At a minimum, to get a trunked system up and running, you will need the system frequency list, home channel, area code, and ID number.
Frequency list - an LTR system can have up to 20 repeaters to choose from. You need the freq list for your system and enter them in the correct slot, 1 to 20. It may have only 2 or 3, or maybe 15 or all 20, but they have to be in the right order and right slot (LCN).
Your system admin will assign a home channel (1 to 20) and ID. Home channel must be correct as this is the first repeater your radio will try to connect to. Only if this repeater is busy will the system issue a trunk off to your radio if you try to transmit. Next is ID (001 to 255). Only valid ID's are programmed into the system. Think of it like PL's. Every user gets a different ID. Don't pay for your airtime? Your ID is disabled. Normally encode and decode IDs are the same, although split IDs could be used.
Last is the area code. Usually it is set to 0. If systems overlap, one system may specify area code 1. This is used to prevent false decodes from the overlap. Use what is assigned.
In KPG89D, set a zone as trunking, go there and enter IDs (plus other info), then click "REPEATER" at bottom and fill in other info.
If you're still stuck, cry uncle...
