The normal position for the AR5001D RF gain control is fully counterclockwise when set at its most

sensitive. As the control is rotated clockwise, the S-meter will advance to indicate what strength signal is

required to produce solid and readable results.

The control is most useful on SSB most where RF gain should be adjusted so that the peaks of SSB

signals just deflect the S-meter. This will greatly reduce the level of background noise especially during

pauses in speech or inactivity.

Note: RF gain control is not available in FM mode.

Before using the RF gain control, the AGC must be set to off.

To activate RF gain control, press the [FUNC] key, and then press the [6] key.

To change RF gain, rotate the squelch knob.

To de-activate RF gain, repeat above steps.
