[Elecraft] Problem with my K3

[Phil and Christina]

I need some advice.  I had the K3 on this afternoon and tuned to the low end
of 20M (about 14.001x).  I had been going into and out of the shack with the
radio in receive mode.  I went into the shack and heard a continuous string
of dots.  I tried to tune the signal, only to realize that it was my
sidetone (the watt meter in the SB200 was bouncing).  I had to turn off the
power supply to stop it.  When I powered it back on, the ERR KEY message was
displayed.  I looked it up and saw that the key line must be active at power
on.  I disconnected the Bencher paddle, and the ERR message went away.  It
appears that the dot contact on the Bencher had changed enough to make it
touch.  I adjusted the paddle, and that problem went away.

The problem now is that on 20M, keying the radio gives a HI SWR message and
the SWR indicates 99.9:1.  This is with either the 20M antenna or a dummy
load.  The other bands appear to be fine.  I fear that I may have fried
something in the 20M output circuit.  Any suggestions?  Help please!
