Got on HF for the first time in a couple of months and made a few contacts but my radio's output didn't seem normal. Changed bands and the radio wouldn't even tune ones it should tune easily on my EFHW.
The NanoVNA reported high SWR as well.
I'll need to find a day when I feel patient enough to try to track this down. One of the first steps will likely be to remove the lightning arrestor in case it is to blame. But I can imagine any of a number of culprits.
