I am not sure what you mean by *jam*, but the spokesman in the article says it does not involve jamming of any kind. Non-military jamming is completely illegal in the US and most countries. I believe fake GPS signals would also qualify as jamming. Perhaps they sell special stickers like the ones to put in your cellphone to increase range and reduce dangerous radiation :) Bob On Sat, Mar 16, 2013, at 06:11 PM, YES NOPE9 wrote: > http://www.usnews.com/news/articles/2013/03/15/oregon-company-to-sell-dro= ne-defense-technology-to-public >=20 > Any ideas about how they plan to do this ? > Blind the camera ? > Gus --=20 http://www.fastmail.fm - IMAP accessible web-mail --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
