After I wrote my previous message about interference on 7.415, I turned to
5.105
and found some sort of buzzing interference on that frequency as well. At
0200
UTC it was happening every few minutes for a few seconds, and over the course
of
an hour it became more frequent and toward 0300 the duration began to
increase
as well. Is someone trying to jam them, or is it just coincidence that
there's
some type of signal on both frequencies? The signal on 7.415 is very
high-pitched and sounds like it could be some sort of data signal. The
signal
on 5.105 just sounds like noise, unless it's some sort of broadband radar.


5.105 moved their signal once because of some Morse Code data type
transmissions;
- maybe That signal moved too!

7415 is ( for me in NYC) getting interference from Radio Botswana..
and suffers from crummy propagation after 01:00
