Just completed my KAT1 for my K1 that I finished last night. All the tests
seem to work properly, and I get a r1.0 (SWR of 1.0) on all 4 bands (7, 10,
14, 21 MHz) when transmitting into a dummy load. However, when
transmitting into my attic dipole the KAT1 can only achieve a match on 14
and 21
One other thing. When, for example, I tune on 14 MHz, then tune on 21 MHz,
then return to the same frequency on 14 MHz, the tuner doesn't seem to
remember the 14 MHz setting. The relays clatter a while as the algorithm
re-finds the best SWR. Is that right???
