If anybody out there has a Miller wireless pedal and can get me a photo of the plate with the FCC ID on it, I can look up what frequency it uses, just for fun. Honestly, the frequency alone won't tell us much, because the modulation and encoding techniques are really where the magic happens--unless they're using pure analog modulation, but I would bet not. If you knew the frequency AND you had a signal analyzer, you could pretty quickly figure out what encoding/modulation they're using. Realistically, this stuff is probably all defined in patents anyway, so if you wanted to reverse-engineer it for personal use, that would be where to start.
EDIT: Never mind. I found the FCC ID on the web, although I'm having trouble looking it up in the database.
