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 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.

YCCC Vertical Array Directional Switch Console Kits
Closeout- Other YCCC array components are no longer available YCCC Vertical Array Directional Switch Console Kits were used to control the YCCC vertical array combiner/controller units, which have been discontinued. They feature an attractive cabinet with an ergonomic direction-selector knob and direction indicating LEDs. Power Pole type connectors are used for DC power connection. These kits require component-level assembly and soldering parts to a PCB. The switching console is installed in the shack, with the control cable run from the switching unit to the combiner/controller unit at the array. Power for the entire antenna system is provided by a 13.8V DC (1A capability or greater) power supply that the user must provide. Use of a "wall wart" type of power supply is not recommended because they generally have very poor DC regulation. These switch units are for use ONLY with YCCC vertical antenna arrays, which are discontinued and no longer available for sale. All inquiries and technical support for these YCCC kits and kit packages is handled by e-mail only, typically within two to three business days: yccctechsupport@verizon.net

Designed for portable operations on HF bands, these baluns let you join the fun of making a high-performance Single Band or Multi-Band Linked Dipole! This coax wound toroid achieves an amazing common mode impedance (CMI) curve, with an RF choking capability that far exceeds 'a-few-beads-on-coax' products that are offered by other suppliers, and they can handle up to 250 watts on SSB voice, or 100 watts or less on CW or Digital modes on frequencies below a 2:1 SWR. They are designed for building a center supported Inverted Vee Dipole (not end supported) and are great for use with DX Engineering Nomad Portable Telescopic Masts (sold separately). Great for POTA, SOTA and JOTA, low-cost DIY Low Power Balun Center Insulators are ready for use on a monoband resonant or link-clip multi-band resonant wire antenna for portable or long-term temporary operations. These Low Power Balun Center Insulators are the heart of the DX Engineering Low Power Portable Dipole and Winder Kits.
