Yesterday I flew from Everett WA to Ashland OR. I saw a warning about sun spot activity being unusually high Fri and Sat, and sure enough several times during the 2.5 hr trip my garmin 396 showed a warning No gps signal. I also have an iPad which would not track with the gps the whole trip. Occasionally it would indicate 20 to 30 miles off. I have a panel mounted Bendix/king kmd150 which tracked perfectly the whole trip. All 3 units worked perfectly to and from OSH earlier this summer. So I conclude these sun spot warnings of gps interference are REAL. I tuned in my VOR just in case the King failed also. The vors worked as usual.
