[Elecraft] KAT100 problem

[John Wiener]

About a week ago I was transmitting SSB on 20M when the K2 shut  
itself down unexpectedly.
I turned it back on and found no error message and all seemed well.

I now realize that I hear no relay clicks on the KAT100 when changing  
bands.  On 20M I now get a 2:1 SWR, whereas before, I think after  
relays the SWR was lower.
On 30M, a test carrier displayed alternating 1:1 and 5:1.
Also, before this incident, tapping the "Tune" button caused a self- 
terminated 20W carrier.  Now the Tune button puts out full carrier  
and is not self-terminating.

Any ideas?
