Band Decoders and Antenna Relay Boards
Unified Microsystems Band Decoder/Antenna Selector Modules
Unified Microsystems Band Decoder/Antenna Selector Modules are important components if you are building your own automatic antenna switching system. These modules include the switching logic and relay drivers to easily interface between your Elecraft K3, Yaesu radio or computer, and the antenna switches. Use the BCD-14 to decode band switching for up to 14 relays. The BCD-14 modules decode the band select signals from your radio or computer to automatically select the proper antenna or band pass filter for your chosen band of operation. The module's inputs are optically isolated to provide maximum isolation between your radio or computer and the antenna switching system. Module outputs are grounding-type open-collector relay drivers. If the antenna or filter switch you wish to control requires high-side drivers, add the optional HSD-9 module. One output per band will be active, depending on the input signals. However, outputs may be wired to select a single antenna for multiple bands. For example, one relay may be used to select your tri-bander. With two jumpers installed on the BCD-14, that relay will be activated whenever your radio is set to any one of that antenna's three bands. The BCD-14 covers all bands, 160-10 meters, including the WARC bands plus 6 meters, 2 meters, and 440 MHz. The BCD-14 boards have corner mounting holes, but hardware, enclosures and antenna relays are user supplied. Why risk transmitting on the wrong antenna or put yourself in the position to require manual selection at all? Use this economical Unified Microsystems Band Decoder/Antenna Selector Module from DX Engineering, to build your automated antenna selector system!

DX Engineering MX2X8 Interface Unit
The DX Engineering MX2X8 Interface Unit is a specialized relay device used only for the interconnections between the DXE-RR2X8 Two-Radio Eight Port Remote Antennas Switch and two DXE-CC-8A Control Consoles. This Interface Unit allows failsafe selection and operation with two radios, each to one of eight antennas, preventing selection of the same antenna. This unit is a component of the packaged 2 x 8 Remote Antenna Smart Two Radio Switch System. It does not serve any other purpose and should not be ordered separately.

Unified Microsystems High-Side Driver Modules
Unified Microsystems High-Side Driver Modules, (HSD-9), are the easy way to adapt a BCD-10, BCD-14, or other low-side band switching decoder to a high-side antenna or filter switch. They provide nine channels of high-side relay control when used with low-side drivers. Antenna switches are always either high-side or low-side switched. There are advantages to each, but it's a pain if your decoder and switch are different types. These HSD-9s are a convenient way to convert the BCD series or other decoders to high-side switching. Simply place an HSD-9 between the BCD-10 and your switch. Specifications: * Nine channels of control when used with BCD-10 selector modules * Board dimensions: 2.4 in. by 1.9 in. * Maximum voltage: 24V DC * Maximum current: 1A Note: Use of an HSD-9 REQUIRES a companion BCD-10 or BCD-14 Band Decoder/Antenna Selector Module or other low-side band-switching decoder. These high-side driver modules are an important component if you are you building your own automatic antenna switching system and employing switches requiring high-side drive. Use one of these Unified Microsystems High-Side Driver Modules, now available from DX Engineering, to convert your relay driver!

VE2DX Electronics Band Decoders
VE2DX Electronics Band Decoders, available here in limited final production quantities, with three versions. They can be set up to control remote relay antenna switches and band pass filters by interfacing to a wide range of transceivers via direct connection, Bluetooth, USBoIP via WiFi and/or direct WiFi/LAN connections, when available. They interface to transceivers to decode up to twelve user defined frequency bands for the control of either eight or sixteen outputs and may be updated for band changes or new band arrival. VEX-BD1-BT Band Decoders interface with one radio and provide one set of eight outputs to automatically control a single remote multiport antenna switch OR a band pass filter (BPF). VEXD1-BTPlus Band Decoders interface a single radio to two sets of eight outputs to automatically control a remote antenna switch AND a Band Pass Filter. IBD2-BT Band Decoder is the top-of-the-line unit that can interface with a dual receiver transceiver and offers two sets of eight outputs to either automatically control two remote antenna switches, or two Band Pass Filters, or one of each. VE2DX Electronics Band Decoders are powered via a USB-C port to a Windows PC. Internal jumpers are user set to control output functions and configure support transceivers from FlexRadio, ICOM, Kenwood and Yaesu. Included with each VE2DX Electronics Band Decoders all of the following advanced features: • VE2DX TrueTTL • VE2DX TrueCAT • VE2DX TrueCIV • VE2DX Blind Operator Assistance (BOA) • VE2DX Software Defined Interlock (SDI) • RFI filtration • Heavy shielding • Signal processing • Automatic signal leveling • External Voltage Switching • CAT/CIV support • Automatic RS232c/TTL support • Wi-Fi • USB-C • Internal/External Voltage Switching • GND Switching • Status/Error messages in CW or Decimal • Mismatched Radio manufacturers • Mismatched remote switches • Mismatched band/output configurations • Blocked outputs on error • Twelve band frequency definitions per output sets • Eight output sets with support of multiple band definitions • Automatic SWR detection with assigned output VE2DX Band Decoders come with multiple LEDs for fast status checks of the Band Decoder: • Power (RED) • DATA (Cat/CIV, RED) • Automatic (RED) • Selected Radio (Green) • Error (RED) • Outputs (Yellow) • SDI - Software Defined Interlock - (RED on the IBD2-BT only)
