TOOLS FOR COMFORTABLE AND EFFECTIVE RECEPTION

AGC (AUTOMATIC GAIN CONTROL)

SLOPED AGC Operation

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

MUTE FEATURE (MAIN (VFO-A) BAND)

There may be occasions, during Dual Receive operation, when you want to silence the Main (VFO-A) receiver temporarily 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) receiver 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.

ADVICE:

If you press the [POWER] switch momentarily while the transceiver is turned on, the transceiver’s audio will be muted for three seconds.
