Transmission Rules and Regulations
Licensing requirements
It is the responsibility of the owner to comply with applicable rules and regulations
concerning the operation of a radio transmitter. In the United States, the FCC regulates
the licensing of this equipment.
The TDL 450L and TDL 450H transceivers use extended frequencies and may contain
functions that are not operational in the United States and its territories. Users should
check with the radio authority of the country of operation for any restrictions that might
apply.
Application for a license is made by submitting FCC Form 600 along with evidence of
frequency coordination (if required) and applicable fees. Similar licensing requirements
exist worldwide. Penalties for broadcasting without a license can be severe, and may
include the confiscation of your radio.
For more information, contact our customer service department.
WARNING – Always obey local licensing requirements and restrictions. It is illegal to
transmit in the United States while CSMA is turned off. CSMA is not required within the
European Union and should be turned off.
Equipment compliances
The radios have been tested and found to comply with Parts 15 and 90 of Title 47 of the
Code of Federal Regulations. They have also been tested and found compliant for type
certification and approval in many other countries worldwide.
For more information concerning our worldwide compliances, contact customer support.
5 TDL 450L/TDL 450H User Guide
Being part of the RF community
Operation of a licensed radio product makes you a member of the RF community.
Be aware that virtually all frequencies licensed are provided on a shared basis with
other users. Each frequency dedicated specifically to RTK surveying activities has
certain restrictions and limitations. For complete information, refer to the appropriate
documentation from the licensing agency in your country of operation, e.g., Part 90, Title
47, of the Code of Federal Regulations.
Most frequencies sharing data transmissions and voice transmissions give priority to
voice users. Be mindful of the persistent nature of a GPS RTK data transmission and
always limit your RF transmission output power when performing close-in survey
situations to avoid interference with co-channel users. Trimble recommends using the
low RF power setting for construction site and other line-of-site surveys with baselines
less than two miles (depending on terrain).
WARNING – If you are in conflict with a co-channel user, select another frequency to avoid
formal actions by government agencies. In most cases, you are required to vacate a frequency
upon complaint by a shared channel voice user.
Most survey operations are itinerant in that the system is moved on a frequent basis.
For fixed system installations, you should not use frequencies set aside for itinerant
operations, but should coordinate a frequency based on the fixed area operation.
Regulations differ from country to country, please be aware of the local regulations before
using radio equipment.
Automatic station identification
For operation in the United States, the FCC requires that radio transmitters broadcast a
station identifier every 15 minutes. The station identifier is the call sign assigned to you
on the station license.
The radios support the broadcast of station identification in a manner that meets the
requirements of the FCC. Upon receipt of equipment, use the TDLCONF software to
program your FCC call sign into the configuration of the radio. This is only required for
transmitters.
The call sign is transmitted every 15 minutes in Morse code. It is not included in any
data packet and so is not processed by the receiving radio. However, data transmission is
interrupted for a few seconds while the call sign is being transmitted. If you leave the Call
sign field blank (on the TDLCONF Identification screen), the radio programmed with this
configuration file will not transmit any call sign.
WARNING – Failure to transmit your station identification is in violation of FCC regulations.
If you are operating outside the United States, check with the local authorities if you need to
transmit a call sign.
Carrier Sense Multiple Access (CSMA)
CSMA is a technology implemented in the radios to meet the United States Federal
Communication Commission (FCC) transmitter requirements. It is illegal to transmit on
any UHF radio within the United States without CSMA enabled. CSMA holds off the radio
6 TDL 450L/TDL 450H User Guide
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 cochannel 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.
