RECEIVE AND TRANSMIT

Talk Range
The IC-40Jr is designed to maximize performance and improve
transmission range in the field. However, the single most impor-
tant factor in transmit range is your surrounding environment.
These radios are "line of sight" radios and as such, transmission
range is influenced by the degree to which you can "see" the
other communicating party. Large concrete structures and heavy
foliage or transmission from inside a building or vehicle will re-
duce your talk range.
• Optimal range : wide, open areas free of obstructions.
• Medium range : large buildings or trees blocking your line of
sight.
• Minimum range : mountainous areas or areas of heavy foliage.
