Teaching myself radio

7 posts in this topic

So I looked up spark-gap transmitters, Poulsen Arc-Converters, and I'm working my way to vacuum tube tech. Most of this is learned off wikipedia.

What I'm looking for from you guys is info on:

+Antenna design

+Practical materials on building/designing primitive radio gear

+Anything else that's relevant, since I'm just getting my feet wet and can't even tell you what I'm supposed to learn

What type of radio are you interested in? First thing would be to learn about the different types of frequencies across the scannable radio spectrum so that you know what types of materials (antenna, receiver, software, etc.) you need. To do this, you can have a listen to the "Off the Grid Voice/Data Communications" talk from The Last H.O.P.E. Conference...

http://www.thelasthope.org/talks.html

You can also view the FCC chart delineating frequency allocations...

http://www.fcc.gov/encyclopedia/radio-spectrum-allocation

Once you get a basic sense of which frequencies you hope to send/receive on, you can get a better sense of what type of tools you need.

I'm really just interested in general theory and design for transmission of radio waves. I'm planning on using the same principles to build a (relatively) low-power directional EMP device.

Edit: Obviously not for destructive or illegal use and I will not be providing anyone with information to build anything that could be used for illegal and destructive means, please do not ask.

I have a textbook on Microwave Engineering by Pozar, is there any other source anyone could recommend for learning?

I just redid the archive of all my past hacking work, much of it RF-based, at http://www.oberonsrest.net/. Lots of good stuff there!

I also suggest checking out the following primitive radio resources:

Anyone interested should look at Microwave Engineering by Pozar, it's an excellent textbook.
