[Elecraft] K3 Extreme sig mod

[Ken Wagner K3IU]

I believe that the boot up detection is only to determine whether the 
jumper is installed, not whether it has been activated by a strong 
signal. I really don't see a need to report that the jumper is installed 
on the display since one would surely remember if the jumper has been 
installed.

It does work, by the way. I put my K2 on a nearby antenna and keyed it 
with power at about 1 watt while the K3 was listening on a nearby 
frequency with the preamp ON.  With a couple of dits, the preamp turned 
OFF and with a continuous carrier, it turned the attenuator ON. No 
measurements made.

73,
