(page refreshed every 20 minutes)
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.
The New York and Seattle BASE images provide a general view of global DX from the U.S.
