The Hak5 show is currently doing a seres of episodes on software defined radio (SDR), centered around the GNURadio Companion GUI front-end. I sampled this episode:
https://hak5.org/episodes/hak5-1602 on decoding an FM subcarrier. This episode skipped over what hardware they were using to receive the signal, but presumably that's covered in the prior episodes in the series. Prior episodes can be found here at http://hak5.org/category/episodes/season-15, such as: Hak5 1524 - Free Software + $20 USB Dongle = Software Defined Radio http://hak5.org/episodes/hak5-1524 Hak5 1525 - Track Aircraft with a $20 Software Defined Radio http://hak5.org/episodes/hak5-1525 Hak5 1526 - Building Software Radios With A Little Bit Of Python http://hak5.org/episodes/hak5-1526 (I tend to access them through YouTube, via an XBMC plug-in, which seems to work better than their in-browser player.) If anyone is proficient with SDR, it could make for a good BLU talk with potentially wide appeal. We all make use of wireless devices, but few understand what is going on down at the radio signal level. An SDR demo would be a way to both explain that and visualize what's happening. Hak5 has covered a bunch of other RF related topics like: Hak5 1511 - Tracking Cars Wirelessly And Intercepting Femtocell Traffic Hak5 1515 - Legally build a 60 Watt WiFi Link - 2.4 GHz and EIRP Hak5 1517 - Point-to-Point WiFi Nodes - OpenWRT Config and Threema - "Secure" messaging for iOS and Android? Overall I'd give the show a mixed review. It uses a blend if "lean back" (overview) and "lean forward" (detailed tutorial) content. I'd rather they stick to the "lean back" aspect and trim the 20 minute episodes down to 10 minutes, and link to written detailed tutorials. (Unless you are watching the show on your computer and entering the commands, watching someone type stuff in a terminal window gets dull fast.) As a result, although I subscribe to this show, only rarely do I invest the 20 minutes to sit through an episode. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
