OK first off Thanks everyone for your help.  Trunking is a fairly new concept 
here so bare with me as I ask a few more questions.  First off, CSI Seems to 
have some nice controllers however there could be an issue here with radios 
being cloned and then put onto my ltr without my knowledge.  Is there a type of 
controller where I can somehow track this?  2nd question, I know motorola uses 
up one repeater for a "Control Channel" which can not be used for voice.  From 
what I understand, LTR does not do this correct?  I will be putting farmers and 
bussiness onto this system and I want to make it expandable so that if need be 
it wont be a huge deal to add 1 or 2 more repeaters when the time comes.  Also, 
does anyone have any suggestions regarding high gain antenna's, multicouplers, 
etc?  Thanks for all your help.

Depending on the radio and ltr trunking controller, you can can make 
groups and have id numbers within the group and decode only the desired 
group. With Kenwood Radios and CSI trunking controllers it's pretty 
easy and straight forward.

Nah.... even a 2 channel LTR system is very practical vs days of 
old when community ctcss/dcs format was king. Both channels are 
working and the customers don't have to hear the co channel or 
co system users. 

If you ever had two mule headed customers fighting on a community 
repeater... moving them to LTR made everything spring day fresh 
(although their vehicles often remained rather stinky). 

More channels is butta' but 2 LTR Channels is a quite usable system.

cheers,
