Are you building your own antenna switching system? The BCD-10 Band Decoder/Antenna Selector is an important component in it. A board level product, the BCD-10 includes the switching logic and relay drivers to easily interface between your Yaesu® radio or computer and the antenna switches. The BCD-10 decodes the band select signals from the radio or computer to automatically select the proper antenna or band pass filter for the current band. The input signals are compatible with certain Yaesu® radios and logging programs such as TRLog and NA through the PC's printer port. The inputs are optically isolated to provide maximum isolation between your radio or computer and the antenna switching system. The outputs are grounding type open collector relay drivers. One output will be active, depending on the input signals. Outputs can be wired OR'd to select a single antenna for multiple bands. For example one relay may be used to select your tribander. With two jumpers on the BCD-10, the relay will be activated whenever your radio is set to 10, 15 or 20 meters. The BCD-10 covers all bands, 160-10 meters, including the WARC bands.
