[Elecraft] K2 Software Problem?

[Geoffrey Mackenzie-Kennedy]

Geoff,

Have you tried pulling and then reseating the MCU on the Control Board?  My 
k2/100 #3255 "froze" on two occasions some years ago due to "corrosion" 
between one or more of this IC's pins and its socket.  I replaced this 
socket with a "Turned Pin" type after the second episode, a type of socket 
which I should have used when building my K2/100.

73,
