Hello,
I just spent a most enjoyable afternoon assembling SN 1213 KPA 500. Took my time and double checked every connection, wire, etc. Everything is in the right place and there are no faults, errors etc. when I power it up. However both my radios (a KX3 with ATU in bypass, and a Flex 5000 without an ATU) report high SWR with KEY DOWN. I put my SWR meter on the input side and sure enough, most bands present a 1.9:1 or higher. I have discharged the unit and removed the rear panel just in case the RF input wires were disconnected some how in assembly-both input and output are secure. I am at a loss. Anyone have any ideas? Also, I should mention on receive all bands seem VERY quiet.
Also, my KX3 with ATU enabled works really hard but does make it tune-still no auto band switching and no RF out that I can see.
I was really hoping to work the 10M contest this weekend with my new amp....
