we are experiencing interference on our garage remotes. We have two garage door openers running at 315mhz. Other than power, these are two separate systems and both have deteriorated simultaneously. At the same time, our neighbor reports that the key fob on his suv is no longer working when at his house. The car is fine anywhere else.
our garage has an aluminum door and siding. Before I heard from the neighbor, I bought an antenna kit from lift master and moved one antenna to the outside of the building. I should not that the antenna is screwed to and os parallel to the metal siding. That helped some. We can now open the door if the car is within 20 feet.
my thought is that someone has installed something around here that’s causing problems. What I’m doing here will help but the real solution is to find the culprit.
I was looking into an rtl-Sdr that can hook up to my android phone and maybe go on a fox hunt. But I would need some advice. I’m looking at rtf-SDR.com where the offer a radio dongle and then I thought I would build my own cheap directional antenna.
so, anyone have suggestions?
