It is true that there are only so many frequencies. But with modern alarm systems this is irrelevant. All current systems (unless they are total junk) use digitally-encoded signals with millions of unique codes. Moreover, most of them use "rotating code" schemes that protect against "captured" codes and other spoofing techniques. The days when an airplane flying overhead could cause your garage door to open are long gone. --Pete Lucas VIN #06703 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
