To hear KCPD Icalls, all you have to do is enter the individual unit numbers. For example: on my BC296D, I have the Icalls programmed according to zone. So, if I wanted to monitor all of the 120 sector officers in Center Zone, I would program i000120 (for officer #120), i000121 (for officer #121), i000122 (for officer #122), and so forth. I have no clue if KCFD has or even uses the Icall feature.
