[Elecraft] Weird K1 hangup - no kHz display after memory play/hitting MSG to stop

[Wallace, Andy]

Was operating my K1 last week and saw a weird hang-up condition
with it. 

I had been using memory 1 to send my CQ, and heard a station
coming back to me just as it was finishing the last character
of the message. 

Once I did so, I did not see the END displayed on the '
front panel. In fact, it went blank! No kHz display at
all. I hit Band and saw 14...but then no kHz again. I 
changed bands, and saw 21, 7, etc -- but never the kHz
and I don't think I heard any relays clicking either. 

I wound up cycling power and everything was fine after
that. I have not been able to duplicate this, either.
Probably some ultra-critical timing involved, but I 
am passing this on in case Gary can find something in
the firmware code. I doubt most users would ever 
encounter this!
