This scanner was found in almost all CHP cars in the 80's so they could monitor towns and cities they were in.
It has the best audio of any scanner I've ever had, and is built like a tank.
With an unlock password it's 800MHZ range could be unlocked up to 956mhz.
It also received the AM .aircraft band.
Built incredibly well, and has professional police/fire look to it.
I've uploaded doc, unlock info, and programming software
