I guess I'll have to pull the 567 ctcss decoder I built way back when... even though it still works just fine... I copied a Yaesu 567 CTCSS Encoder/Decoder circuit and it works well to this day. Still have the diagram around here somewhere but you can also reference the TD-3 circuit I provided a link to in an earlier post. s.
