A scanner is, generally speaking, a VHF/UHF receiver that is optimized for
quickly scanning preset memories, usually using narrow FM mode or AM mode
for air band. The AR8200 is really more of a communications receiver, which
is a more flexible unit capable of receiving a wider range of frequencies
and modes (such as CW and SSB) with finer control over the tuning step size
and other parameters. The AR8200 is also capable of scanning preset
memories, of course. Traditionally, comms receivers are more expensive, but
now with the digital scanners available, that's not always true.

And the AR8200 doesn't do digital and it doesn't track trunked
systems.
