MULTICHANNEL RRD OF HF BAND «GALAKTIKA-4K»

This device is to be operated in the composition of HF radiocenters, it provides signal reception by four independent channels in the 1-30 MHz frequency band and also provides signal transmission in analogue or digital (I/Q-samples) form to the consumer. Computer control (USB interface), traditional LF outputs and digital outputs of I/Q-samples provide connection of consumer equipment on subcarrier frequency.
