 Police in the U.S. also used frequencies around 2Mc (as we called it
 in the old days).  My city police department shared 2,490Kcs with at
 least 12 agencies, including the county sheriff, the fire department,
 the state highway patrol, the county coroner, and several other city
 police departments.  Before we had private line decoding, departments
 from the Mississippi River were heard all the way west into San Diego.
