glad you like ;)

DCO->AM might work... i'll have to look into that.

DCO->FM(DCO) won't work. the DCOs are digital, so you can't just run a 
wire between DCOs and get modulation. if you're new to this list, you may 
not have heard about the new OS for the 800, and you might ask about doing 
DCO cross modulation in software, but i'm pretty sure the CPU and/or 
hardware won't work that way.
