I think there are actually two versions of the Vastelec controller. The single board version is what I have and what they are selling over on DIYC. I know that Kevin over at DIYC got the RDS working on the two board version of the transmitter. I think however, that there was a post last year that said somebody got it working on the single board version. At least they showed how to connect it.
The boards from last year look identical to the ones from this year. Since I have an extra I figured I'd just try it and see. If it doesn't work like they now say it shouldn't, no big deal.
