KV5R’s Ham Radio Articles

NOTE: April 2013— All KV5R’s articles from both athensarc.org and the old kv5r.com site have been integrated into this new site. Several dozen redirects have been provided to handle the old .asp URLs, but please update your links! Thanks!

This is the site where new—and not so new—hams may find a wealth of articles on easy-to-build projects including antennas, radio add-ons, tips and mods, making your computer play with your radio, getting more into HF radio, understanding antennas without all the engineering lingo, building great (and cheap!) antennas out of hardware junk, locate repeaters and scanner lists, etc, etc.

Get the kids involved! These articles are all about having more fun with ham radio!
