7 ADL Sentry User Guide
UHF radio within the United States without CSMA enabled. CSMA holds off the radio
transmission if the frequency is currently being used by a co-channel user. On occasion,
you may note that the radio broadcasts stop for short periods of time. Most often, this
is a case of co-channel interference and the radio is holding off broadcasts due to the
FCC-mandated CSMA.
Note – You should turn CSMA off when transmitting within the European Union.
GPS RTK equipment is designed to function with intermittent gaps in the data. Heavy
co-channel use may limit the ability of the radio to transmit the required information. In
areas of heavy co-channel usage, try changing channels to a less used frequency.
