Talking on 75 meters right now. AGC-T @ 40 AGC set to Slow Pre-amp set to high If I don't look at the meter, I can't tell the difference in peoples audio if I don't look at the signal levels on the meter which when I look are varying more than 20 db .
The band is very very noisy with your settings here in Texas. It's very melodious and quite with mine. Do you guys actually ever use your radios? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dale Boresz Sent: Monday, May 05, 2008 7:40 AM To: Robert Dennison Cc: flexradio@flex-radio.biz Subject: Re: [Flexradio] AGC Rob, One of the great things about PowerSDR is that you can so easily adjust the AGC threshold to accomodate band conditions. Remember though, the lower the AGC-T setting number, the less the AGC will be compressing the audio gain, therefore, the greater the audible difference in amplitude between weak and strong signals, and the lower the background noise between signal peaks. If you increase the AGC-T setting to something more like 75 or 80, the effective audio gain compression is increased considerably, (at the expense of hearing more band noise relative to signal levels), and the differences between weak and strong signals will become much less. Overall it's a noisier listening experience, but you won't be jolted by the big signals. 73, Dale WA8SRA Robert Dennison wrote: > Sheesh, > > Just got my ears blasted out by a S9++ sig.
