Adjustment Of Rf Gain And Mu�Ng Level; Squelch Opera�On (Prior To Firmware V 1.75) - XIEGU G90 Operation Manual

Adjustment of RF Gain and Mu�ng Level
Proper RF gain adjustment can improve the quality of a received signal. In
general, reducing the RF gain level on the low bands (40/60/80/160m) which
have strong interference can significantly improve receive quality.
In general, with SDR rigs, operating at full RF gain is detrimental to receive
signal quality. Experiment with levels to find what is best for you.
How to adjust the RF gain:
1. Apply a long press on the [AGC] bu�on at the bo�om of the screen to
enable the se�ng of RFGAIN.
2. Rotate the main tuning knob to adjust the RF gain value.
3. A�er se�ng your RF gain level, press the main knob inwards momentarily
to exit the RF gain se�ng mode.

the speaker will only let sound through when the signal strength is more than
S3. Otherwise, the speaker will remain silent.
