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.
With excellent modulation characteristics including low noise, distortion, and broad passband, the GTX/GRX is a superior and low-maintenance STL.
Main Features:
• Compact, direct modulated low noise synthesized, oscillator, with 10 or 25 kHz programming step.
• External in-field programmability of frequency and power, without any special instrument over a broad range.
• Simple and modular internal construction facilities stage testing and servicing.
• Stable, high precision and temperature compensated crystal time-base.
• Balance/unbalanced audio, MPX and separate auxiliary SCA / RDS channel input, wide range level adjustable in small steps.
• Up to 6 separate LF input and output connectors plus RF/IF monitor for extended flexibility of use.
• Optional high-performance digital stereoencoder and decoder. This option may also be installed as an upgrade in the field.
• Narrow low-loss microwave input filter for high sensitivity and excellent performance in highly noisy RF environments.
• High efficiency, low-noise switch-mode power supply, with extended 90-260 VAC input range and battery backup input with recharging option.
• Complete digital control of all internal circuitry and extremely wide monitoring facilities. RS232 port for complete remote control.
