Default "Laser Beam" Sounds on 4.785USB

Strange, pulsating sounds.

That stuff has been operating around that frequency area for several
years. I'm surprised you haven't heard it before. It's an HF Ocean
Radar, which scans for surface currents, waves, and surface wind
directions can be measured through frequency analysis of the
backscattered echo from the oceansurface waves.

There are I believe, several of them operating on the East coast of the
USA, and perhaps in other areas of the world as well.

They make a mess out of 60 meters.

Thanks for that info, I wasn't aware of that.
Just happened to come across it during my dx scanning this evening.

So THAT's what it really is. I had thought it was the new electric meters in
the area. They come in loud and clear on the west coast and it's really
annoying. Do you have any ability to filter them out at all ?
