It would be helpful if we knew which system you were trying to program...however, from the way you asked the question, I kinda suspect that you might be having some problems understanding trunking. We have a wiki article on
Trunking that should get you on the road to understanding. Read the basics and FAQs first. (anything in blue is a link).
Once we know what system you are trying to program there are several folks here that can help. Software wise, ARC246 (for your BC246) and ARC898 (for your 898) from
BuTel are pretty much the champs, but don't overlook
Scan Control (which will work with both scanners) as well.
