The user interface
is a multi-function LCD display that provides a variety of windows
for setup and operation. The main window provides full system operating
information including transmitter and receiver battery levels, RF
and audio levels and diversity antenna state. Other windows provide
frequency and level settings and a unique spectrum analyzer.
The spectrum analyzer will automatically tune the receiver across
its entire bandwidth and display the results in a scrollable window
to identify signals that are present and clear operating frequencies.
Microprocessor
control is at the heart of the UCR301. Internal functions such as
diversity antenna phase and squelch activity are controlled by internal
firmware that analyzes a variety of conditions to optimize performance.
