I used to have a sw64, I got tire of losing signal so I bought a 3 dp lnbs and a dp33 switch. They are connected to 3 dual tuners. Now from time to time I got a Complete signal lost message. Its not a rain fade problem. Sometimes the problem is in one tuner, other times in my kid rooms (other receiver). Its driving me crazy. If worst than the sw64. Are dp33 reliable? I doubt is the wiring, is practically new. Any ideas?
