Query: Excellent guide for the beginner !

I don't have alot of shortwave experience, have only really just basically tuned around the various bands, without really knowing much about the way shortwave works. This book really goes into the hows and whys of shortwave listening, and provides a great resource for the beginner!I also really appreciated the radio reviews, since I was considering a new radio, and already had two of the radios listed. I found the reviews to be very accurate, and they helped me make an informed decision on my latest radio purchase. I also actually enjoyed the many advertisements, they also provide interesting information on radios and other products for the shortwave listener.I would highly recommend this book to anyone that wants to listen to shortwave radio, I know it helped me out alot!
