DVB T

The DVB T USB dongle is intended for watching over the air TV broadcast. You can get one of these for $10 to $20. I am using it will gqrx under linux. It makes a usable spectrum analyzer.

It just needed some modifications to improve its usefulness and performance.

It just needs a more common RF connector. Like an SMA connector.

It also gets pretty hot after it has been running for a little while so I added a heat sink and a new case. The heat sink helps but it does get to 45C. Thanks to my 3D printer a new case with the heat sink was no problem.
