Buy an attenuator, and a tinySA, or get an SDRPlay, and run the Spectrum
Analyzer software. Take a few SA shots, that will tell you if it is
him, or you.

I have one of those legal-limit hams about 2.5 km from my house. Seems a
nice enough guy, except that he uses 1.5kw for EVERYTHING. When he gets on
40m, I hear him on 2 other bands via harmonics. He splatters all over 40 so
there's no reason for me to even have my rig turned on when he starts
transmitting. I can't tell if it's a bad radio on his end or just front end
overload on my end. It's frustrating to try to do a bit of CW and find that
I can hear him almost as well on 15m as on 40 and 20. I haven't checked
10m, but my guess is I'll hear him there, too.
I talked to him about it, and he basically blamed it on my radio's
insufficient rejection. It's a KX3. Is he right, or should he check his
radio for unstable harmonics?

Exactly right, Vic. A dirty rig, whether generating clicks or phase
noise, is putting his trash on YOUR frequency. You are screwed by his
choice of a lousy radio. And he doesn't care. I've got a neighbor like
that.

I live in a place where there is a ham with a legal limit rig and a big
beam less than 1 km. away. Antennas are line of sight. His signal
renders about 10-20 kHz of the (CW) band unusable, with lesser effects
extending out farther. He does not have clicks; it is phase noise (or
something like that).
I have experimented with attenuators and they have NO effect on the
apparent width of his signal. Therefore I conclude that the problem is
not in my receiver (K3, not S, upgraded synthesizers).
I don't know what kind of transceiver he is using, but I think more
attention needs to be paid to transmitter cleanliness, rather than to
continue the race for dynamic range.
