That is why I first ask how the transceiver behaves when connected to a
dummy load.
Even that is not conclusive because there is always the possibility of a
faulty coax between the transceiver and the dummy load, but it does
usually rule out a fault in the transceiver and force attention to the
antenna system.
Bad connections in the antenna system can cause all kinds of 'strange
happenings'.

I estimate that something over 90% of all the problems I have had with rigs
over the years not performing up to spec came from from bad coax and
connector installation. That's the first thing I suspect now. Goofy tune
up, weird SWR readings, lo-no output, poor signal reception, hair loss and
gout, all from bad connectors and bad coax!
It's not always that, of course, but it has been the first place to start
looking, and testing every part of the feed line from S0-239 to driven
element!
