XTS1500 MDC Call List Question. I am new to the Astro series programming but have been doing Waris for years and have some experience with TRBO, so this is a little different for me. I know that each MDC call list is limited to 50 MDC aliases, which isn’t a huge deal because we only have about 50 radios at my department anyway, we just wouldn’t be able to have the other departments in my Township loaded in. I set up a second call list for our EMS channel with their ID’s on their channel, but I notice when they switch over to ours, they still decode as well (which is good). Would I be correct in assuming that I could program other stations into different call lists and they would display radio wide, or am I incorrect? What is the limit for how many call lists you can have?
