[bars] Radio Book

[apizer at comcast.net]

I second the opinions on the value of older reference material though I have not read this text.  The basic laws of physics, energy transfer,  and math have not changed.  No matter what the technology is “in between”, it is acoustics that drive the microphone and electromagnetics that drive the antenna.  A joule is still a watt-second and power is still dissipated as heat if not transferred to the load.  Here is a controversial thought - - maybe folks were just smarter back then because the had to be - - things were not handed to them on “silver platter” as they are today.  I have spent 45 + years mentoring colleagues on the nuances of RF test and measurement and it starts with the basics.

I hesitated to add my two cents, because I felt a dismissive tone to your comment. I apologize if that was not the case.

Regarding what you said, all you said is true. Otoh, basics are still basics - a triode amp is still a triode amp whether a tube or a transistor. A tuned circuit is still a tuned circuit. A center-fed dipole is still... ditto. Same for rectifier circuits, parallel and series resistors and capacitors (omg, does anyone still use discrete components <g>?). And well-written books were created even 85 years ago.

I still periodically refer to a calculus text I inherited from my father.

Now, if I could somehow get that text in a .pdf file so I could access it on my tablet using my personal VPN<g>.

What are the chapters on SSB, Solid State circuits, FET's, digital modes, automatic tuners, antenna analyzers, satellite contacts, Spread spectrum, SDR, Method of moments antenna analysis. Digital signal processors ... what kind of feedlines does it cover?

 

It's easier to write a handbook when half the stuff hasn't been discovered yet.  Now that everything is simplified for you - have you tried to get the rigs and parts that are simplified for your understanding?

 

What exactly did you learn from it that is of use to you or anyone else?

Picked up a copy of The Radio Handbook, 1938 edition, for a couple of bucks several weeks ago. I started reading it today and realized it beats the ARRL handbooks by a long mile. Easy to read, concepts well-explained. $1.50 in 1938 would be $31.95 today.
