RADIO
SO-239 connector - Transmit and receive RF connection to the transceiver or connection to
transmitter RF connector. Maximum 200 Watts transmit with MAIN ANT connected to a
suitable antenna or load. Connected, by default, to the MAIN ANT IN connector when the
DXE-RTR-1A
is not powered or the MAIN ANT/RX ANT switch in the MAIN ANT position.
MAIN ANT IN
SO-239 connector - RF connection to a suitable transmit antenna or load. Connected, by
default, to the RADIO connector when the
DXE-RTR-1A
is not powered or the MAIN
ANT/RX ANT switch in the MAIN ANT position. Connection for high end transceiver "RX
OUT" to monitor transmit antenna through
DXE-RTR-1A
. Details in
Diagram 1B
and text.
MAIN ANT OUT
RCA type connector and F-Connector (in parallel) - Output for special applications, receive
only connection of MAIN ANT during receive mode only. Used for transmit antenna
monitoring and pre-amplification or phasing purposes only. Disconnected during transmit or
when unit is switched to MAIN ANT. See Diagrams 5 and 8.
RX ANT IN
RCA type connector and F-Connector (in parallel) - Input for receive only antenna, or from a
receive only device. May accept output from a
DXE-RPA-1
Receive Preamplifier, or from a
DXE-NCC-1
Receive Antenna Variable Phasing Controller.
12 VDC
A 2.1 mm power cord is supplied with unit. The wire with the white stripes is the +12 Vdc.
Outer Connection
is
GROUND
Center Pin
is
+12 VDC
.
If station power is used, it must be +12 Vdc at 1 amp (fused) minimum. An optional
DXE-PSW-12D1A
120 Vac 60 Hz to 12 Vdc 1 Amp, fused wall transformer supply
is available.
Internal Jumpers
There are two internal jumpers set to factory default positions. HD1 and HD2 are jumpered by
default to the top two pins towards the HD1 and HD2 lettering on the printed circuit board for
proper operation as shown in
Figure 3
. This jumper configuration is used to take advantage of the
Level Limiter circuitry to help prevent receiver overload damage. HD1 and HD2 are reserved for
possible future options.
