If Talkaround is enabled on a channel, that channel will operate in
Talkaround mode unless the Toggle Switch is programmed for Direct/
Repeat operation and is set in the Repeat position.
Note: On HT 1000 and JT1000 models, using the Talkaround field
in conjunction with the toggle switch is quite useful.
Talkaround is incompatible with both PTT-ID and MDC RAT in that these
data transmissions will be inhibited on channels where the
Talkaround field is enabled. Enabling Talkaround is not necessary if it
is acceptable to program the transmit and receive frequencies to the
same value (such that no Repeat mode is possible). This is how
Talkaround is achieved on VISAR radios.
Note: If you want to have PTT-ID or MDC RAT on a simplex channel,
program the Tx and Rx frequencies to be the same and disable
Talkaround.
The default is Disabled.
Rx Only Channel Use the UP/DOWN arrow keys to enable/disable this feature. Enabling
this option prevents the radio from transmitting on the current
channel. A continuous alert tone will sound when the PTT button is
pressed, indicating to the radio user that this is a receive-only channel.
Other transmit-related fields are hidden when this field is enabled.
The default is Disabled.
Tx Inhibit on Busy Chan Use the UP/DOWN arrow keys to enable or disable this field. Enabling
this field will prevent the radio from transmitting on a receive-PL
channel which has activity. For this feature to operate correctly, the
following conditions must be met:
• The Receive Squelch field (on this screen) must be set to PL, DPL, or a
combination of PL or DPL and Quik-Call II;
• The DPL/TPL Code field (on this screen) must have a have a frequency
specified; and
• The Clear Channel Definition field (on the SYSTEM CONFIGURATION
screen – F4/F4) must be set properly, to either Matched PL or No Carrier.
The Clear Channel Definition field determines what channel conditions
are considered “Busy” and “Clear” so that Transmit Inhibit on Busy can
operate as desired.
If the Quick-Key Override field in the SYSTEM CONFIGURATION
screen (F4/F3/F2) is enabled, the Transmit Inhibit on Busy can be
overridden by pressing the PTT switch again within one second of the
first press.
The default is Disabled.
