The new ColibriDDC is a small sized SDR receiver covering 9 kHz to 55 MHz and with external filters capable to receive frequencies up to 800 MHz. Direct digital signal sampling using a high speed digital to analog converter results in very high performance from a light and small package. The receiver is controlled via LAN opening many possibilities like remote control or control of several receivers from one PC. With the optional E-coder hardware controller it can serve as a second RX in a contest or DXing setup.
