Need Help w/KAT1

Lou Roux-3
Hi all,

I just completed a KAT1 for an older K1. The tuner passes all tests but
won't tune an antenna or a dummy load. When tuning all the relays
activate but at the end I get the message r 9.9. The MCU is v1.09e. I've
very carefully gone over all solder connections looking for bridges etc.
and component placement, everything is in order.

I'm totally frustrated and in need of help! Please contact me offline
at   w6ur at arrl dot net.

Thanks for reading,

Lou - W6UR

Lou,

What happens when you put a dummy load on it and attempt to do a TUNE -
what SWR does it report?
If it is still 9.9 or something else above 1.5, then you have a problem
with the K1 tuner - any chance you wound T1 in the direction opposite to
that shown in the manual?

If the dummy load tunes OK, look for an open or a short in your antenna
system.
