[Elecraft] K2/100 in a high RF environment

[Chuck Chandler]

Some background here -

I volunteer aboard the museum ship USS Slater in Albany.  She is a
destroyer escort restored to her 1945 configuration as she was sent from
the Atlantic to the Pacific after VE day.

I try to put it on the air every time I'm there, once a week or so,
maintenance issues allowing.  We use a K2/100 and KAT100 patched through a
WW2 vintage Transmitter Transfer Panel to a choice of the ships original
wire antennas.  These were mostly verticals used for receiving back in the
day.  We can also use the two original transmitting antennas, long wires
running fore and aft.

We are restoring a TBL 400 watt transmitter, which is only connected to the
fore and aft long wires.  The output exits the top of the TBL cabinet and
consists of copper tubing that runs along the ceiling (I know, overhead...
I'm a civilian) to where it exits Radio Central.

Legend has it (and I have no reason to doubt it, I've seen the repair
invoice) that the last time the TBL was fired up the KAT100 was damaged.
Our practice is to unplug the feedlines to the KAT100 at the Antenna
Transfer Panel, as well as where they connect to the rear of the KAT100
itself.

The repair invoice says “The wattmeter in this KAT100 had been damaged. D1
and D2 were replaced. R1 was found to be open and replaced. C31 was not
well soldered. “

Im wondering if unplugging both antenna feed lines from the KAT100 is
enough protection from a 400 watt transmitter firing up a few feet away?
