I understand and agree with your comments, Peter. This reminds me of a
recent contest where a ham was complaining about a station that was 30KC
wide on his rig. Several other stations quickly responded that he should
get a better rig.
The offending stations I am talking about are the ones located at least a
hundred miles away. I can easily detect them with my Yaesu 9000.

A signal usually is not getting wider by amplification, neither by amplifier
nor by antenna gain You probably can not move closer then 5KHz closer to you
neighbours frequency while he is running 5W 100m away from you.
But don´t tell him he is running excessive power or consuming too much band
with ,-)).
The inter modulation on typical transceivers usually is not better then
-30db down and sideband filters have no shape factor of 1.
How behaves the receiver with big signals, especially those with all
selectivity in the dsp only and no bandpass filters for the ham bands?

IMO the real problem with excessive power is during contests where a really
big signal covers about 5KC. No antenna or rig can be selective enough to
deal with a signal like that while trying to operate on a nearby frequency.
