[Flexradio] AGC

[Dale Boresz]

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.
