Pocket FM
- neilwillgettoit 11y agoThis seems like a bad idea. It would make targeting dissent with kinetic means very easy. It's one of the whole reasons that shortwave broadcasts are still around.
- msandford 11y agoHow so? What off the shelf guidance systems exist to home in on FM radio? I'm sure there are tons of anti-SAM guidance packages which will steer something towards a SAM transmitter, but that's in an entirely different frequency band from what I remember. Terminal guidance systems tend to be in the UHF and SHF bands, generally gigahertz and up where as FM is VHF at about 100MHz. It'd take a fair amount of work to re-engineer a guidance package to find such a lower power FM transmitter and perform terminal guidance on it. Especially when the world is awash in FM all around there too. http://thediplomat.com/2014/08/the-f-35-vs-the-vhf-threat/ http://thediplomat.com/2014/08/the-f-35-vs-the-vhf-threat/

- msandford 11y agoIt's a very interesting talk but from what I saw that's not a terminal guidance package by any means. The antennas would need to be too big to fit into a missile. Also it doesn't work very well in an urban environment as the end of the talk shows. There's a huge difference between targeting the radar of an aircraft or a ship or a mobile SAM site and targeting a cell phone.
- neilwillgettoit 11y agoYou don't need a complex guidance package when traditional direction finding and triangulation will produce coordinates that can be used to direct artillery, air strikes, IED, etc. Sigint targeting is quite common.
- gravypod 11y agoIs this someone's attempt at marketing SDR to the masses? This is nothing new, and I'm surprised to see how little information they put forward about it.
- neilwillgettoit 11y agoIt's just a low power FM station with a raspberry pi in it as a controller. It would be highly illegal to use this device in most modern nations without a license.
- voltagex_ 11y agoThe Nokia N900 could broadcast short-range FM with RDS, I'm not sure what advantages this has.
- neilwillgettoit 11y agohigher power. The n900's transmitter was 15nW (1.5e-8 W), which is why it was legal. For a claimed 6km radius, I would assume this is about 3-7W output.
- zumatic 11y agoA 6km radius would fit quite well with schemes like Community Radio in the UK: http://consumers.ofcom.org.uk/tv-radio/radio/a-guide-to-community-radio/ http://consumers.ofcom.org.uk/tv-radio/radio/a-guide-to-comm... ...still need a licence, of course.
