Ham radio is made up by a large number of groups. Here are a select few that I have personally made monitary donations to. I encourage you and your local club to consider the contributions these and other groups are making to the hobby, and please consider supporting them.
All the digital conference proceedings papers and their Packet Status Register newsletter are available on their website. The DCC is an international forum for radio amateurs to meet,
publish their work, and present new ideas and techniques. Presenters and
attendees will have the opportunity to exchange ideas and learn about
recent hardware and software advances, theories, experimental results,
and practical applications.
ARVN - Amateur Radio Video News by Gary, KN4AQ - Documentary and Seminar videos, for and about Amateur Radio (Ham Radio),
on DVD, and now on the web.
Scott, KA9FOX provides web space and services dedicated to the sole purpose of furthering the abilities and interest of the Amateur Radio Community.
Not so-much ham focused, but is a non-profit digital library founded by Brewster Kahle in 1996 that contains a wealth of information available at no cost.
Amateur Radio Digital Communications has been around for a long time, providing DNS, 44 net address space, and tunnel IP connections for interconnecting disjoint wireless networks.
These are just some of of the fine people/organizations providing some really great services and information to the hobby at no charge. Consider taking a moment at your next local club meeting to make a motion to send a donation (big or small) to help support these people who support our hobby.
If you know of other similar organizations, please spread the word.
