Operation
Once all connections have been made and double
checked, turning PWR on the
DXE-RTR-1A
will
illuminate the green LED.
The three position MAIN ON - RX ANT - MAIN ON
toggle switch for manual control of the
DXE-RTR-1A
antenna selections.
MAIN ON
(toggle switch up)
Manually switches the transceiver (RADIO) to the MAIN ANT for receiving with the
transmitting antenna. The transceiver will remain connected to MAIN ANT during transmit.
The red LED will not illuminate.
RX ANT
(toggle switch center)
Place the switch in this position for reception with a receive antenna. This position connects
the RADIO to the RX ANT for receive mode on a receive antenna and allows automatic
switching of the RADIO to the MAIN ANT during transmit. The red LED will illuminate
only during receive with the receive antenna and will extinguish when the transceiver
switches to transmitting.
MAIN ON
(toggle switch momentary down)
Manually switches RADIO to MAIN ANT momentarily for a fast check of reception on the
transmitting MAIN ANT.
Manual Updates
Every effort is made to supply the latest manual revision with each product. Occasionally a manual
will be updated between the time your DX Engineering product is shipped and when you receive it.
Please check the DX Engineering web site (www.dxengineering.com) for the latest revision manual.
Note:
If the keying line is shared (using a "Y" adapter) with an amplifier or amplifier interface buffer, then
precautions should be taken to be certain that the transceiver to
DXE-RTR-1A
connection is not
interrupted.
If the keying line connection from the transceiver to the TRANSMIT GROUND connector on the
DXE-
RTR-1A
is lost, transmitted RF may cause damage to the
DXE-RTR-1A
or receiving equipment.
The TRANSMIT GROUND keying line connector
MUST
be connected to a
grounded-on-
transmit
transceiver keying line, cable shield to radio chassis ground, and the RADIO connector
must be connected to the transceiver RF connector, cable shield to radio chassis ground, to enable
receive mode.
Positive voltage keying will not key the
DXE-RTR-1A
properly.
Damage to the
DXE-RTR-1A
could occur by attempting to use positive voltage keying. Review
your transceiver operation manual carefully. Transceivers with positive keying only must be
connected to an interface buffer to provide grounding-on-transmit keying.
