Conventional Mode Features
5.7 Repeater Talkaround
Normally, all transmissions go through a repeater which usually increases range.
However, there may be times when a user is out of range of the repeater and therefore
unable to talk to anyone even though the user being called is only a short distance away.
To allow communication in this situation, repeater talk-around can be selected.
Transmissions then occur on the receive frequency which permits direct radio-to-radio
communication.
Repeater talkaround can be selected if the TA option button or “Talk Arnd” menu
parameter is programmed. When talk-around is enabled by this button, is displayed.
This feature remains enabled during scanning, and changing channels or turning power off
does not change the selected condition. Talkaround is available on conventional channels
only.
A function button can be programmed to the “Repeater Talkaround” function. With a
button programmed as “Repeater Talkaround”, the user can press this button while on any
conventional frequency, shifting the radio from operation through a repeater, to simplex
operation on the repeater transmit frequency.
With a “Repeater Talkaround” button enabled, there is no restriction as to which channels
the user can transmit (in simplex mode) on the repeater transmit frequency. A user can
switch to talkaround mode on a busy dispatch channel, and his transmissions could
prevent nearby users from hearing the repeater transmissions.
5.8 Displaying Transmit / Receive Frequency
If the Displayed Information option button or menu parameter is programmed (see Section
4.2, "Option Keys / Buttons"), it can be used to display the channel frequency in
megahertz. Pressing this button toggles between displaying the standard channel alias and
the channel frequency. The receive frequency is displayed when receiving and the
transmit frequency is displayed when transmitting. This feature is available on
conventional channels only.
