Good point, Victor. And why I included that SWR reading. Other bands read fine. I have high confidence in the load and adapter (tried swapping both just in case). I could measure the load and adapter the next time I'm in the lab at work if I want to be absolutely thorough, but it is a microwave load and just adapting from BNC to N (no coax).
SWR looks fine on other bands.
