Welcome to K9LA’s Amateur Radio Propagation Web Site

Carl Luetzelschwab K9LA

On October 21 added my July 2012 Cycle 24 Update presentation in the PVRC link

NEW on September 30, 2012 in the Timely Topics link: Did Cycle 24 Peak in the Fall of 2011?

Reminder: NM7M’s book titled “The Big Gun’s Guide to Low-Band Propagation” is in the 160m link.

Reminder: NM7M’s book titled “The Little Pistol’s Guide to HF Propagation” is in the General link.

I have been licensed since October 1961 (my Novice call was WN9AVT). My interest in propagation goes back to my college days at Purdue University (BSEE 1969, MSEE 1972).

This web site contains selected articles about propagation from my monthly Propagation column in WorldRadio (now WorldRadio Online) and from contributions to other Amateur Radio publications. These propagation articles are grouped into Timely Topics, Basic Concepts, Tutorials, General, 160m, HF, VHF, Contesting, and PVRC webinars. Just click on the link on the left to navigate to these areas.

You may also read about my early Novice days at the WN9AVT link, and my airplane days in the Aviation link.
