Yes, please give us more information, including your call.

It does, however, sound like its just RF overload, which would not be your fault. It can usually be fixed with ferrite cores on the long wires, like speaker leads. I've had to do this in my own house, as well as those of some of the neighbors. It's no big deal, unless the neighbor is hostile. Try to avoid that.

An example: A few years ago a neighbor had one of those digital to analog TV converter boxes, hooked to rabbit ears. He was right between Europe and my antenna, and I could wipe it out with 10 W. Ferrite cores on all the cables coming into that box completely solved the problem up to 1500 W, and the neighbor was completely satisfied. He even gave me my cores back when he got rid of that box.

Please collect some more information, and get back to us.

Wait! Unless I missed something, we don't even know whether this is a matter 
of RF susceptibility at the neighbor's end, or something spurious from the 
transmitter. Is the interference to a device which is not supposed to receive radio 
signals at all, like an audio system? Is the device receiving the interference one 
that the neighbor just got? There's just no point going any further until that's 
sorted out.

My previous suggestions accidently went only to John and did not go to the 
list.  Here is what I sent a few minutes ago:  This is a repeat with one additional 
idea tacked on at the end.

Check your connectors and grounds that are inside the shack.

Make sure you didn't accidently over-drive the amp.

Check your main ground connection to earth.

If nothing bad is found then start looking at the feedline and outside 
connectors on your 80M antenna.  Depending on where the antenna is located, 
make sure it hasn't somehow started bouncing up against a metal object like a 
gutter.

Others on the list will probably come up with additional ideas.

One other idea I have is to bypass your amp and see what happens with lower 
power.  Alternatively, you could leave the amp in line and reduce the amp's 
power output to see if the interference stops at some lower power level.

I was going on the language he used re "the neighborhood", which to me
implied more than one neighbor complained.  However, maybe it was just one
neighbor, as others have apparently assumed.  We will have to get more info.

What was the nature of the complaints?

If you haven't changed anything inside the shack then maybe something is
loose or corroded outside.

Nothing in my shack has changed the last 3 years but this weekend the
neighborhood complained about 80 meters. Any suggestions what to look for?
