In traditional AGC systems, the audio output from the
transceiver becomes essentially fixed once the thresh-
old for AGC action is reached (usually several dozen
dB above the no-signal noise floor). The FT DX 9000,
however, 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 dtamatic, 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 to select Menu Item RX
AUDIO 075 AGC-SLOPE; you may also use the
[F6] () and [F7]() jkeys to select the above
Menu item.
3. Rotate the CLAR/VFO-B knob to change the set-
ting to “SLOPE.” Alternatively, you may use the
[F4] () and [F5]() jkeys to change the setting
the setting 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 wil now be using the Sloped AGC sys-
tem.
