I am an absolute novice and own a BCD436HP. I have been using Sentinel via VirtualBox on my MacBook to program it. That is a technical issue on it's own that is driving me crazy. Anyway, I have somewhat gotten the hang of programming the BCD436HP through Sentinel. So, I have just recently bought a SDS100 and am looking forward to receiving it for its simulcasting capabilites over the 436 as I live in a large metropolitan area. My question is when I plug the SDS into my computer and target the SDS through Sentinel can I use the programming I made for the 436, i.e. Favorites, and just write that to the SDS? Or, do I need to program the SDS as an absolute separate entity from the 436? Also, if I am able to use the programming for the favorites from the 436 to copy to the SDS will I be able to capture simulcasts? I am not sure how simulcasting works. Is it separate programming? Thanks, and remember I am an amateur.
