1722 and 1730kHz are still available for use by police departments
(see http://www.hallikainen.com/FccRules/2007/90/20/) . A search of
the FCC Universal Licensing System does not turn up any licensees
using either of these frequencies. There are a lot of licensees in the
1700 to 1800 kHz region. Some of these are from the "public safety
pool," but are Travelers Information Service stations instead of
police dispatching.

Back in the late 1950s, I had an "American Five" vacuum tube radio that
had the police band marked above the AM broadcast band. In the San
Francisco East Bay area, I could hear Los Angeles police dispatch.
