[Elecraft] Help-damaged front end?

[john]

I've got a K2 / 100 that has had a dramatic loss of sensitivity.  This 
occurred after a thunderstorm, when the antennas were disconnected outside 
the house, but there was still some residual coax feeds (unterminated) 
still connected to the K2.

Where to start to look? Appears to have lost sensitivity on all bands, all 
modes. Transmit is still fine (at least CW) .

Thanks
John
