For a point to point propagation prediction that depicts probabilities for each band and allows for determining the best frequency and best time to make a long distance HF contact, please see VOACAP Online. The quick guide for VOACAP Online can be found here.. The manual for VOACAP Online can be found here.. To create a coverage prediction map for any given band, use VOACAP based coverage.

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.

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
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.

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.
