Voice Communications (SSB and AM)

When transmitting in SSB or AM mode

The FT-710 transmit audio circuit can be set to the optimum operating level by individually adjusting the
input and output gains of the microphone amplifier.
The AMC (Automatic Microphone Gain Control) regulates the microphone audio so that distortion does not oc-
cur, even if excessive audio is input.
1. Adjust Microphone gain
Touch the Meter Display and then touch "ALC" to
select the ACL Meter.
1. Press the [FUNC] knob.
2. Touch [MIC GAIN].
3. Key TX and adjust the [FUNC] knob to set the
input level of the Microphone Amplifier to the
position where the ALC Meter needle does
not exceed the ALC zone on the audio peaks.

Set with the FUNC knob

Operate the [FUNC] knob to make the following settings.
PROC LEVEL: Adjust the level of the speech processor function.
RF POWER: Adjust the transmit power.
MONI LEVEL: Adjust the monitor level.
The last function used is retained in the [FUNC] knob so it can be easily set by operating the [FUNC]
knob. Normally, it is suggested to utilize the [FUNC] knob as the [LEVEL] knob for the spectrum scope.
