Re: [IRCA] propagation article

Well, yeah, that was new term for me as well. I did a web search and found
an interesting article by Bob Brown NM7M PhD UC Berkeley (
http://www.astrosurf.com/luxorion/qsl-hf-tutorial-nm7m5.htm ) and I found a
short explanation about halfway down the page. Maybe I can read the entire
article.

Last winter, while still living in S.E. Michigan, I may have experienced
this phenomenon when in just one evening session, I logged 7 NDBs from
Nunavut (6 of which I had never heard before).

Here's hoping this will shed some light on things.
