What operating system are you using?  If it is Windows XP you can
use two LPT ports and some BCD to one of 10 decoders to control
the bandpass filters using Writelog's "Antenna Relay" interface.

With Vista/64 and Windows 7/64 there is no longer any support for
LPT (parallel) ports and you will need to use an external Band
Decoder to drive filter selection from the operating frequency of
each transceiver (or "Band Data" if your transceiver provides it).

What transceivers are you using?  Only Yaesu and the Elecraft K3
provide BCD "band data" while Icom provides a stepped DC voltage
that requires a different kind of decoder.

A "universal" solution is a band decoder like the microHAM Station
Master that provides independent antenna and BPF selection based
on the frequency information provided by the CAT/CI-V interface.
