Hi ... got the 622 last week and the Wineguard Square Shooter. Most channels are wonderful but the channel with the highest signal strength has audio dropouts from time to time. Needless to say it is very annoying. Get a 93 signal strength so that is not the problem. Could this be a receiver problem or what can I do next. Seems to happen when a show is in high definition. It is my CBS station. Any help ... I am a newbie!
