Overview
Marti GTX / GRX Series STL Systems
The GTX / GRX is a modern direct-synthesis, frequency-agile Studio to Transmitter Link (STL) with a wide frequency range spanning from VHF to SHF. Both transmitter and receiver offer full digital readout with a simple and intuitive front panel jog wheel, coupled with extensive RS232-based programmability and monitoring. A web-based UI is also available.
All new Marti GTX/GRX series of Studio to Transmitter links which offer the robustness of the Marti line, plus many advancements in performance, ease of use, and maintainability. The Marti GTX/GRX are available in most standard STL frequency bands from 215 MHz to 2.6 GHz, and are frequency agile within each band, eliminating hard to find crystals, and in power levels up to 15 watts.
