duh-because when repeaters were first authorized for 2M, they were only allowed from 146 to 148. 144.5-145.5 didn't come into existence until the 80's. No-2M is too populated to do any changes. Not gonna happen until they just flat stop making FM gear. Not in my life time, not in your kids lifetimes, probably not in your grandkids lifetimes either. Same with the 150-174 LMR band...WAAAAAY to much gear out there to try to standardize input/output. Look at the bright side-at least the ham band HAS a standard. There is none in the LMR segment.
