OK. I'll accept that. However, let me add that if you consider the
average stock exciter, is the same still true?
 
No, theoretical and practical can be very different...   :-)
 
But it's good to discuss both. Maybe some new ideas will hatch!
 
 

Again, some people have more
experience at interfacing controllers and repeaters. for some people,
the best answer is to use de-emph/pre-emph - especially if they don't
want to dig into the guts of their radio.
 
The board being discussed on this list with the high-order filter and the limiter, assuming it's designed right, would be an excellent addition to the repeater builder's arsenal. Replace the 'blob' and get around the soft limiting and the other problems. We talked about doing such a board here, but doing a universal version for many different repeaters would take serious time. It'll be interesting to hear the results.

Me, too! Thanks!
