    Your videos are really helpful I hope I pass! I’m going for both the technician and general on Feb 14th. I’m confident I’ll pass the technical, the general is a crap shoot. Just a technical picky point on this section. You said that the book was incorrect in that WWV doesn’t broadcast SFI,K, and A values at 18 and 45 minutes after the hour only at 18 minutes. They said at 18 OR 45 minutes RESPECTIVELY. I think they are saying that WWV broadcasts them at 18 minutes after the hour and WWVH broadcasts them at 45 minutes after the hour. I just wanted you to know I was paying attention. Thanks for all you do, Rick Cross, Cross Farms (EN75ed) Northport, MI
