Contest stations operate on multiple bands from the same property  
without issue. Harmonics should only be heard on the harmonic  
frequency, not splatter across the entire band. You should not have a  
problem with a station over a mile away. What is your antenna and how  
it is fed?

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?
