Huh? Trunking only means that several repeaters are controlled and coordinated as to use, and there are many repeaters that operate with much less than a 1 MHz separation. Yes, the equipment is larger, but it can be and is done all the time. So, it is technically possible to do it there. Now, legal issues are another matter...
I didn't address the original post since I knew there were many different bands for CB in different parts of the world. There have been four in the USA alone (and still are two - Class D on 27 MHz and Class A on 462/467 MHz... AKA GMRS). I think the Class C (remote control) band still exists, too. That uses the 'unused' CB channels on 27 MHz. To complete the info, Class B was a 465 MHz AM single channel band. Now, trunking or repeaters there would be a little 'difficult'. ;-> Joe M.
