Mine were 10 mhz based and I converted them to 12.8 mhz reference... In the tait software I used there was a provision to specify a lot of stuff including generating a list of channels based on a step size from an origin up to x channels. I need to dig out my software asn such. I also PDF'd the manuals for the TX and RX. If I can find those I can forward them. I am not finding them on my main desktop, I think they are on my ham computer in the basement. I will look later...
