Hosted at Hans Summers' Radio, Electronics and Computing Projects web
site, and authored by Len Anderson, K6LHA:

Looks like a concise and lucid work about radio frequency engineering,
both analog and digital, that is accessible to the amateur hobbyist.
Initially published in 2014 by an author who clearly has had
professional experience in the field, but is able to patiently and
accurately communicate it to a wider audience.

It also appears to be a work in progress, and future chapters on other
topics may be forthcoming.
