found this on AVS but didnt research it independently. I wonder if it will help my non night reception now going a bit lower on UHF?: Reception Alert! Please be advised that WHYY-DT will be off the air beginning mid-day Monday, 10/16 for 2-3 days for technical changes. When the station returns to the air, WHYY-DT will be operating on UHF Channel 50 at the same power and antenna location. To receive WHYY-DT off-air, you will need to rescan your DTV receiver or enter the new channel 50 location into your preset channel memory. This channel change has been authorized by the FCC to enable WHYY to test prototype convertors and other advanced technical components. Our apologies for the service interuption. We are working with Comcast to hopefully continue the digital service on Comcast cable during the off-air transition period. Bill Weber Chief Technology Officer WHYY, Inc.
