We are experiencing a loss of reception on a variety of channels lately but not all channels. Channel 15 is not coming on at all and channel 209 is experiencing some fairly severe pixelization. there are 4 or 5 other channels that are experiencing some forms of either a loss of sound and pixelization or both. These other channels are not as affected as channel 209 is. Not all channels are affected. Is there anything that can be done to correct the situation as this has been going on for a couple of weeks or better. Now we have lost 209 all together as well.
