INTRODUCTION
Advanced state-of-the-art technology is used in the design and manufacturing of the VHF and UHF
scanning hand-helds. The Phase Lock Loop (PLL) synthesizer provides more flexibility and capability in a
radio than ever before offered. The VHF and UHF scanning hand-helds has 4 or 16 channel capability,
depending on which model is chosen. It offers CTCSS, DCS, scanning, priority channel, and many other
functions. All these functions are controlled by the micro controller. The micro controller reads specific
channel information from an Electronically Erasable Read Only Memory (EEPROM).
