I just received a flyer from our local technical book store, Virginia Technical Books. Their Herndon store is sadly closing, a victim of the on-line stores. They are running a 15-40% off closing sale. See www.vtbooks.com Store hours M-F 0900-2000, SA 1000-1800 . 131 Elden St. Herndon. They have a good selection of RF/EE-related books. They will be missed. Tracy Wood K7UO
