Contact BSW for your pricing and shipping!

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.
