6.5. Squelch control (SQ)
The AE 6491 ANC features 3 different squelch systems:
• Automatic squelch (ASQ)
• Manual squelch
• Tone squelch (CTCSS)
All of them are masking the noise of the channel by muting the
speaker. Only when certain criterias are met, the squelch is
opening the speaker so the received signal can be heard.
6.5.1. Automatic Squelch (ASQ)
The ASQ is constantly checking the noise level on the channel.
Once a signal is received, the noise level reduces and the ASQ
opens. Pressing the ASQ button activates or deactivates the
ASQ function.
The current status is indicated by the ASQ symbol in the display.
The ASQ can be adjusted in 3 levels, level 1 has the highest
sensitivity.
