Hey guys,
Just watched the presentation @ derbycon (besides the end sound being MIA it was awesome - www.youtube.com/watch?v=-MgDT4UT7Zk&feature=player_embedded )
I think most people who are interested in this sort of thing should have a look at the RTLSDR devices:
Essentially these are just cheap TV antenna cards (as in they cost $20 cheap) that can be modified to allow you to use them as SDR's (software defined radio) that can be used to receive radio transmissions from about 50-60mhz to 1.4K (which is a lot of space)
These cards mean that people with limited or no RF knowledge (such as myself) can quickly and cheaply get into the world of RF. It also means that all you need to listen is an antenna, netbook and a $20 piece of hardware for your fav. survival situation.
I've written two blog entries on it, however they aren't the best, more used as an introduction for myself into these devices:
andrewmohawk.com/2012/07/15/rtlsdr-my-first-sdr/
andrewmohawk.com/2012/09/06/hacking-fixed-key-remotes/
After that there is another new project based on some USB hardware (technically the TI CC1111EMK usb dongle) that allows both TX and RX from a single usb device. This is the RFCat project found at:
code.google.com/p/rfcat/
Although the output is very low, I suspect with some engineering skills it could be made to transmit a lot further with very few parts.
With these two projects one could easily setup a DIY network for almost no cost.. I would think that would be interesting for people
Cheers,
AM
