Never thought of it to use it simultaneously. > This would spare you a lot of correlation. Yes, that is exactly how I got the idea. So I intend to use RDS. I already have an RDS decoder in place. You still need a correlation for the phase/time relationship but you don't have to correlate every frequency to determine if it is a "mirror" of your current station.
