107 three times, and 1521 more than
that. Certainly this has been an October to remember.
