Overall, very nicely written up. There are some glaring errors on that page, though. For example: "With the BCD996P2, you can choose to put both counties' trunked services into one System" (to scan multiple trunk systems).
Doing that will result in NOT SCANNING one of the two systems, as only one control channel will be evaluated (the first one the scanner hears).
Why someone would ever try to program two systems as one is beyond reason. Just program them as they are - two separate systems. Then each will be scanned.
