2.8.2.8 RT - Squelch Threshold (RT SQL_LEVEL)
Display Contents
Configuration Mode (RT6512)
Squelch threshold level ("RT SQL_LEVEL")
The noise squelch threshold "RT SQL_LEVEL" is adjustable in a
range of 6...23. Use the rotary encoder for adjustment.
•
Minimum adjustment of 6
(very weak signals are audible with high noise content; squelch
opens at about -105 dBm)
means:
o
Weak RF signals can trigger the squelch threshold.
o
The voice signal might be low combined with a noisy
background.
•
Maximum adjustment of 23
(only quite strong signals are audible with low noise content;
squelch opens at about -87 dBm)
means:
o
Only strong RF signals will trigger the squelch threshold.
o
The voice signal will be audible very clear with very low
background noise.
o
Weak RF signals may not trigger the squelch threshold and
therefore the audio may not be heard by the pilots.
Notice:
For very weak RF signals receiver audio level might be reduced.
2.8.2.9 RT - Sidetone (RT SIDE_LEVEL)
Display Contents
Configuration Mode (RT6512)
Sidetone level ("RT SIDE_LEVEL")
The attenuation relates to the received volume setting.
•
0 dB = sidetone as loud as received signal.
•
12 dB = sidetone signal 12 dB less than the received signal.
