DXE-RTR-2 Modular Receive-Transmit Interface

RTR-2 Modular Receive-Transmit Interfaces provide the easiest and safest method for connecting a dedicated receive antenna to an HF transceiver that does not have a separate receive antenna input.

Placed inline with the transceiver's antenna connector, the RTR-2 does the job of a 200 watt T/R relay using the amplifier keying line for failsafe protection, so your transmitted energy cannot go to the receive antenna.

Three internal Plug-in Module option slots provide added features and protection

• DXE-RPA-2-PM Receive Preamplifier Plug-in Module
• DXE-TRI-PM Transmit Receive Interrupter Plug-In Module
• DXE-IT-PM 75 to 50 ohm Impedance Transformer Plug-in Module

Features

• New Status Indicating Color-changing LEDs
• Three internal slots for new DX Engineering modules
• New Key Line Out connector for Amplifier
• New internal jumper for placing DC on the Receive Antenna feedline for Active or Loop receive antennas
• Attractive and heavy stainless steel enclosure
• 200 watts RF switching capability
• Main transmit antenna connector is SO-239 (UHF female)
• Radio RF connector is SO-239 (UHF female)
• Receive antenna input is 75 ohm F connector
• Receive outputs are standard 75 ohm Type F connectors
• Inputs are 50 ohm BNC or 75 ohm F (Optional transformer module available)
• Safe switching-transmit antenna is always connected to transceiver on power-off
• Hot switching lockout-disables receive antenna during transmit mode (Optional DXE-TRI-PM can be set to short the RX ANT line)
• Versatile-allows inclusion of Optional RF preamplifiers and other plug-in modules
• Simple 13.8 Vdc input for all operations
