Squelch attenuator
The transceiver has an RF attenuator related to the squelch
level setting. Approx. 10 dB attenuation is obtained at maxi-
mum setting.
The squelch attenuator allows you to set the minimum signal
level needed to open the squelch. The attenuator function can
be deactivated in FUNC set mode (SET).
