Signals have been bouncing here today also, however we have overcast and rain so thats probably a big part of it. TRG, I find Montana PBS tunes in on 12144 sometimes and at other times I can only get it to tune in on 12145, something to try. That is a weird channel for me, normally it is the weakest on that mux but sometimes I will lose everything else during a rainstorm and Montana is still there.
