Good Sunday morning all,

 

I have an error on my KPA1500 which occurs when the amplifier is ONLY placed
in "OPER". Given on a minimum of 5.8  to 7.0 watts of drive from the K4D,
the amplifier faults and displays the following: "LOW GAIN RADIO 1". This
occurs on all bands from 160 to 15 meters but not 12 to 6 meters. I suspect
that this will mean a trip back to the mothership. On the K4D, the error
message is "ER31 - POWER INPUT TOO HIGH". According to the K4D manual, this
error code means that it is amplifier induced.

 

I could not find the amplifier error in the KPA-1500 manual.

 

Anyone have any thoughts on this problem?

 

With best regards,

 

Jerry, W1IE
