In your note on the 6M problem you didn't indicate if you tried the K3 in the

tried to find a match on my 6M yagi with a known relatively good 1.2:1 SWR. In
the BYPASS mode the SWR looked fine. Using the ATU

Yes, my problem is that I have terrible SWR when the ATU is in BYPASS and
the antenna is a known resonant load. I also tried to tune into a DL and DID

SWR was around 8:1.

The KPA500 has plug in power supply. Is there a different standard for a power
