Below you will find charts showing the live conditions around the Earth for radio propagation as well as atmospheric conditions that can affect Ham Radio usage depending on frequency. These are great tools for HF and knowing what the conditions are if you plan on trying to make contacts on a particular day/time. Key for These Charts

HF Signal Propagation and Frequency Accuracy
The outermost F layer supports the majority of long range (skywave) HF propagation while the innermost D layer primarily absorbs 160M, 80M and 40M signals during the day. Ionization (during the day) and dissipation (during the night) is a daily process impacting HF band performance.

Propagation This page contains a dynamic collection of propagation information gathered from many different sources. This data is extremely useful for ham radio operators and shortwave listeners to help determine whether or not long distance radio communications are possible.

Use the indicated color (red, yellow, green, blue, white, etc.) to determine the recommended HF frequencies for contacts from your nearest BASE (New York, Boston, Atlanta, Orlando, Kansas City, Phoenix, San Francisco, and Seattle). Any white "bubble" indicates no suitable frequency or high absorption.
