Also, consider emailing the station directly, worded as technically and
non-confrontationally as possible.

Channel 21 here in Dallas dropped off the map for me a few weeks ago.
emailed them and their Director of Engineering answered they were swapped
over to the lower power auxiliary antenna while doing an upgrade and would
be back up to full power in late January.  Saved me a lot of effort chasing
something I couldn't fix.
