Radio Patch
Radio patch is part of the Direct Enhanced Full Duplex Phone Interface and the External Enhanced Full
Duplex Phone Interface options. It allows any number of console channels to be connected to each other
allowing one group to talk to other groups through the console. The console uses voice detection to
determine which channel transmits to the others at any given time. Further, there is a delay after voice
detection ceases on a channel before the transmission is ceased on the other channels to allow for pauses
in normal speech. When a radio patch is active, other modes of operation such as paging, multi-select
and use of the phone are prohibited.
Using Radio Patch
When
RADIO
PATCH
button is pressed, the border of the button flashes red indicating that the selection
can now be edited, and the display screen changes to the Radio Patch screen. By design, no channels are
pre-selected upon entering radio patch. Channels (up to 12, if applicable) may now be added or removed
by pressing a channel
SELECT
button. When a channel is added to the patch selection, the current
frequency F1, F2, etc., is used. If a channel utilizes a channel frequency change programmable button,
this feature may be used during the selection process to alter the channel frequency for the radio patch.
Upon exiting radio patch, all channels will revert to the frequency on which they were set prior to
entering radio patch.
When the desired channels have been selected, press the main
TRANSMIT
button to establish the patch
and begin the transmission. The operator may then announce to the channels that the patch has been
established. Upon transmitting, the border indicator of the
RADIO
PATCH
button turns red indicating
that the selection can no longer be edited.
By using the main
TRANSMIT
button, the console operator is able to simulcast to all parties at any time
during the radio patch. This is similar to the multi-select feature. To talk to any channel individually,
including the radio patch channels, the channel
TRANSMIT
button must be used.
To exit radio patch, press the
RADIO
PATCH
button. Upon exiting, all channels will revert to their prior
frequency, the
RADIO
PATCH
indicator is extinguished and the information window returns to the
normal format. The last selected channel before radio patch was initiated is now displayed.
Signaling in Radio Patch
If any channel of the patch has PTT-ID enabled and the Navigator is equipped with the signaling option,
PTT-ID’s are generated on those patch channels when the
TRANSMIT
button is pressed. Additionally,
the use of a channel
TRANSMIT
button on any channel that has PTT-ID enabled causes a PTT-ID to be
generated. Decode of digital signaling still occurs on either a dedicated channel or the selected channel
as described in CARD Suite. Consult with the system supervisor regarding encode/decode of digital
signaling.
Radio Patch Alert
After the radio patch channels have been selected, it is possible to generate an attention getting alert tone
to all patch channels by pressing the
ALT
button. When the operator presses the
ALT
button, an alert tone
is generated as described previously. When the alert tone is complete, the operator can use the
TRANSMIT
button to simulcast to all patch channels.
