Well I'm not particularly needing any one code at the moment, just trying to figure out how exactly to figure out the hex codes.
Thanks for the great tutorial on the rest. It makes it easy to change the config when I want instead of having to call someone with a programmer. Now if I can find a connector that goes into the socket on top of the display board I could just wire up a connection to the ICSP connector on my board and make it easier for the frequencies. This information should be put on the repeater-builder web site if it's not already. I couldn't find it, but maybe I didn't look close enough.
