WNWN is another one I haven't heard yet. I thought it might be a semi-local pest for you...

I did hear a National Anthem and s/off at 8 p.m., but never caught the ID. WKDO seemed to drop power right then, too - but they don't have night power. I also had a female ancr with a call-in talk show that peaked a couple times, but never during a break. Also caught KLNG with religious programming. Still no KGOW here. :(

America needs a sense of humor...
