OOLS FOR OMFORTABLE AND
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.
Using Sloped AGC
1. To the bottom right side of the TFT, press the
[ MNU ] (Menu) key momentarily to enter the Menu
mode; the Menu will appear on the TFT.
2. Use the [ Main Tuning Dial ] knob to select Menu
Item "RX AUDIO 083 AGC-SLOPE."
3. Rotate the [ CLAR/VFO-B ] knob to change the set-
ting to "SLOPE."
4. Press and hold in the [ MNU ] key for two seconds
to save the new setting and exit to normal opera-
tion. You will now be using the Sloped AGC sys-
tem.
