DX Engineering Receive Feedline Voltage Injectors
DX Engineering Feedline Voltage Injectors, DXE-FVI-1, are high-quality bias-tee devices that place direct current onto a receive antenna system's coaxial cable while preventing DC from reaching the Radio port. These FVI-1 voltage injectors are used to power active accessory devices, such remote relays, switching systems, and preamplifiers. These are the original equipment FVI-1 units provided with single DX Engineering Active Receive Vertical antenna models. Voltage is applied via the 2.1mm power connector to the receive antenna feedline F connector. The RCA phono jack connects to the receiver input with that DC voltage blocked, while passing RF from 100 kHz to 30 MHz. Various RCA phono plug adapters for different RF cable connectors are available in Suggested Parts. Two DXE-FVI-1 feedline voltage injectors may be connected at opposite ends of a feedline to provide DC voltage on the transmission line for your own custom application, keeping the input and output RF devices isolated from the voltage. The included 120V AC 60 Hz wall transformer power supply may be connected to the 2.1mm power connector may to place approximately +12 volts DC on the coaxial cable center conductor, with the coaxial cable shield used as the negative ground return. A different station power supply, 1-16 VDC, may be used with an in-line, 1 Ampere, fast-blow fuse for various devices. DX Engineering feedline voltage injectors are ready for your "DC power on the coax" needs! Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. When you need to inject a DC voltage onto a 75 ohm coaxial cable used for receiving, remember the DX Engineering Feedline Voltage Injector!

QRO.cz Bias Tee Receive Feedline Voltage Injectors
QRO.cz Bias Tee Receive Feedline Voltage Injectors are engineered to inject DC voltage into a receive antenna system's coaxial cable while isolating the radio port from DC current. This allows you to power remote devices—such as preamplifiers, relays, or switching systems—without the need for separate power lines, simplifying your installation by combining RF and DC over a single coaxial feed. Typically installed at the receiving end of the coaxial cable, the bias tee passes DC power from an external source to the coax line running to the powered device. It uses a feed inductor to deliver DC to the device side and a blocking capacitor to prevent DC from reaching the radio. For added flexibility, bias tees can be used on both ends of the coaxial line to serve as DC input and output points.

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.

DX Engineering Clifton Laboratories Z10000 Buffer Amplifiers
DX Engineering Clifton Laboratories Z10000 Buffer Amplifiers may be the products most often requested by radio experimenters and electronics enthusiasts. These are the very popular circuits, designed by Jack Smith, K8ZOA (SK), that are crucial for adding a SDR receiver and panadapter display capabilities to a receiver or transceiver which lacks that feature. The Z10000 Buffer Amplifier's high-input impedance can safely tap the early-stage broadband Intermediate Frequency (IF) signal from inside your radio and feed the buffered and amplified low impedance IF signal to your external SDR receiver. It can then produce a spectrumscope - waterfall display pattern of the receiver signals on a compatible tablet or monitor and PC that is running the appropriate third party SDR software. DX Engineering offers two Clifton Labs Buffer Amplifier Kits to add an IF output SMA connector to the rear panel of your radio: * The DXE-Z10000U-KIT is the Universal Buffer Amplifier Kit that covers 50 kHz to 100 MHz. This kit is designed for those willing to do an internal modification, and will output the IF signal of virtually any receiver or transceiver that has an IF in that range. However, the DXE-Z10000U-KIT can be used as a buffer and low-gain preamp between any low level RF devices that operate in that range. As a buffer, this circuit provides over 90dB of reverse isolation to protect the IF stages of the radio from possible birdies on an SDR receiver input. So, even if your radio has an IF output connector, the DXE-Z10000U-KIT may be used externally, with a user-supplied shielded metal enclosure, to be certain to maintain proper radio operation. * The DXE-Z10000K2-KIT is the Buffer Amplifier Kit specifically tuned to the 4.915 MHz IF signal of the Elecraft K2 transceiver. It offers the same high reverse isolation, plus the added benefit of a tuned IF input with a narrower bandwidth of operation and a potentially a lower noise floor on the output. Both Buffer Amp kits contain the updated, completely assembled and tested DX Engineering Z10000C PC Board with a nominal 6.5 dB gain, retaining all the benefits of the reliable original Z10000B boards. Both kits include our finished printed circuit board, required coaxial cables assemblies with special connectors, insulating materials, and hardware—all for an easier installation than ever before! A third party SDR receiver, software (typically free) and compatible tablet or PC and monitor are required to make use of the IF signal provided by the Z10000 Buffer Amplifier and see the signals that your old radio can hear. Due to the high number of specialized radio installations, no printed instructions are included with these buffer kits. Instructional web links are found on the part detail webpages. Installation web documents and videos are only available online. The legacy that was built by Jack Smith, K8ZOA (SK), with Clifton Laboratories, lives on with select products, exclusively from DX Engineering. NOTE: DX Engineering cannot provide electronic technical support of devices installed in user radios and is not responsible or liable for damages that occur to a user radio due to improper or erroneous techniques during the installation of this product. Unplug all electronic devices when working on them and observe all electrical safety and electrostatic discharge precautions when opening sensitive electronics. Modification of a radio should only be attempted by individuals with advanced experience on electronic circuit repair and operation.
