Propagation charts are no longer printed in QST. Instead, they are provided here in Adobe PDF files. You'll need Adobe's free Acrobat Reader (version 3.0 or later) to view and print these files.

Charts are now calculated to cover calendar months. The file for each month will appear here on the 25th of the preceding month.

Starting with March 1999, there are separate charts for each US region. Stations located in a region of the US can download just the file needed for their location.

About the Charts

Information about interpreting the charts can be found in two QST articles, made available here as PDF files:

• "Those New QST Propagation Charts," by Jerry Hall, K1TD (Oct 1994 QST, 43,247 bytes)
• "Interpreting QST's New Propagation Charts for Low Power and Low Antennas," by Jerry Hall, K1TD (Feb 1995 QST, 177,001 bytes)
