I have been using 3 to 31MHz as my span as you will see these dancing deverishes darting in and and out of the lower end

I got better results by replacing C22 with filter and leavening R27 intact!
Have a nice meeting and catch you later!

It turns out I did have time for one pass of spur measurement. Here are screens for each of 17 through 10 meters. Conditions of the test: Audio input: 100 mVrms, 1.5 kHz tone. RV1 adjusted in each case for 2 watts output.
