Interested in radio history, ITU conferences for the past 100 years gradually going online

This is a quickie, but a goodie.

I’m fascinated by radio and communications history.  There are a lot of great tales.  From the early radiomen of Marconi, DeForest, Armstrong up to today with the big corporate discoveries and advances made by hobbyists.

Every few years the ITU holds conferences, called “Radiotelegraph and Radiocommunication Conferences”.  These conferences are international gatherings of major governing bodies to discuss trends, coordination issues, technology, etc.  As amateurs, we especially notice the coordination issues every 40 years.

The ITU has started digitizing these documents recently and making them available online.  Some of them so far are:

* Preliminary Conference on Wireless Telegraphy (Berlin, 1903)
* International Radiotelegraph Conference (Berlin, 1906)
* International Radiotelegraph Conference (London, 1912)
* International Radiotelegraph Conference (Washington, 1927)
* International Radiotelegraph Conference (Madrid, 1932)
* International Radiocommunications Conference (Cairo, 1938)
* International Radio Conference (Atlantic City, 1947)

They are adding more and on their site.  There is a list of proceedings they will be making available in the future there as well.

Sometimes….. the best things in a hams life are free!

E-books!

I love ‘em.  I also buy a lot of the CD/DVD’s with PDF’s of old books and mags on ‘em.  They sure come in handy when you’re sitting in an airport with a lot of time to kill.

There are many publications you can purchase on CD/DVD like all the ARRL magazines and some books, QRP-ARCI has all their mags on a CD.  At Dayton’s past, I’ve also purchased “update” DVD’s.  Ham Radio Magazine is available through the ARRL on CD (though the league did some really goofy stuff with their older publications, I do prefer PDF’s and even started converting much of the older stuff myself).  World Radio Magazine is freely available online now (no longer in print, but new issues).  I think the CQ magazines are still available as  well, but they had a weird subscription where you download portions of a mag and such (I never did understand that one).

Here, I’ll list a bunch of stuff I have had on my PC for a few years and some newer stuff available online.  If you know of any that you think would be useful, either reply or email me (mycall@arrl.net) and I’ll post them in a future post.

I’m going to add a category called e-books to mak finding these a bit easier.

Let’s start with DXpeditioning Basics from Wayne Mills, N7NG.

Originally written in ’95, this is a neat little publication that can help out a portable operator.  If you play portable in a park or fire up a few IOTA spots, this book has a lot of good information.

In addition to topics like planning, pileup management, organization and such, I really like the chapter on ethics.  Not that we can use a little more of that! (OK, well, at least on 80 meters!).

This ebook is available from the ARRL, direct download at:

Now look at that picture, don’t he look like a happy guy!  Portable operating is a lot of fun (and it’s not just for Field Day and EmComm anymore!).

Speaking of ethics, there is also a good publication that has been making the rounds of late on various sites from John Devoldere, ON4UN and Mark Demeuleneere, ON4WW called “Ethics and Operating Procedures for the Radio Amateur”.  This is a well thought out document that can help many new HF ops not come across as “lids”.  I’m listing the .pdf version here, but there is a PowerPoint version floating on the web (practice your google-fu) in case you’d like to give this as a presentation at a hamfest or club meeting.

A few years ago, I came across a neat little book by a Frank W. Harris, K0IYE called “Crystal Sets to Sideband”.  This book is really neat and covers a LOT of information for getting started in ham radio.  Rather than go into a long rant, here is a listing of the table of contents:

Table of Contents:

Chapter 1 – THE FASCINATION OF RADIO
Chapter 2 – HOMEBUILDING AMATEUR RADIO EQUIPMENT
Chapter 3 – SETTING UP AN ELECTRONICS WORKSHOP
Chapter 4 – HERTZIAN WAVES IN THE BASEMENT
Chapter 5 – GETTING ON THE AIR – DECIDING WHAT TO DO FIRST
Chapter 6 – BUILDING A QRP HOMEBREW
Chapter 7 – BUILDING A CODE PRACTICE RECEIVER
Chapter 8 – POWER SUPPLIES
Chapter 9 – ACCESSORIES FOR THE TRANSMITTER
Chapter 10 – VARIABLE FREQUENCY OSCILLATORS
Chapter 11 – Building a VFO for the higher bands (PMOs)
Chapter 12 – FINAL AMPLIFIERS
Chapter 13 – BUILDING A HOMEBREW HF RECEIVER
Chapter 14 – OLD-TECH VACUUM TUBE RADIO
Chapter 15 – THE NOBEL PRIZE FOR SIDEBAND
Chapter 16 – ANCIENT MODULATION

As I did in a previous post, I’m going to recommend a Mozilla/Firefox plugin that makes downloading thse a bit easier.  DownThemAll! makes downloading multiple files on a page MUCH easier.

The DownThemAll! plugin is available here: http://www.downthemall.net/

Crystal Sets to Sideband is available at: http://www.qsl.net/k3pd/book.html

This next one is for those interested in microwave radio.  Paul Wade, W1GHZ has a neat publication available called “The W1GHZ Online Microwave Antenna Book “.  As with “Crystal Sets to Sideband”, I’d recommend using DownThemAll!, this has a lot of files.  But an interesting read for amateurs, even if you don’t hit the microwaves yet.

His book is available on his site at: http://www.w1ghz.org/antbook/contents.htm

And finally, though not a book, there was a great series of articles in the 80’s that the ARRL published in QST that had a lot of information for new hams called “First Steps in Radio”.  I use this series as handouts when I teach a new radio class as it is still very relevent today.

The index with the downloads for all 19 pdfs (again…. DownThemAll! is your friend….. but I’m being redundant here…) is available at:

http://www.arrl.org/tis/info/frsteps.html

That should get ya’ll started for now.  I know I have links somewhere for a bunch of other similar ebooks/docs online.  If you have any good links, post them as a comment or send me an email.
