PROFESSIONAL HF BAND RRD «GALAKTIKA-M»

These receivers are purposed for operation in the composition of HF band radio centers or autonomously. They provide reception and demodulation of wide range of signals in frequency band of 1-30 МHz. Computer control (USB and RS-232 interfaces), Traditional LF and telegraph outputs, and digital outputs of I/ Q-samples provide wide range of functional capabilities


PRODUCT OVERVIEWThese receivers are purposed for operation in the compositionof HF band radio centers or autonomously. They provide receptionand demodulation of wide range of signals in frequency bandof 1-30 МHz. Computer control (USB and RS-232 interfaces),TraditionalLF and telegraph outputs, and digital outputs ofI/Q-samples provide wide range of functional capabilities.
