Sun

The SHOW/SUN command displays the sunrise and sunset for the specified country.If the exact country prefix is not known, enter a valid call for the country and the Cty prefix will be automatically determined.A SHOW/SUN without any callsign defaults to the sun data for the userís location.SH/SUN also works on US call areas of K0 through K9, resulting in the sunrise/sunset being shown for each state
