[Elecraft] KPA #455 not very well

[DK2GZ at aol.com]

Hello
 
this was exact my problem with #400
 
The problem was the 10pin ribbon cable to the I/O board. It was attached in 
 
the wrong direction on the power supply board and then therefore also   on 
the I/O board, because the plugs are coded. I did reset the ribbon cable  
in  
the right way and all problems now solved. Bandswitching is also  working  
perfectly.
