I understand between my repeaters and other locals that I also identify because of coexistence with my digi's. They are a mix of VHF & UHF FM, P25 VHF and VHF & UHF Fusion. Just up the road is DStar. Making these more visible to traveler would be a plus. Hopefully in future radios the standard can be expanded on to accommodate these new formats in an auto tune function on a radio. 

I will make the adjustment to the comments on the digi's. 
I would like to see this go forward.
