  1. Thanks for re-blogging my post on 10 meters. I hope it will inspire Techs, as well as Generals and Amateur Extras, to get active on 10M as conditions improve in the months ahead. If anyone has questions, wants to provide feedback, or share their 10M station and activities, feel free to drop me a line at james@ab1dq.com – 73 & TNX!
