Thanks Dave,
I will browse your blog, I hope I find the firmware (either .asm or .hex) for
the PIC there.

All:
Here is a bpf board I am designing. It uses a small PIC to decode
either 4 bit binary or I2C to control the selection relays for the band
pass filters.

Hello Dan,
I think better you upload the implementation of the method bellow in the
applicable schematic especially for us less experience in such topic.

It might be better to send the lines to another processor. It would be nice
from a current consumption point of view to use latching relays, which means
the set/reset pulses would work better under a second processor control. Some
of the PIC chips are really cheap and the processor would be doing almost
nothing.

Use 74HC138N 3 line to 8 decoder a transistorto drive the relays ....
138 is active low outputs, 238 is active high outputs so you can
have anything you want
