I’m running a K3,KPA500,KAT500 into a 10-80 meter OCFD at ~ 50 ft. It will tune 40M great but fault on all other bands. This is not a new problem, but has been going on for a few years. Any ideas what could be causing this? I’m following the instructions in the tuner manual. Thanks,Jim W7JHR Sent from Yahoo Mail for iPad
