MFJ-8100
World Band Receiver
4
receiver kits offered by the major radio companies of several
decades ago. (The fondest dream BACK THEN of most of these
radio builders was to be able to afford to move up to a
"superhet communications receiver.'' Their fondest memory
TODAY is that very first receiver kit.)
From the late 1970's through the '80's, as consumer
electronics and new ham radio equipment became more
sophisticated so very rapidly, interest declined not only in
regenerative receivers, but also in kit-building and even in
shortwave radio listening. One or two generations of
Americans simply missed out on the thrill and satisfaction of
building AND UNDERSTANDING a simple radio set which could
receive signals from anywhere in the world.
Back to Today and the Future!
Your MFJ 8100 is a much better receiver than the "classic''
radio sets which attracted several generations of Americans
to the excitement of radio and electronics. In fact, its
basic performance is superior to many of the simplest
superhet receivers which were considered such a great step
beyond one's first regenerative set.
The reason why this receiver works so well is because there
is much more precision in today's engineering designs and the
manufacturing of electronic parts. We looked carefully at
the practical problems associated with yesteryear's
technology, and we used TODAY'S know-how and components to
solve the problems.
A Simplified Explanation of How It Works
When you're ready, please explore the technical explanation
of your receiver in "Introduction No. 2.'' In the meantime,
you can peek at the schematic diagram and picture the
receiver in three basic sections:
A. Detector-Oscillator (Q1,Q2)
B. RF amplifier (Q3)
C. Audio amplifier (IC1)
