Dear all,

my neighbour uses a very expensive lovely designer lamp switched by a four step touch switch. Unfortunately that switch follows keying of my mf transmitter. Is there somebody having experience with that kind of malfunction?

The distance to the antenna feeding point is approximately 16m (ANT voltage app. 2.5kV). I tested a chain of eight common mode chokes in series to the affected lamp (mains separation of more than 100kOhms at the desired frequency).

Are there better ideas to keep in use the original touch switch?
