Overview

DX Engineering NCC-1 Receive Filter Sets

DX Engineering announces a series of NCC-1 Receive Filter Sets, a breakthrough option for owners of the NCC-1 Receive Antenna Phasing Unit. These advanced plug-in filter module sets offer frequency-specific receive antenna system enhancements for the NCC-1.

All filter modules sets are available in matched pairs of 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 1 dB.

Highly regarded by many owners and engineers to be the best receive phasing and noise canceling unit available, the DX Engineering NCC-1 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 NCC-1 Receive Filter Sets add a new dimension of functionality to the NCC-1, for advanced directional noise and signal nulling performance, enhanced with specific frequency range operations. By default, NCC-1 filter slots are jumpered to pass all signals. On the NCC-1 front panel, the BAND toggle switch "L" or "H" positions each activate one of two filter pair slots, allowing over 360 degrees of phase rotation in two frequency ranges. The BAND switch "L" position covers from 850 kHz to 8 MHz. The BAND switch "H" position covers from 2 MHz to 15 MHz. Frequencies outside these ranges will have less than 360 degrees of phase rotation. NCC-1 Receive Filter Sets must be placed into the proper BAND filter slots corresponding to desired usage.

NCC-1 Receive Filter Sets are pairs of filters (2 of the same type), so both NCC-1 receive antenna inputs "A" and "B" exhibit the same pass-band characteristics. Band-pass, high-pass or low-pass filters are available for users to choose and install into their NCC-1 for their desired application. By reducing or excluding frequency-specific interfering noise and signals, the noise floor of the desired pass-band can be lowered for dramatically improved reception.

You can install one set or two sets, depending on your desired filtering. NCC-1 "L" and "H" slots may be populated with pairs of band-pass, high-pass, or low-pass filters 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 NCC-1 Receive Filters, part number DXE-NCCFL-BPF80M, into their NCC-1 "L" BAND slots. This would dedicate their NCC-1 to 80 meter-only operations. Setting the BAND switch to "L" would dramatically reduce 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 on 80 meters could be achieved for dramatically enhanced reception of weak 80 meter DX signals. An additional pair of filters could be installed into the "H" BAND slots, to enhance reception on the higher HF bands. For example, installing 20 meter high pass filters, part number DXE-NCCFL-HP20M, and switching to BAND H would drastically reduce all received noise and signals from frequencies below 13.70 MHz. With advanced planning of additional filter availability, an NCC-1 owner could even swap different filter sets for optimal operations in different contests or band pursuits.
