Apparently Shaw Direct TV has adjusted their satellites recently to deliver only HD signals. My current Direct dish and Winegard Trav'ler automatic Multi Satellite TV Antenna SK83 will now not lock on to their sats. Neither Winegard nor Shaw has any answers to correct, and neither knows of any kits available to upgrade. Any other folks having "issues"?. The units worked great Aug 11,12,13 and stopped on or about Aug17. Thanks for any comeback
