Realistic Patrolman PRO-3 Monitor Receiver
A Realistic Patrolman PRO 3 Monitor from the early 1970s.
Radio Shack promoted this would be "the only monitor receiver you'll ever need" - little did they know the changes that would come. In the mid 1970s the UHF band was expanded to 512 MHz. In the 1980s came the opening of the 800MHz band and trunked radio systems, and today the 700MHz band is also used for public safety - not to mention today's digital trunking and modulation.
