ColibriDDC

659.00 

The new ColibriDDC is a small sized SDR receiver covering 10 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.

Software
The ExpertSDR2 software package is used to control the ColibriDDC receiver. The software provides two independent receiving channels with up to 312 kHz bandwidth. It comes with a preloaded database of broadcast stations which together with the ability to record entire broadcast bands for later playback makes it an excellent choice for broadcast DXers. ExpertSDR2 runs under Windows XP/7/8 x32 or x64 and Linux Ubuntu x64. Minimum hardware requirement is Intel Core2Duo, video card supporting OpenGL 1.5 and RAM 256 or more RAM.
