Yes, also the Ham Interfacing pdf.

Not really. In fact, it is written for hams WITHOUT a college technical 
education, but who have done at least some studying of electronics and 
how radio works. You studied for and passed a ham exam, and I assume you 
have a copy of the ARRL Handbook.  We are not CB operators, we are 
expected to have some technical capability, and to be using our licenses 
to expand our technical capability.  My stuff is written for those who 
want to learn.

Yes, it can be a major challenge to rebuild electrical wiring, but if 
you STUDY my material, you will find that it is far easier than you 
think.  But you DO have to study it.
