I'm in Salt Lake City and for a month or a little more every day at 2:15pm the signal starts dropping out. Drops for a 2-4 seconds, occasionally longer but is frequent for at least an hour then becomes somewhat less frequent. We go home about 4:30-5pm. It must stop dropping at some point overnight because early the next morning (5am or earlier) it is fine until about 2:15pm and it starts dropping all over again.

I've got a Kenwood reciever with an outdoor antenna, which until lately has always had fantastic reception.
