Dear Fellow Elecraftists,
I have been adjusting/measuring many HF rigs the last 10-15yrs or so,
using a calibrated Marconi generator.
From what I've found on S-meter accuracy, I conclude there is no such
thing as the "6 dB per S-unit". Offical tests in magazines and books
verify this too.

Well here's my 2 cents...
I work almost 100% QRP. The person who copies my signal might be doing the

You cannot make a sound judgement using TUNE. Evaluate the R98 value change

to that.

Since you are reducing the setting of the AF gain control when changing from
