Chamberlain garage door openers NG0G on 5/3/18
I recently had a new garage built. Two new Chamberlain garage door openers were installed and they make 160m unusable. I suspect that cheap switching supplies inside them are using the leads to the switch by the people door, and the wires to the sensors at the bottom of the doors as antennas. Speaking with the manufacture on the phone was a waste of time. They deny their doors emit RF. I can make the RFI go away if I disconnect the door and sensor leads from the opener. I am trying various combinations of bypass caps and ferrite chokes. So far with marginal success.
