In conjunction with the Gordon West book, these CDs might be a helpful reminder/re-enforcer of material covered in the text. I find the ARRL manual, which I used, to be reasonably well organized, and these CDs do little to augment that. If you want to understand the concepts you can skip these, use the ARRL book. If you need to memorize the material, these may be marginally helpful - but then buy West's book too. In either case, good luck & "73".

We purchased 5 of these mats for our Sunday night yoga and they're wonderful. The students love using them. Thanks.

Fifth visit to the Hess line for this grandfather, with as good a result as the first, second, third, and fourth. I have yet to order a vehicle that did not match the description in Amazon's online display, including both new and used models -- commendable both for the online store and its suppliers. Given that this is a Hess truck, I have faith that it will survive the crash! boom! bam! that awaits -- the others have weathered their years splendidly.
