I have to agree with you Lou… I’m seeing the same problem. I got concerned when I got no RBN report, or response from my CQ. So I measured input voltage and output power.

When I bring the supply voltage up to about 11.8 Vdc, I only see about 2.5 W out on 40m. I’m pretty sure I used to see closer to 4 W output with that same supply voltage.

I’ve accidentally transmitted for brief periods without all the band switches aligned, but if that’s all it takes to fry the radio, I need to find something else.
