[Elecraft] KIO2 Problems

[ted]

Both of my K2s were connected to the same computer and both suffered the 
same fate of loss of KIO2 communication. I am not sure of the exact 
cause or the exact time it happened..  Several of the USB ports are not 
working now and the computer has been taken off line.

  I replaced a burned out choke and the MAX1406 IC of the KIO2 board and 
all is now well with my low power K2.

I replaced the MAX1406 on the KPA100board, but the KIO2 circuit is still 
not functioning.. All the voltages check out except for the 5V required 
at pin 11 which measures 0V.

I am not sure where to go from here and any thoughts or help would be 
appreciated..

Thanks....ted....aa5ck
