Have recently started using FT8 to somewhat of a great degree. My wife has come to notice that my operating on 7.074 for ft8 causes the door opener to activate - up & dn w/ each tx. This opener was installed in 2011, & has only one op freq of 302 mc it appears. Any thoughts as to rectifying the issue, tnx, wa9tba

The wall switch button allows strong RF fields to interfere. The control wire acts as an antenna. The simplest fix is to remove the wall switch and control wire and to only use the remote. Alternately, the page describes a more elaborate fix.
