I use the Studio One mic on my Jupiter and based on some audio reports
from very distant DX I have had the best luck with these settings below:



TX Filter BW: 2400
Speech Proc: 50%
TX Roll Off: 550Hz
Mic Gain: 30%
Power: 100%


I keep the mic very close to my mouth so I suspect that is why the tx roll
off is necessary that high.

But with these settings I get peaks easy at 100W output (using the
Jupiter's output on-screen meter) and the average is about 50-75.


I need to jump on the tentec net and give it a try.  Unfortunately my 40
meter dipole dishes a fair amount of RF back to the shack because of its
location but i'd like to get some reports from other tentec owners.
