A small caveat. receivers, esp consumer ones, are NOT only sensitive
on the freq tuned to. Put another way, the received bandwidth is
not infinitely sharp, with infinite cut off. It is quite possible,
esp in high field situations (8)>>) for a signal with NO energy at
'f1' to be, apparently, received at 'f1', because it bypasses all
or part of the 'front end'.
==========================
A possibly silly suggestion, in re construction of capacitors:
It was mentioned that stacking up multiple sheets of dielectric, to
get higher withstand voltages, created difficulties, in that the
sheets slid around.
Would it be possible/desirable to temporarily bond the sheets together,
say along one edge, to avoid this? Using heat, or solvents, or
whatever, possibly even leaving an extra strip of dielectric for the
purpose? Once the assembly was complete, the 'extra' strip might be
cut off, avoiding any potential (8)>>) problems with the eventual
voltage stress on the modified area? (Or simply make the sheets
oversize, so that the 'bonded' area was outside the area subject to
high fields?)
