Lineout The output source determines where the
received audio is output.

Line : Output audio on the 600
ohm line interface

Speaker: Output audio on the
integrated speaker.

Headphone: Output audio to a
headphone connected to the front
panel connector.

VoIP : Output audio on the IP
interface (availability depends on
radio specifications).
Audio Line output level -40
– +10 dBm
1 dB steps
-10 dBm The max. output level on the 600 ohm line
output.
Audio RF AGC Off, x-fast, fast,
norm, slow, x-
slow Norm Set the attack and release times for the RF
AGC

Off is used only for maintenance
purposes.
Audio AF AGC On | Off Off Set the automatic AF gain control on or off.
Setting AF AGC on will lead to constant
audio output when received signals have
varying modulation levels
Audio Mute on transmit On | Off On Set this to On if the receiver should be
muted while transmitting. Requires that the
Tx busy signal on the RX connector on the
transmitter is routed to the TX busy input on
the receiver REM connector.
Squelch Override level -10 dBuV to +30
dBuV 20 dBuV The override level where the analogue
squelch will open even if it is a “noisy”
signal. This squelch level overrides the
noise compensated squelch. Setting this
level to a lower level than the “SQ level” will
disable the noise compensated squelch
completely.
Squelch Inband config Off, open,
closed, both Off Defines the behavior of the inband squelch
signal.

Off : No inband tone is generated

Open: An inband tone is
generated when the squelch is
open (receiving)

Closed: An inband tone is
generated when the squelch is
closed (muted)

Both: Different tones are
generated depending on the
status of the squelch.
Squelch Inband freq open 100
– 5000 Hz
1 Hz steps
5000 Set the frequency to be used for the inband
tone that will be used to signal that the
squelch is open. Requires that
open is
included in the Inband config setting. The
receiver will automatically notch the received
signal and insert a tone at the given
frequency.
Applicable to the line interface output only.
Squelch Inband freq closed 100
– 5000 Hz
1 Hz steps
5000 Set the frequency to be used for the inband
tone that will be used to signal that the
squelch is closed. Requires that closed is
included in the Inband config setting. The
receiver will automatically insert a tone at
the given frequency.
