Automatic Station Identification
For operation in the United States, the FCC requires that radio
transmitters used for GPS RTK applications periodically
broadcast a station identifier. The station identifier is the call
sign assigned to you on the station license.
The PDL supports the broadcast of station identification in a
manner that meets the requirements of the FCC. Upon receipt
of equipment, program your FCC callsign into the configuration
of your PDL using PDLCONF software. This is only required for
transmitters.

Warning: Failure to transmit your station identification
is in violation of FCC regulations. Use PDLCONF
software to enter your FCC callsign.
Carrier Sense Multiple Access (CSMA)
CSMA is a technology implemented in the PDL Base to meet
FCC transmitter requirements. 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 PDL Base is holding off
broadcasts due to the FCC mandated CSMA.
GPS RTK equipment is designed to function with intermittent
gaps in the data. Heavy co-channel use may limit the ability of
the PDL Base to transmit the required information. In areas of
heavy co-channel usage, try changing channels to a less used
frequency.
