mixers. The state of the CHANNEL logic signal from the FPGA causes the local oscillator to output the appropriate
frequency for either Channel A or Channel B operation.
3.2 RF CHARACTERISTICS
In rural areas, the Model 1225 provides line-of-site communication range with a practical limit of
approximately 3 miles over normal terrain. Suburban communication range is affected by reflections and fading with a 0.5
mile radius being typical. In metropolitan areas, communication ranges are dependent on the site characteristics such as
building density and RF environment. Operating ranges of approximately 1 block radius are practical.
