Details

Topcon TRL-35 Radio

The TRL-35 is a transmit/receive/repeating digital UHF modem. It is a 35W high powered base radio that uses the same DSP technology as is used in the GR-3 Digital UHF Receiver.


The TRL-35 Radio can be used to enhance the following survey related systems:

  • As a high power transmitter/receiver external UHF radio for any base system
  • As a high power repeater (not in PDL protocol currently)

Obstructions such as buildings, terrain, trees, and so forth greatly affect the usability and range of any radio system. However, the TRL-35 as a high powered transmitter/repeater provides an increase in the operational range and effectivity of the system in unfavorable environments.


The TRL-35 is compatible with:

  • GR-3 Digital UHF radio
  • Existing Pacific Crest Radios (Currently only PDL radios using GMSK modulation)
  • Trimble Radios using Trimtalk 450s (currently only Trimble radios using GMSK modulation)

Simple features and configurations allow the TRL-35 to be adaptable to most situations, and make it easy to use.
