Sloped Agc Operation - Yaesu FT DX 9000MP Operation Manual

In traditional AGC systems, the audio output from the transceiver becomes essentially fixed once the threshold for
AGC action is reached (usually several dozen dB above the no-signal noise floor). The FT
includes an innovative Sloped AGC system, that allows the audio volume to rise and fall slightly according to signal
strength. Although the rise/fall are not dramatic, they are sufficient to allow you to use your ear to discern and
separate signals according to signal strength, not just audio frequency.

the Menu mode; the Menu will appear on the LCD

tion. You wil now be using the Sloped AGC sys-
tem.
