Let's forget about the door, its springs and torque adjustments. This
is an RF problem! Neither a new remote nor the original remotes will actuate either the new receiver or the old receiver. Has nothing to do with the door itself or the closer. There is something near that physical location that prevents the receivers from getting a valid signal from the remotes. I am looking for ideas as to what that might be. This is an all-house neighborhood. No businesses of any kind. Nearest thing other than houses is a high school two blocks away. Power lines are overhead, not buried. I think you're going to have to find something that's capable of acting as a spectrum analyzer (or at least a crudely-tuned RF sensor/signal-strength-meter) and start DF'ing. A ham HT with 70 cm capability, and a 'scan' feature, might be enough to find the signal frequency fairly quickly if it's strong enough to interfere with Part 15 devices. Then, start hunting. A simple hold-it-near-the-chest-and-spin-on-your-heels 'body fade' might be enough to allow you to triangulate in on the source. A two- or three-element Yagi hooked to a real spectrum analyzer would probably be rather faster. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
