[Elecraft] XRAY MY K2

The x-ray machines typically don't radiate for a full minute, they just
pulse the xray and the image is captured and remains on the screen while the
attendants peer at it. YMMV

Flash and EPROM contents *can* get altered by x-ray.  But so can Flash in
laptop computers, etc.  I wish I could say the my laptop problems are a
result of xrays, but they are more a result of redmonditis.  :-)

> The system exposed was a fully loaded 100W K2 with the tuner.

I assume this means two boxes - the K2/100 and the KAT100?

Is the K2 giving troubles, or just the KAT100?  Can you run it into a dummy
load without the tuner and see if the problems occur?  Or with the tuner
into a dummy load?

It *could* be that something isn't grounded now that you're back from your
trip and have re-installed your K2 system.  Or some other reason unrelated
to the xrays, but related to the trip or the removal and re-installation of
the K2...

Thinking out loud,
