TRANSMIT GROUND
Isolated RCA connector - Keying line connection from transceiver or sequencer (grounding
keying line only) for automatic relay switching of RADIO from the RX ANT IN to the MAIN
ANT. This connection to the transceiver is required to enable reception on a receive antenna;
RX ANT through to RADIO with front panel MAIN ON/RX ANT switch in RX ANT position.
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.
This connector
MUST
be connected to the
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.
