Hi ... got a 622 and the Winegard Square Shooter. Having trouble with 2 different channels brought in. Seems most of the problems happen during HD programming but here is the problems. My CBS loses audio once in awhile and the only way to get it back is changing the channel and coming right back. It gets over a 90 on the signal strength. Now my ABC is acting up. It draws an 85-89 signal strength but it flicker on and off and is constantly losing signal even with a decent signal strength. My tech is confused and I am wondering if anybody has any ideas and run into this before. This only happens on the OTS signals not on the Dish channels. Help!
