Pc Control; Usb Interface; Usb Driver; Clock - AOR AR5001D Operating Manual

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 no is e espe cially d uring
pauses in speech or inactivity.
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.
