Yikes! So, it's safe to say that it's not only your desire to be able to listen to anything, but to listen to it all at the same time?

Around here, just about everything is trunked -- every 'burb has it's own, Denver too. I think DIA even runs facilities on a trunked system. One statewide APCO system. Here in the NW burbs, Arvada and Westminster share a trunked system (just different talk groups) on Eldorado Mountain. I think the hams were up there first.
