[Elecraft] Weird issue K3/KPA-500

[W0MU Mike Fatchett]

I am attempting to hook up an Array Solutions DBS-2 Band decoder on the 
K3.  When I have it connected using a Y cable the KPA-500 no longer 
follows the bands it seems to get confused.  I have the KIO rev B board 
which I believe should have the pull up resistors but I am seeing 2.3 to 
2.5 volts on the Band out pins.  I think this should be between 3-5 
volts.  Are there KIO rev B boards that might not have been upgraded?  
SN on this K3 is 2745.
