[Elecraft] K2/100 with Total Loss of Sensitivity

[Ray G3XLG]

I've noticed the last few days that the K2 seemed to be only working on a few
bands eg 10 metres for the RTTY contet recently was fine but 20 metres
seemed totally "dead". Then on Sunday I found 80metres was fine for some CW
but 40 metres was dead as well.
Today all bands on the K2 just appear to be noise with very few signals. I
tried to tune in the antenna with the KAT100 but couldn't gett any matching
on any band. I suspected the antenna or co-ax cable but when I plugged in my
K1 to the antenna there was no problem with the internal atu and there were
loads of stations on 40, 30, 20 & 18 metres.  So, its definitely the K2
which has a problem.
I'm going to study the troubleshooting section of the manual now but does
anyone have any ideas where i should start?
