4.7 Receive (Listen) Operation
After turning the radio ON the automatic squelch is either ON or
OFF depending on SQ knob
2
position.
Squelch ON means that without received signal the receiver
noise is blocked, the TX/RX LED
4
is clear. When normal signals
are received, the TX/RX LED
4
turns to green; weak signals and
interfering pulses are disabled.
Set the RX volume of the built-in loudspeaker
9
or earphone to
a comfortable level by rotating the VOL knob
1
.
Weak signals can be received if the squelch circuit is switched
OFF by rotating the SQ knob
2
fully counter-clockwise. Then
typical RX noise is continuously heard during communication
breaks.
Rotating the SQ knob
2
more clockwise switches the squelch
circuit ON again.
DO NOT press the PTT (Push-To-Talk) key if you want to receive!
During RX the TX/RX LED
4
must not light RED or flicker
YELLOW!
This radio contains an audio-leveling circuit. So if you change the
frequency or you receive another station you should get an almost
constant audio volume (the received signal must be at least
modulated by 30% AM).
IMPORTANT!
Switching OFF the Squelch only makes sense if long range
reception shall take place. Thus the radio is noisy during
Standby operation, but no weak signals are suppressed and
the full receiving range is available!
Notice increased current consumption when battery operated!
