Ameritron makes an RCS12 control head that I use here. I have about a dozen of them in use.
It not only is programmable as to the allowed output ports for a radio's band data input, it also works as an antenna switch controller and will lock out the wrong antennas on the wrong bands. It prevents hot switching antenna relays by locking out any changes while transmitting. Band decoder and antenna controller with amplifier lockout all in one box. :-) http://www.ameritron.com/man/pdf/RCS-12.pdf 73 Tom > As suggested by someone else, W9XT BCD-10 is a very good, simple > decoder for use with the K3 if you are only controlling a single > device (e.g. filter switch).
