Receiver Quieting, or Tone Squelch (TSQ), is actually SELCALL in action. When
activated, the UH-088 receiver is muted and you cannot hear any signals until the
mute is disengaged by reception of your Selcall code.
Refer to page 8 for explanation of how the squelch system works.
The Squelch discussed previously "screens“ the received signal level, however in
tone squelch mode, the squelch monitors the signal for your ID.
Tone squelch (Receiver Quieting)
1. The Tone Squelch Control acts as an electronic lock. Activating the Tone squelch
closes this lock.
Regardless of how strong the received signal is, if it does not have the required
"electronic key" the gate will remain closed.
2. If the received signal contains the required key (which is your Radio ID), this
electronic lock will open.
The muting circuit is then deactivated on your radio and advises you that a call has
been received.
