GENERAL DESCRIPTION
This transceiver is an advanced AM/FM
2-way radio designed primarily for mobile
operation.
It employs the very latest
technology to provide 80 channels of
operation by means of digital frequency
synthesis with Phase Lock Loop (PLL)
circuitry.
The use of PLL circuitry as
sures a précisé on-frequency operation on
every channel in both AM and FM modes
that is unmatched by conventional crystal
frequency synthesis.
This transceiver also includes many fea-
tures which will provide greater operating
convenience and assure optimum com
munications under a wide range of
conditions. Other features are:
• 80 channels operation
• AM — FM mode switch for easy sélec
tion of operating mode.
• Illuminated meter indicates "S" units
