I live in Waco Texas and there are no known windmils or inverters nearby that I
know of. I have a lowband noise that is pretty broadband starting around 1mhz
on the am broadcast band and running almost non stop until around 2.5mhz or so.
It is a buzzing noise on am and a hetrodyne on ssb or cw. Once in a while I
hear what sounds like ascii for a couple of seconds and returning to a solid
carrier modulated with a rough ac note around 200hz. I took my E1 receiver on
battery power around the house and could not pinpoint the problem so I turned
the main breaker off killing the whole whuse but the buzzing was still there.
So I took the portable receiver in my truck and drove around the neighborhood
and the noise is still there everywhere I go. Bear in mind I cannot hear much
on 160 or the am band because the signal strength is at least S9 or more. The
noise did not go away driving around the block so I drove further to the edge
of town to a rural area and the noise is sti
ll there. I did this a couple of nights ago and have not tried this in the
daytime. The weather has turned icy and cold so I will not try anymore until
this next weekend when the temp goes bsack to the 70s. I keep trying to find a
good topband antenna but with this noise I will never hear much. The noise is
down a lot by 80 meters and not heard any further up the band.
Anyone else hear this? WB5OXQ
