DXE-RTR-1 Receive Antenna Interface for Transceivers - N3UJJ

MAIN ANT INSO-239 connector - RF connection to a suitable transmit antenna or load. Connected, bydefault, to the RADIO connector when the DXE-RTR-1 is not powered or the MAIN ANT/RXANT switch in the MAIN ANT position. Connection for high end transceiver "RX OUT" tomonitor transmit antenna through DXE-RTR-1. Details in Diagram 1B and text. MAIN ANT OUTRCA type connector and F-Connector (in parallel) - Output for special applications, receiveonly connection of MAIN ANT during receive mode only. Used for transmit antennamonitoring and pre-amplification or phasing purposes only. Disconnected during transmit orwhen unit is switched to MAIN ANT. See Diagrams 5 and 8. RX ANT INRCA type connector and F-Connector (in parallel) - Input for receive only antenna, or from areceive only device. May accept output from a DXE-RPA-1 Receive Preamplifier, or from aDXE-NCC-1 Receive Antenna Variable Phasing Controller. 12 VDCA 2.1 mm power cord is supplied with unit. The wire with the white stripes is the +12 Vdc.Outer Connection is GROUNDCenter Pin is +12 VDC.If station power is used, it must be +12 Vdc at 1 amp (fused) minimum. An optionalDXE-PSW-12D1A 120 Vac 60 Hz to 12 Vdc 1 Amp, fused wall transformer supplyis available.Internal JumpersThere are two internal jumpers set to factory default positions. HD1 and HD2 are jumpered bydefault to the top two pins towards the HD1 and HD2 lettering on the printed circuit board forproper operation as shown in Figure 3. HD1 and HD2 are reserved for possible future options.Connection DescriptionsFigure 3 - Internal Jumpers HD1 and HD2The diagrams included in this manual demonstrate the wide variety of specific connections that arepossible with the DXE-RTR-1, truly a multi-purpose device. These connections are simple andstraightforward and do not require advanced electronics skill.9From The N3UJJ.COM Document Library
