Small-size ColibriDDC receiver is intended to receive signals in HF frequency bands from 0.09 to 55 MHz, and also with the additional external filters to receive frequencies up to 800 MHz and operater with a PC. Receiver was designed in accordance with the principle of direct digital signal sampling by high speed analog-digital converter. Such architecture allows to suppress noise of analog stages and makes the air sound natural and transparent. Local network interface allows remote operation over a network and also allows to connect simultaneously several receivers to one PC.

Note! The receiver does not contain band pass filters and may be overloaded by strong near-by signals.
