I am attached to multiple professional radio companies here in Toledo, Ohio. I mostly just know the guys, and they are all hams also. I hang out with a few of them a whole lot. I know that any pro radio company can get you a few portables and rent you time on an established repeater in town somewhere. You can also pick between conventional and multiple types of trunking systems. I have access on channels and repeaters here in the conventional, LTR trunk, 800 MZ type 2i trunk, and APCO 25 trunk systems. If the trunk systems have enough voice channels to keep you from getting busy outs then they can be a good, kinda private, system to rent time on. Just some thoughts of mine. Jerry
