Last night, I heard a very bad noise on the band. It sounded like a bad
connection somewhere that was mixing AM broadcast signals. It was all
over the band, but seemed worse around 1790 kHz. It wasn't steady, but
breaking up - almost sounding like someone sending garbage CW.
This was similar to a noise I had heard a couple of years ago, but it
went away after one night - before I could track it down. I wanted to do
enough DFing last night to find out if it was something local on my
property - or far away.
I got a bearing on it from my house (sort of west) which matched the
beverage that heard the signal the best. I found I could hear it on
my car AM radio tuned to 1710 - so I started driving west. The signal
stayed pretty constant in strength even going a mile or more - so it
was't something local to my QTH.
I do have a big AM station about 3 miles west of me (KXL - 20 KW at night)
and I drove over there and determined it was not that station. From that
QTH - I got a good bearing on the signal and it appeared to be from another
big station that is about 10 miles from my QTH (KEX - 50 KW).
I figure if it is coming from that far away - then it isn't something that
is totally parasitic. It is probably also loud enough that other people
can hear it.
Of course - this morning as I was driving by there on my way to work, it
was all quiet. Hopefully, it will stay that way.
