Topband: topband noise update
Here is an update on the noise. I now believe is is close to a 60 cycle note when using the am mode. Also using the E1 on its whip antenna and using the d cell internal power I tracked the noise all the way down to the bottom of the lw band to 118khz which is as far down as this receiver wil go. On the broadcast band only very strong am stations can quiet the receiver. I also tried a small portable am fm sw radio with a loopstick for am and the noise is there and rotating the radio never changes the signal strength so it is everywhere. I never noticed this noise a few months ago when I would dx on the broadcast band. Should I bother the FCC with this? Or call the power company to see if they have an idea? Could this be video noise from bad cable leakage? It is just everywhere. This is not just a ham problem but makes broadcast band listening very poor also. At 2.5mhz WWV covers the buzz at night with a very strong signal and by 3mhz most of the noise is down to around s5 or lower. Who knows what other services could be bothered. Could this be noise from the smart electric meters? I am not sure how they communicate but I would expect the frequency to be much higher. I know every few blocks there is a box on the utility poles with a upside down antenna which looks like a center loaded 800mhz type. I am really upset that I cannot enjoy radio anymore when I am home at night.. WB5OXQ. _ Topband Reflector Archives - http://www.contesting.com/_topband
Topband: Low band noise
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?

Topband: I meant a full wave loop instead of a 4 square.
I meant a full wave loop If I can support a wire antenna at 50' or maybe more in tall pine trees and have 1.9 acres of space to use which would work best. Lots of tall pine trees on the lot. I assume the trees in the center of the square will really not be an interfearing factor. If I feed with window line will it work well for a multiband antenna? I assume the inverted l will need long radials to work well and that is possable, does the square antenna also need radials and if so how oriented?
