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.

DX Engineering Receive Filter Plug-In Modules
DX Engineering Receive Filter Plug-In Modules provide frequency-specific receiving system enhancements, which fit into special DX Engineering devices listed below. These advanced plug-in filter modules are available separately to allow any user to create a specific or customized filter with low-pass, band-pass and high-pass frequency ranges. Filter cut-off and center frequencies correspond to the major Amateur bands, 160, 80, 40, 20, 15 and 10 meters, with filter module insertion loss of only about 1dB. By reducing or excluding frequency-specific interfering noise and signals, the noise floor can be lowered for the desired passband for dramatically improved reception DX Engineering Receive Filter Plug-In Modules may be installed in these devices: DXE-DMC-2 Dual Module Chassis accepts one or two filter modules to create a stand-alone passive inline filter unit of any configuration. One high pass and one low pas can be combined to create a multi-band bandpass filter of any HF range. DXE-RPA-2-PM Modular Receive Preamplifier accepts one Receive Filter Plug-In Module to customize the preamplifier passband. DXE-NCC-2 Receive Phasing Controller can accept one or two Receive Filter Plug-In Modules, one into each, Channel A and Channel B. The DX Engineering NCC-2 is highly regarded by many owners and engineers to be the best receive phasing and noise canceling unit available and is used extensively by enthusiasts in Amateur Radio DXing, Contesting, AM DXing, and Short-Wave Listening (SWL), and is also used in commercial AM and HF broadcast applications. DX Engineering Receive Filter Plug-In Modules add an extra dimension of functionality to the NCC-2, for advanced directional noise and signal nulling performance, enhanced with a specific frequency range operations. By default, NCC-2 internal option slots have bypass boards to pass all signals. Receive Filters placed into these slots dedicate the unit to filtered operation. Typically, one pair of band-pass or high-pass or low-pass filters, depending on desired filtering, is installed in the NCC-2 to suit the specific signal rejection needs of the discerning operator. As an example, an 80 meter DX enthusiast may elect to install two 80 meter band pass Receive Filter Plug-In Modules, part number DXE-R-BP80-PM, into their NCC-2 Channel A and Channel B middle slots. This dedicates their NCC-2 to 80 meter-only operations. This dramatically reduces noise and signals from outside the 80 meter band, very effectively excluding interference from nearby AM Broadcast, 160 and 40 meter stations. A much lower noise floor across 80 meters can help achieve reception of weak 80 meter DX signals. An additional pair of filters can be swapped out for a different band when desired. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. All Receive Filter Plug-In Modules displayed here are also conveniently listed on a single page linked in Documentation.

Hi-Z® Antennas DL-4 V2 Long and Short Delay Cables
Hi-Z® Antennas DL-4 V2 Long and Short Delay Cables are essential components for the Hi-Z 4 Element V2 4 Square and Hi-Z 8 Element V2 Multi-Band 8 Circle Receive Array Systems. These are the high quality RG-6U coaxial cables that are precision tuned by DX Engineering and terminated with compression-style weather resistant male F connectors. These Hi-Z DL4 V2 Delay Cables must be selected and purchased separately, depending upon the desired array band coverage and corresponding size of the array, detailed below. Each are permanently connected to the 4 Square or 8 Circle Phase Controller "Long Delay" and "Short Delay" female F connectors upon array installation. SMALL ARRAY dimensions for maximized multi-band reception require the selection of one HIZ-DL-4-60-85L (Long) and one HIZ-DL-4-60-85S (Short), as recommended by Hi-Z for: * 4 Square Array with element side spacing of 60 ft. * 8 Circle Array with a diameter of 85 ft. Overall excellent cardioid patterns are achieved for enhanced, low noise reception on all three low band bands--160, 80, and 40 meters with very good receiving results on 30 meters as well. LARGE ARRAYS that are dedicated for ONLY 160 and 80 meters, one HIZ-DL-4-80-113L and one HIZ-DL-4-80-113S are for: * 4 Square Array with element side spacing of 80 ft. * 8 Circle Array with a diameter of 113 ft. Large array spacing and longer delay cable allows the user to manipulate the achieved patterns and the resulting Receive Directivity Factor (RDF) for their desired band coverage optimization. This also requires the change of four jumpers inside the respective phase controller. See the array phase controller instructions for details on jumper settings for alternative delay lines, patterns and performance.
