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!

Unified Microsystems ML-6 Replacement LED Lamp boards
Unified Microsystems ML-6 Replacement LED Lamp boards use reliable LEDs to replace the hard-to-find incandescent lamp used to illuminate the meter in Hy-gain™ and CDE Ham-M type control boxes. Six white LEDs provide longer life, even illumination and adjustable brightness to achieve the perfect lighting level for your shack. The ML-6 is easy to install. Peel the backing paper off the Velcro™ tape and press the circuit board on the top of the meter, solder the two wires to the old lamp holder, adjust the brightness and you are done!
