The channels are still there. Can you receive the PBS channels on 12180? Here in Northern California the 12140 signal is much weaker than the 12180 signal (7.8 dB vs 11.4 dB). What size dish are you using?

They're pretty weak here in Minneapolis but I noticed if you move the dish east the quality gains (due to a 12140 V transponder next door at 127W) but then the 12180 mux loses quality
