These signals are frequency stable and not drifty. Shutting down the
house-mains with the receiver battery powered does not kill the QRM.
How about your garage? I have two new Chamberlain Garage Door openers
that have cheap Chinese switching supplies in them that use the wires to
the switch at the people door and the wires to the sensors at the bottom
of the roll up doors as antenna. Despite toroids and bypass caps they
wipe out 160m. When I know we are in for the evening I power them off
at the circuit breaker panel.
