DX Engineering Receive Filters
DX Engineering Receive Filters are available individually for use in the NCC-2, RPA-2, RTR-2 or DMC-2 with adapter boards. These filters are also available in sets with mounting fixtures for use in the NCC-1. DX Engineering Receive Filters are numbered for the key Amateur Band on which they function. The Band Pass filter models pass RF only on the numbered band, the High Pass models function on that band and all device frequencies above, and the Low Pass models work on that band and all device frequencies below. Response plots for Receive Filters are conveniently listed on a single page in this product's detail web page tab labeled "Charts and Guides". Some users will want to use a pair of these filters with two of the required DXE-RXFL-1 Filter Adapter Boards in their NCC-2. Each individual filter used requires a DXE-RXFL-1 Single Filter Adapter Board to convert them for installation in DX Engineering device models DXE-NCC-2, DXE-RPA-2, DXE-RTR-2 or DXE-DMC-2. All of the RXFL filters are still available in paired sets including two filters and one filter mounting fixture for owners of the legacy NCC-1 unit. See the Receive Filter Sets in combo packages by entering NCC-1 into the search box above.

DX Engineering Transmit Receive Interrupter Plug-In Module
DX Engineering Transmit Receive Interrupter Plug-In Module, DXE-TRI-PM, provides essential protection from the station's transmitted energy picked up by a receive antenna that is connected to the DXE-NCC-2 Channel B Receive Antenna Input active front end. This optional custom PCB relay switch device is typically installed in the top Option Slot of the Channel B rear panel board in the NCC-2. When the transceiver keys the RADIO PTT port of the NCC-2, the DXE-TRI-PM can open or ground the receive antenna input and the board output, as selected by jumpers. It functions independently and does not affect or depend on the settings of the NCC-2 Bias-Tee Enable circuit that places DC on the receive antenna feedline for Active antennas. The DXE-TRI-PM is only in the path of the receive antenna input. It also features a Gas Discharge Tube to protect the front end of the NCC-2 while in the receive mode. Adding a second DXE-TRI-PM Transmit Receive Interrupter Plug-In Module to the the top slot of the NCC-2 Channel A rear panel board is recommended. The gas tube provides pulse energy protection during receive and disconnect or grounding protection when the CH A RX ANT IN port is used for a receive antenna that is physically too close to the transmit antenna. Adding a DXE-TRI-PM can provide input protection for the RTR-2 RX ANT IN during receive and by grounding the receive antenna input during transmissions. Alternatively, the DXE-TRI-PM installed in the DXE-DMC-2 Dual Module Chassis can interrupt or ground any receive antenna feedline or a receiver input. Jumper settings select opening or grounding of the receive antenna input and receiver output. This receive feedline RF switch is operated by toggling 13.8 VDC, on for Receive and off when Transmitting. The DMC-2 PCB jumper HD5 selects operating DC from either the 2.1mm power connector or the "Receiver Output" coaxial cable with a user supplied DC Bias-Tee device, such as the DXE-FVI-1 Feedline Voltage Injector. Remote outdoor installation requires a weather resistant cover.
