Hi,
I have a quick question regarding operation of my KAT500 tuner. I have
a K3 feeding a KPA500, feeding the KAT500, feeding a 6BTV vertical which
is tuned up well, and can run with the tuner in bypass, and keep SWR
below 1.7:1 on all bands...
If I am using the KAT500 as a tuner, and I watch the SWR indicator on
the KAT500, for an instant, at key-down, I see greater than 3:1 SWR,
then it drops to normal, all in within a few milliseconds, to
microseconds. Every so often this will fault the amp.
If I put the tuner in bypass everything is normal... No issues, the SWR
indicator operates as normal, the amp never faults...
Anyone have a guess as to what is happening?
