SDR with $20 USB Dongle

You can now have a SDR (Software Defined Radio) for $20!  The dongle is receive only, but it can handle from 64 MHz to 1700 MHz.  It works in both Windows and Linux.

The dongle is actually a USB DVB-T TV receiver that uses the RTL2832 chipset along with a E4000/FC0012/FC0013 tuner.  The DVB-T is not supported in the US, but there are plenty on eBay and elsewhere.  Here is a list of supported devices.

There is a pretty active group over at Reddit that has been helping each other out.

I have successfully run it under Linux with GNU Radio and in Windows with HDSDR using Balint256 drivers.

You can also follow our findings with SDR via the Wiki.
