The new fascination here is Software Defined Radio, or SDR. I've purchased a transceiver (called the BladeRF) from a company called Nuand. They had a Kickstarter last spring and actually delivered on their promise (Kickstarter projects are not guaranteed).

The board is much more capable than the DVB-T dongles that everyone is playing with, but of course, costs more ($420).

Because it can process much larger bandwidths (up to 40 MHz), it can be used as an ATSC spectrum analyzer. Here's a screenshot of KICU-DT on channel 36 here in Silicon Valley. The antenna was just a rubber duck laying on the workbench.


The program is called gqrx and it's running on Linux (Ubuntu 13.04). It uses GNU Radio and osmocom as libraries. All open source software.

There's just been a very popular Kickstarter for another SDR called HackRF.

It has better frequency coverage that the BladeRF, but not as much bandwidth or bits per sample.
