As I said in my intitial response, I use ARC 300 from Butel Software. Here is how I have programmed the various banks in their program:
Bank 0--System 1
Bank 1--System 2
Bank 3-- DB
Bank 4--System 1
Bank 5-- System 2
Bank 6--DB
There are a total of 315 talkgroups. I have chosen 300 of them and broken them into two groups.
In bank 0 I selected as many talkgroups allowed. I put those same talkgroups in banks 1 and 2.
In bank 3 I selected the remaining talkgroups. I put those same talkgroups in banks 4 and 5.
In otherwords if you split the talkgroups into two groups, let's call them A and B, I put group A in banks 0, 1, and 2. I put group B in banks 3, 4, and 5.
Make sure the setting is set for EDACS and I use a closed bank setting.
In banks 6, 7, 8 and 9 I put other frequencies of interest to me such as air, local, etc.
I'm not sure this is the best way to do it or even the right way to do it. Maybe others have ideas that will help us both.
