Sloped Agc Operation; Mute Feature (Main (Vfo-A) Band) - Yaesu FT-2000 Operating Manual

T
OOLS FOR
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-2000D, however, includes an innovative Sloped AGC sys-
tem on the Main band (VFO-A) receiver, that allows the audio volume to
rise and fall slightly according to signal strength. Although the rise/fall slope
is not dramatic, it is 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. Press the [ MENU ] button momentarily to enter the
Menu mode.
2. Use the Main Tuning Dial knob to select Menu item
"088 rout AGC SLP."
3. Rotate the [ SUB VFO-B ] knob to change the set-
ting to "SLP."
4. Press and hold in the [ MENU ] button for two sec-
onds to save the new setting and exit to normal op-
eration. You will now be using the Sloped AGC
system.
There may be occasions, during Dual Receive operation, when you want to silence the Main (VFO-A) receiver tempo-
rarily so as to concentrate on what's being received on the Sub (VFO-B) receiver. The Mute feature makes this simple to
accomplish.
Press the Main [ RX ] LED/switch. The Main (VFO-A) re-
ceiver will be silenced, and the green LED in the [ RX ]
switch will blink.
To restore reception on the Main (VFO-A) receiver, just
press the blinking [ RX ] switch/LED once more.
A :
If you press the [ POWER ] switch momentarily while the
transceiver is turned on, the transceiver's audio will be
muted for three seconds.
