Icom IC-R9500 [44/194] Rf gain adjustment
Volume setting
Rotate [AF] control clockwise to increase, counter-
clockwise to decrease the audio output level.
Set a suitable audio level.
RF gain adjustment
Rotate [RF] control clockwise to increase, counter-
clockwise to decrease the receiver sensitivity.
NOTE:
When [RF] control is adjusted CCW in FM mode,
audio output decreases then disappears. This is
normal, not a malfunction.
When WFM mode is selected, RF gain is fixed
MAX regardless of any [RF] control settings.
Squelch level adjustment
The squelch disables output from the speaker (closed
position) when no signal is received.
When no signal is received, rotate [SQUELCH] con-
trol fully counterclockwise first, then rotate
[SQUELCH] clockwise to the point that the noise
just disappears.
Push and hold [MONI] to open the squelch temporarily.
