Hellllppppp Just recently I started to hear an S9 noise level at it's highest range in the 14 mhz area. It tapers off in both directions. So - I can no longer operate on 20 meters (CW)/.

I use an 817 QRP and a stealth long wire as I live in a condo.

I traced this new noise to my AC lines, and assume it comes from Con Edison..

What can I do about this??

Thanks, Peter K2MMT

This doesn't sound like Con-Ed to me.

I'd start looking with an AM radio or ham rig with a coax loop antenna and start looking for the real problem. It could be anything from a touch controlled lamp to a bad door bell transformer. If you are sure it is Con-Ed, call them. I'm sure they are very aware of the FCC's recent clamp down on electrical induced noise.

let's get it straight... qrN - natural
qrM -  man-made,
AC lines were man made last time I checked... or did they start growing somewhere in the jungle???

A noise canceller might help if it is truly QRM and coming from a SINGLE SOURCE. Check out the AES catalouge for the "Timewave ANC-4".
