[Elecraft] P3 bug

[Richard S. Leary]

Vic, Joe,
I can't replicate it here either. Tried it on 17M, both with K3 in test, and
100W to dummy load. Using K3, P3 (no SVGA), KPA500, SteppIR DB-18,
microKEYER II, and WriteLog 11.23L. No glitches seen.
73,
Rick, W7LKG

I have run your test and Vic's test literally hundreds of times with
absolutely no "hang."
