Not only will you find issue #111, but all previous 110 issues as well.

This stuff is really amazing. Issue #111 is 17 pages full of homebrew
goodness. It includes articles or short notes on:

A couple of different simple receiver circuits.
Analog switched-capacitor circuits
Amplifier classes.
VXOs.
Homemade HV capacitors for loop antennas.


The editorial opines on why we should build things ourselves:

Small is Beautiful?

E.F. Schumacher went to great pains to explain how technology has debased
human creativity and more or less destroyed ‘job satisfaction’ in his book
“Small is Beautiful�. Technology diminishes the human appreciation of time
well spent; it removes the human element to a great extent and offers
convenient, but very limited, mental satisfaction to the user.

Think on this applied to your home constructed radio receiver. It might not
have all the features a “bought in� receiver offers; it may well struggle
to equal the capabilities, or the diversity of functions. But and it’s a
huge ‘but’ YOU made it. YOU put it together. YOU can modify it, improve
it, try different approaches. It’s YOURS, and belongs in every way to
YOU, not some distant designer who’s Muntzed the d*mn thing down to the
lowest price, used midget components only a robot can manipulate, and needs
a trained microbe that can solder to repair the blasted thing.

Seriously, take a look at these newsletters.
