RTR-2
. An external Receiver Guard
DXE-RG5000HD
is recommended. Only the main transceiver
may be used to transmit. The second transceiver that is connected to one of the
DXE-RSC-2
outputs must be transmit inhibited using either the radio's menu settings or power output controls
set to zero to prevent system damage.
Set the
MAIN ANT - RX ANT - MAIN ANT
toggle switch to the
RX ANT
(center) position to
connect the
MAIN ANT
to both radios for simultaneous reception. When you key the main
transmitter, the
DXE-RTR-2
automatically changes from receive on both radios to transmit on the
MAIN ANT
in about 4 ms. The strong signal heard by the second radio is at a level that cannot
damage it's front end. An external relay may be required to mute the second receiver supported on the
RTR-2
ACC PTT
. Manually switching the toggle switch to the
MAIN ANT
(up) position connects
the
MAIN ANT
to the main transceiver, if desired for tune up operations, or for normal operations
without the second radio.
The power limit for the radio transmit is 200 watts
.
Diagram 10
illustrates how to share the transmit antenna with two radios such as a Kenwood
transceiver and an SDR with a spectrum display. Similar to Diagram 9, using the
DXE-KWD-RTR
Keying Cable. Addition of an external Receiver Guard
DXE-RG5000HD
to protect the second
receiver is left to the discretion of the user. Any RTR-2 internal optional Plug-in Modules are ‘seen’
only by the Kenwood transceiver (in this diagram) connected to
RADIO
. Use the
ACC PTT
(and
external relay if needed) for the second receiver mute during transmit,
