[Elecraft] T32MI K3 rig problem

[Rich - K1HTV]

Maury,
   Regarding the 40M problem with Derek's K3, it may be related to stray 40M RF
getting into the radio when it is keyed. If this is the cause, an easy fix may
be to create an imaginary ground on it by connecting a 1/4 wave long (around
10.56 Meters or 34.6  feet) wire to the ground screw on the back of the K3. The
high impedance end of the 1/4 wave wire is transformed to a low impedance at the
radio. This should reduce any stray RF around the radio. It is a simple thing to
try and may fix the problem. 

I would be interested to hear if it fixes the 40 Meter problem.

I had no difficulty in working T32MI on CW & SSB with 100 Watts and a wire
antenna from my QTH in Virginia,  my IOTA number 964. They are a great
operators!

This morning local time (Saturday 21:00 gmt) we started our journey to Caroline
island. Estimate 5 days sailing. Almost 9,000 Qs in our logs from the 3 days on
Malvern. Derek's beloved Elecraft K3 has a problem! On 40m only, the instant the
rig is keyed, even at min power, it switches off as if the supply plug is
disconnected. After an indeterminate delay power is restored and the rig can be
used on other bands. Any ideas, please contact Maury, IZ1CRR (iz1crr @ tin.it).
