This is a collection of articles, generally from QRP-L, about QRP operations and portable antennas. However, anything that looks interesting to me might end up here. These articles are posted here primarily for my own use; however, all are free to browse.

The official archive of the QRP-L mail list, covering the period from May, 2004 to the present, is available at http://mailman.qth.net/pipermail/qrp-l/.

Another, privately maintained, archive that covers the period from April, 1993 to today, is available at http://www.kkn.net/archives/html/QRP-L/. Please note that postings in this archive with dates prior to April, 1993 are legitimate postings but the dates are bogus. The first post on QRP-L was on April 6, 1993; the earlier dates were caused by people posting with their computer date set wrong. (Thanks to Mike Czuhajewski, WA8MCQ, for this information.)

Of course, each author retains copyright for his writings.
