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.

SOTAbeams Fuser 6 DC Distribution Boxes
SOTAbeams Fuser 6 DC Distribution Boxes are the lightest PowerPole® distribution boxes… by far! SOTABEAMS PowerPole® Fuser-6 boxes make light work of connecting five accessories to your power source (they have one input and 5 outputs). All of the connectors are individually fused. In a typical shack you might have a 100 Watt HF radio, a 50 watt 2m FM radio, an antenna tuner and a QRP rig all connected to your Fuser-6 - and still have a spare connector! Fuser-6 boxes are supplied with three 25 Amp and three 5 Amp fuses. Standard automotive blade fuses make replacement easy - these are widely available with values from 1 to 30 Amps. Fuser-6 units incorporate a polarity warning system; lights GREEN for CORRECT and RED for REVERSE. It's handy when you have a battery connected to the system to help avoid damage to your equipment if you accidentally get the battery connections reversed. Fuser-6 internal circuitry is rated at 25 Amps (30 Amp surge); no mean feat for a PCB design. To achieve SOTAbeams had to use a special PCB with double weight copper. They also use a clever design to further improve the current handling: ultra-wide copper tracks are used on both sides of the board. The boards are then roller tinned (on both sides) to reduce the resistance and handle heat even better. They use plated through holes, carefully located to ensure an even current distribution between each face of the board. Of course, Fuser-6 boards use genuine Anderson PCB contacts for lower contact resistance and improved reliability. NOTE: For best kit results use a soldering iron of at least 50 Watts. Additional flux is also helpful to ensure a good result. Additional details: * 25 Amps continuous, 30 Amps surge (adjacent connectors) * 1 input, 5 outputs * Power Bus resistance typically less than 1.80 milliohms end to end * Weight 135 g (less than 5 oz.) * W 68 x L 130 x H 40 mm (excluding connectors) 2.75 x 5 x 1.6 in. Whether you use one for your go kit, QRP setup or for use in the shack, these SOTAbeams Fuser 6 DC Distribution Boxes from DX Engineering are a handy DC power solution.

SOTAbeams LASERBEAM DSP Filter Modules
SOTAbeams LASERBEAM DSP Filter Modules work much better at reducing QRM than mechanical or analog filters. SOTAbeams applies special algorithm-based software to create well-defined passbands with steep contours. SOTAbeams offers their General Purpose, CW and SSB filter modules with switchable passbands. For example, the CW module (SBM-LB-MODULE-CW) may be used with either a 550 to 850 Hz passband, or a wider 300 to 1300 Hz passband. You choose the passband based on your own band conditions. Their SSB module (SBM-LB-MODULESSB) features passbands of either 300 to 2700 Hz or 300 to 2400 Hz. SOTAbeams designers have determined that these passbands work very well for SSB voice filtering. They offer their General Purpose filter module (SBM-LB-MODULE-GP) to accommodate both CW and SSB. These modules have selectable passbands of 550 to 850 Hz and also 300 to 2700 Hz. In this way you may limit CW or SSB QRM that is outside the selected audio passband. Be advised that these modules are NOT of the plug-in style. To use them takes some knowledge and soldering skill. You will also have to add an enclosure, if desired, as well as external parts not supplied with the PCBs. As designed, these modules will drive typical "low power" earbuds all by themselves. They will also drive audio amplifiers or amplified speakers. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Are you tired of battling the QRM?

SOTAbeams HF Antenna Trap Kits
SOTABEAM HF Antenna Trap Kits are a clever design with flexible mounting arrangements to make them easy to build and use. They are available in two power levels, 100 watt traps are listed here as SBM-HFAT-101 and 20 watt traps are SBM-HFAT-102. Each kit includes parts to build two (2) traps. Make your portable single band antenna into a multi-bander with our lightweight antenna traps. You decide on the frequency when you build them; recommended range 7 - 25 MHz. Alignment of each trap is accomplished easily with an antenna analyzer. For QRP super lightweight traps, see SOTAbeams PICO TRAPS for 10 Watts (DX Engineering part SBM-PITK-100). Included in each SOTABEAMS HF Antenna Trap kit: -2 x high quality trap PCBs with plated through holes -4 x 100pF 1kv capacitors (used in series or parallel to give 50pF, 100pF and 200pF options) -2 x mounting hardware for toroids -2 x toroids (T94-6 for 100W and a lighter T68-6 toroid for 20W) -Enameled copper wire to suit the power level Traps can be used in one of two ways. These SOTAbeams traps can be used either way, it's your choice: 1) By using a trap resonant on the higher frequency that you want your antenna to work on, traps work as an effective isolator. In this application, the trap needs to be resonated in the band. This configuration makes the antenna easy to adjust as the sections do not interact much. In this configuration, our traps show a loss of typically < 0.7 dB. 2) By using a trap resonant between the two bands that you want to use (typically 1 to 2 % percent below the band edge of the higher band), losses are reduced but adjusting the antenna is much more difficult as the two sections interact. In this configuration our traps show a loss of typically < 0.3dB. We recommend that you resonate your traps at the lowest edge of the band that the trap is to work at. So for a 20m-40m dipole, resonant your trap at 14.0 MHz. This tends to be a reasonable compromise between trap loss and ease of antenna adjustment. Instructions are linked in the Documents tab on the "More Detail" page. SOTAbeams HF Antenna Trap Kits Specifications: PCB Dimensions: 2.599 x 1.181 in. (66 x 30 mm) Insertion Loss: 0.3 – 0.75 dB depending upon resonant frequency Impedance at resonance: 20,000 Ohms, typical Weights: 20 W traps 0.4 oz. (10.6 g), 100 W traps 0.6 oz. (16 g)

Metal Oxide Varistor (MOV), Gas Discharge Tube (GDT), EMP Suppressor TVS Diodes, RF Bypass Capacitors and other wire lead components are easily connected between the control lines and ground. For effective protection wherever shunt devices are used, a low impedance ground is critical. The DXE-CLTB Control Line Terminal Board has four corner grounding screw holes for mounting on metal standoffs to a metal grounding panel inside an enclosure. DXE-CLTB-M Control Line Terminal Board includes a 10-pack of MOVs.

SOTAbeams BOXA-DUAL Amplifier Kits
SOTAbeams BOXA-DUAL Amplifier Kits are ideal for incorporating into your own designs. However, for additional flexibility these amplifier and enclosure kits have been designed to allow your LASERBEAM-DUAL filter module (not included) to be used with all your favorite radios. They have a professional look that will compliment your shack. BOXA-DUAL enclosures have laser-cut gold panels which screw into a rugged extruded aluminum case. BOXA-DUAL kits consist of a PCB that the filter module (not included) plugs into; together with an audio amplifier. The front panel features the CW Tuning LED (Sig) and Overload LED (Lvl) as well as a bandwidth switch (W/N) and volume control (Vol). The rear panel has 3.5 mm stereo jacks for audio in and out as well as a power jack for a DC supply (5-15 Volts). Power input is via a standard 2.1 mm power plug (supplied). The board will drive headphones or a small speaker. By changing two resistors, audio output can be increased up to 1.5 Watts which will drive a larger speaker. Because the filter module is a plug-in unit you can swap between different LASERBEAM-DUAL modules depending on your application. These kits use all through-hole components and are an easy build for a beginner. Build time is about 30 minutes. IMPORTANT NOTES: These kits: * Include amplifier and enclosure * Do not include a LASERBEAM-DUAL filter module * Are not suitable for LASERBEAM-VARI or LASERBEAM-817 filter modules Are you thinking about a LASERBEAM-DUAL filter module? If so, have a look at these SOTAbeams BOXA-DUAL Amplifier Kits from DX Engineering!
