I built the 'LNP loop and found the balance difficult to achieve without
a
good deal of component value fudging. The performance was poor and the
signals lacked 'presence'. I disconnected the amplifier and put a couple
of additional turns to form a pick-up loop, which was then fed into a
Datung converter, which worked much better. I will implement a couple of
suggestions, on this reflector, to improving the amplifier and report
back.

When I compiled the Low Frequency Handbook I made a point not trying to
include information which was already in the LF Source Book. The main
exception was Bill Bowers contribution on coil design.

I thank you all for your kind comments and update information on these
books.
