HamWiki

The hamwiki.com and hamwiki.info domains have been "parked" by cybersquatters and are therefore no longer usable websites. The hamwiki.org / hamwiki.net domains do contain one mediawiki with little content, but the site sadly is abandoned and overrun with linkspam.

Possible alternatives are:
 * http://www.amateur-radio-wiki.net - Amateur Radio Wiki maintained by VK4YEH
 * http://ab9rf.com/wiki - Kelly Martin, AB9RF

and:
 * http://wiki.bcwarn.net - British Columbia Wireless Amateur Radio Network
 * http://pitfall.org/jplarc - JPL amateur radio club (US Jet Propulsion Labratory)
 * http://rocwiki.org - Rochester (NY) amateur radio association
 * http://www.zerobeat.net/mediawiki - specific to the Elecraft K1/K2/K3 series of user-assembled ham transceivers
 * http://wiki.ham-radio-deluxe.com - for the Ham Radio Deluxe series of computer programmes for amateur radio operators
 * http://wiki.radioreference.com - various radio topics, including radioamateur, public service, land mobile and scanners
 * http://wiki.nycresistor.com - NYC resistor, a local club in New York City
 * http://qslogbook.com - The Amateur Radio Social Network

Description
No clear goals, but attempting to be an ham radio mentoring wiki, except that it discourages editing, and discourages linking to wikipedia, but copies wikipedia content without credit.
