Hmmm... I didn't realize the DVP has a wider IF. I gather DVP requires up to 6

I'm getting about 0.35 for 12 db SINAD. But that looks about 10 db quieting to
me. What I typically do is open the squelch with no signal and set the volume
to 2 Vac then crank up the signal to 0.2 vac. Isn't that 20 db, or am I missing
something?

In that spirit. Going from 80 to 100 watts is 0.97 db better. That's probably
not an improvement your users will notice. When one considers what a pain it is
when the PA dies, it might not be worth it. Just my 2 cents but I think you're
better off leaving the amp at 80 watts.

The Micor book says less than 0.5 uV for 20db quieting or 0.35 for 12 db SINAD.
So the two are in fact equivalent. I get better than 0.35 for 12 db SINAD but I
don't measure 0.5 for 20 db quieting. I must be doing something wrong.
