Dear all=2C

=0A=

my neighbour uses a very expensive lovely = designer lamp switched by =0A= a four step touch switch. Unfortunately that switch follows keying of my = mf =0A= transmitter. Is there somebody having experience with that kind of =0A= malfunction?

The distance to the antenna feeding point = is approximately 16m (ANT =0A= voltage app. 2.5kV). I tested a chain of eight common mode chokes in seri= es to =0A= the affected lamp (mains separation of more than 100kOhms at the desired = =0A= frequency). That showed improvement in sensitivity but the switch did not= work =0A= anymore during transmission. The most effective solution is replacing the= =0A= touch switch by a normal dimmer.

Are there better ideas to keep in use the = original touch =0A= switch?
