I am having trouble with my kvh tracvision lm aquiring a sat. it did it when i installed it origionally but it did not hold it for more than 10 minutes and about 5 mile. It will run and spin looking for the sat stop and show tracvision lm then rq 3.21 then insializing for a couple of seconds and then move on. it will go though search 1 then 2 then 3 and then start over again. Any ideas
