This thing will certainly work, and it will certainly produce enough
radiated harmonic and intermod power to be a source of noticeable
interference. Just remembered that when I was going to the University
of Illinois back in '44-'45 there was strong local BC interference due
to intermod between the signals from the two local BC stations.
Allegedly it was fixed later by eliminating the source, which was rusty
junctions on a tower someplace. Hear lots of that stuff around here,
but suspect that a lot of it is generated in my own gear.
