The BCD-10 and BCD-14 Band Decoder / Antenna Selectors are designed for hams building their own custom automatic band switching systems. It uses the band data output of the Elecraft® K3, certain Yaesu® transceivers, or PC logging programs to automatically select the proper antenna or band pass filter when changing bands.
HSD-9 High Side Driver Board The HSD-9 High Side Driver board is the easy way to adapt a BCD-10 or other low side switching band decoder to a high side antenna or filter switch.
CW Beacon IDer The XT-4BEACON is the perfect start for your VHF/UHF beacon or other project requiring a CW IDer. Just plug in your keyer paddle and program your ID message. Its long, non-volatile memory space allows messages up to 90 seconds at 25 WPM.
