There are consistent and regular dropouts in the audio on KSPS PBS Seattle, especially on the British sourced shows, sometimes they are accompanied by abrupt changes in level. This is from a North Vancouver viewer
I also responded to one other person's complaint. I am having frequent audio dropouts (they last long enough to miss out on one word). I have the problem on the Minneapolis ABC and NBC channels. It probably happens on other channels as well. This happened before. It was not my equipment.
