Those frequencies are still in use and will be for a while. I had the same radio covering 30-50 mcs and that band is dying as more PD's move to higher ground as the skip will kill local comms. 150-174 is alive and well, although the channel spacing is changing from 15 khz separation to 12.5, then ultimately 6khz.
Your radio will still be able to tune those freq's albeit in metro areas splash could be a problem.
