To the person who just who just purchased a copy from Amazon of 9th edition of the International Shortwave Broadcast Guide (Winter 2017-18), your copy is not the current one. It has new features for that new edition, but it still has the summer frequency schedules You need to ask Amazon for refund. To the SWL crowd the new edition will be out within the next 24 hours.
