Indeed, the inexpensive DVB-T dongles are showing up in many places including as David noted, decoding GPS.
For some details: This gets you to the start of their web site: http://gnss-sdr.org/ This is an interesting document they have published on their project: http://www.cttc.es/wp-content/uploads/2013/09/Turning_TV_into_GNSS_Rx1.pdf The AMSAT Fun Cube Dongle is a very capable and interesting device. Interestingly it uses the same Elonics E4000 front end chip that many of the inexpensive DVB-T devices do. Apparently Elonics is no longer in business and the inexpensive DVB-T devices using this chip are becoming less common. The DVB-T devises using the R820T chip are becoming the preferable versions when those with the E4000 cannot be found. I wonder if the Fun Cube Dongle will be likewise changed (perhaps it already has).

Many "scanners" now go to that frequency e.g AOR AR-8600. (100kHz to 2GHz ) They are hardly state-of-the-art receivers but should be capable of detecting jammers driving past. However a new unit is quite pricey $1000 equivalent in the UK as little as $300 for a used version. Also the AMSAT FCD Pro+ USB SDR at $200 and free software. Alan G3NYK ========================= Or even the DVB-T dongles at just a few pounds (and with a wider bandwidth), covers up to around 1.7 GHz, I have red.
