So this is a fun one for me, in my mountain neighborhood near Bellingham WA. We have a local 250W xlator that repeats classic hits KBAI 930 (K-Bay)- but the HD1 from distant KPNW Seattle tends to capture it in some locations as I am on the edge of both service areas. SO in the course of a few hundred hard drive you might switch back and forth five times with clear sounding signals on each. I think KPNW's HD signal heading northbound overshoots it's analog by a bit so we end up with this situation. I can imagine someone who has an HD radio in their car but is not super aware of this would be perplexed.
