Home security system QRM

February 8, 2010 by Arvadmin

Reports are starting to appear about a security and home control system that uses the spread spectrum protocol at 100 milliwatt, and at a distance of 100 metres its emissions make the 40 metre band unusable.

The system has its signal at a two to five second rate, from 7.1 to 8.5 MHz. That's not only 40 metres but also the spectrum used by broadcasting, aeronautical and marine radio. Be alarmed and alert for this system arriving in your neighbourhood.
