What a great surprise this morning! After several days of mostly
poor propagation in the morning, I found JA7NI peaking an honest 599
this morning. After working Kuni I decided to try a CQ. Finding no
clear frequencies in the upper part of the JA band without crowding
someone, I opted for 1811 where my noise level was elevated 10 dB by
some local (?) source I have never been able to track down.
Despite noise and deep QSB, I was able to work 16 additional JA
stations, many of them for the first time. While this is commonplace
for many east coast stations, it sure was a big thrill for me! This
was my first ever JA "run". Several other callers were lost to QSB
and noise. I'm sorry I couldn't copy everyone who called me.
I hope someday I may figure out what this noise is. It affects 1810
to 1816, peaking around 1814 where it is usually +40 dB from my
ambient noise floor. It is present 24 hours a day, but stronger in
the daytime and evening hours, weakest in the early morning. It is
half way between a hiss and a growl. Trying to track its source has
been fruitless since the strength varies little as I drive around.
From home, the strength of this noise varies only a little as I
switch among my 8 Beverage directions. Strange...
73,
