G+_Eddie Foy Posted April 12, 2016 Share Posted April 12, 2016 Somehow I doubt its microwave (aka: over 1GHz) and certainly not radar. But have a handful here to play with. Mainly to see how to beat them. Link to comment Share on other sites More sharing options...
G+_Toby Robb Posted April 12, 2016 Author Share Posted April 12, 2016 5.8ghz apparently. Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted April 12, 2016 Share Posted April 12, 2016 When I get the chance I'll see if my hackRF will do a spectrum sweep. My spectrum analyzer only goes to 3GHz Link to comment Share on other sites More sharing options...
G+_Storm Mcleod Posted April 13, 2016 Share Posted April 13, 2016 This looks fun, hmm Eddie Hack rf rates at top operating freq of 6ghz. err earlier version model only do 3ghz. from what i recall with mike ossmann off a youtube video you can hack it a bit to get better operating freq. theres also port to add in another trans or rev to get full duplex. hope that helps Link to comment Share on other sites More sharing options...

G+_Eddie Foy Posted April 13, 2016 Share Posted April 13, 2016 Storm Mcleod the lower limit on the HackRF dropped from 3MHz to 1.? last year during Hamvention. I asked Mike there about it, its not a real upgrade, just proven to work. No firmware upgrade or anything; just run it. Now I'm also confused about the 5,8GHz. PIR is infrared light, and would not benefit from being switched that fast. So whats the 5.8 for? data back-haul? Link to comment Share on other sites More sharing options...
