I've had a fairly continuous noise that I've been hearing for several months now. It's broadbanded enough to be hear as low as 80m and as high as 20m. The signal strength can vary day by day and also by frequency, generally higher strength with higher frequency. It's continuous. I've not had a situation where I've been listening and its disappeared.
There are some power poles near me that have forever been on the repair schedule due to a noise complaint I provided to the power company a long while back. However, that noise source is very different sounding than this one. It’s much more of a classic 60 Hz buzz whereas this one is much more, err "bassy" sounding.
I've not been able to hear it in my car and I've not yet been out hunting with my R30CC in portable mode. I guess I keep hoping the power company will repair the poles and I kill two birds with one stone. It’s there when the radio is run on batteries, so I’m confident it’s coming in on the external antenna.
I've recorded it and I wonder if any others have heard this and identified it? Joe Farley was nice enough to take a look at it on a scope and he commented that it definitely has 60 Hz content in it.
Any thoughts would be appreciated.
