Hi Guys,
I have a particular problem that some of you may be able to help with. =
As I have mentioned to one or two of you in personal e-mails, the reason =
why I have been rather quiet on Topband is neighbour related. I have a =
neighbour who has a touch lamp of which he is particularly fond. You =
may have seen the type - you touch the base and it comes on with a dull =
glow, with further touches increases its brightness, and finally =
switches off.
The mechanism is probably that it picks up stray fields at line rate =
from the person touching the base. Of course, when I transmit, anywhere =
from Topband through to 20m, the thing comes on by itself, usually in =
the middle of the night if I am on Topband.
While I am fully aware that this is not my problem, and have been =
supported by the local authorities in this attitude, in the interests of =
good neighbourliness, I would like to find a solution if possible. I =
have tried the usual ferrite toroid tricks on the line feed, but to no =
avail. I guess the problem is in the capacitive pad itself. The =
electronic block is sealed, so I can't gain access to place caps across =
active devices.
Does anyone know of either, an add-on solution to this type of problem =
or, a similar type of lamp with an EMC rating that covers Topband =
E-fields? I am prepared to buy a new lamp to give my neighbour as a =
gesture of good will, but must of course be careful about any safety =
aspects if I undertake any modifications myself.
