What is the difference between the RTL2832U FC0013B 22 - 1100 MHz and RTL2832U R820T 24 - 1766 Mhz dongle?
It is only the Frequency range and the antenna conector that is diffrent.
The DVB-T dongles is based on the Realtek RTL2832U and can be used as a cheap SDR, since the chip allows transferring the raw I/Q samples to the host, which is officially used for DAB/DAB+/FM demodulation. The possibility of this has been discovered by Eric Fry (History and Discovery of RTLSDR). (With the nessary software and antenna you could listen to the following frequensies 48.25-863.25 Mhz.
Officially the RTL dongle dokumentation only specify the frequency range "48.25-863.25 Mhz" but the one's I have tested do work from about 24MHz to 1766MHz with a dead spot just above 1.2Ghz
To see this RTL dongle in action go to my webSDR at http://zr6aic.giga.co.za:8901 the 2m band is using RTL dongle.
It has an MCX antenna connector, which is not really popular so you will need adapter if you want to connect external antenna.
