I can here all the Hf spectrum except for that area. I can here WWV on 20, 15, 5, and 2.5 bot not 10. I dont recieve any thing from 15 - 8 megs at all. The noise level isnt even what it should be. Its almost as if that portion just quit. Im running it mobile durring night time and day time operations at verious different time periods on a non-consistant basis. Also I use a Chameleon Antenna.
