What is the difference between the RTL dongles

  1. RTL2832U FC0013B 22 - 1100 MHz (Frequency and antenna conector)
  2. RTL2832U R820T 24 - 1766​ Mhz (frequency and antenna connector)
  3. This RTL2832U R820T2 25 - 1766​ Mhz (frequency antenna connector better noise floor about 6dB lower, slightly better sensitivity, Sample Rate up to 10MHz (But USB will limit you throwput to about 3.2Mhz)
    The T2 has different intermediate frequency filters allowing for wider IF bandwidths and apparently slightly better sensitivity (a few dB lower noise floor?). For rtlsdr dongles this difference in IF filter bandwidth usually doesn't matter much since all of them are larger than the RTL2832U's debug/SDR mode bandwidth of ~3 MHz. But there are certain situations where a larger tuner bandwidth is advantageous: such as when using Jowett's HF tuning mod.

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 documentation 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

If you want to no more how to configer and install the RTL dongle read more on the blog http://zr6aic.blogspot.com/search/label/RTL2832U and http://zr6aic.blogspot.com/search/label/rtl_tcp

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 to external antenna.

Windows SDR# software is available here
