BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - ADVANCED OPERATION
Each mute type has two primary
mute states: Enabled or Disabled.
However, the Enabled state can be
either open or closed. Each of these
states is further described below.
Enabled and Closed: No trans-
mission audio is currently being
detected by the transceiver. No
sound is heard.
Enabled and Open: Transmission
audio has been detected by the
transceiver. This state is tempo-
rary and will automatically revert
to mute Enabled and Closed state
once audio is no longer detected.

“hardness” of the voice mute and
its sensitivity to voice activity on a
channel.

level at which the mute (squelch)
opens. When set to low, the mute
will open on a relatively low level of
received signal. For high, the mute
will open for a relatively high level
of received signal.
