[Elecraft] IMD and supply voltage

Yep, I remember a certain net control op claiming
to put his rig into "war" mode during a weekly
Sunday net when competing with the incessant
"seeque keyontest" encroachment.

He was running a grid driven 4CX-1000A .  All he
had to do was drive it so a few milliamps of grid
current showed and like magic, the frequency was
clear.

This was the "street-sweeper"  * of radio set-ups
and pretty guaranteed  a QRM free frequency for
the net.

Not sayin' I condone such antics, but it WAS
effective.

 * Street-Sweeper, a rotary magazine 12 shot, 12
Ga semi-automatic shotgun.  Sorta looks like fat
version of the popular Thompson machine gun.





Yes, I understand completely.  From a "Real World
Practical" standpoint, if I have a really clean
transmitter with lovely IMD specifications and I
stuff over compressed, highly processed, all
compressor-limiter knobs to the right audio into
it I will get completely unintelligible audio with
wonderful technical specifications and still
bother my neighbors.

And don't forget. Some contesters *WANT* the
scenario you described above.
No sense in sweeping that under the rug!
