or digi modes no agc helps.? Reason is that if a strong signal appears
in the pass band it pumps the agc and all signal are reduced by that
amount.? ?So a digi band has a couple of very strong signals it tends
too make the weak ones impossible to detect.? ?It was a big problem
with early receivers with a strong agc system rather than large
dynamic range.

?described differntly AGC when it operated it does so by
making the radios gain lower to correct the excessive
level.? Good for the ears but it also is making the radio
less sensitive to accomplish that.
