i – The 60-meter band cannot be selected with this method.
BCD input – A 4-bit BCD signal (5 to 15-volt DC) selects a band and its filter. The pins are opto-isolated. Pin 15 is
the signal ground.
The BCD inputs are designed for connection directly to a band decoder output provided by radios such as Yaesu
and Elecraft.
