It's just a book that gets published annually and then becomes out of date. I wish that WRTH would have a database subscription of the frequencies that are on the air though a android app or PC app. The book is good for offline DXing, just hoping that the information is good until the next copy comes out. I was looking at the long wave stations, and Radio Rossii should be removed from the page because they went permanantly off the air in January 2014. And some other stations are going off air too that are in this book. It's only good if you like days of new radio history, but frequencies get on the air and then leave the air according to the internet. I wish that they would add all of the US TV stations in this book since it's a TV handbook, I remember back in 1992 through 1994 they used to have big dish satellite listings which made me be full aware of the satellite stations available. Now it's just TV channels from different countries that require special TV decoding equipment, which is good for a international broadcast engineer more than a DXer. I think this book should be published every 6 months without the television information included, because who needs the TV information unless you're travelling to that country. Now the AM stations in the book are good and fresh, but the short wave and long wave stations, better keep up with that type of information online. The FM stations are good for FM DXer's, but does not include stations from every city which they should make another book for all FM stations some of those stations become out of date from loss of funding, loss of license, license revoked, or natural disaster causes. The verdict is : Make this book as your offline radio reference source and make sure that you get it every year to keep up with the major changes in radio broadcasting. Great book for DXer's, engineers, general radio listening, Hams, pirates, technicians, repair shops, electronic businesses.
