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.
