am having problems with my local channels only with the ones coming from my AM-21
1. on all local channels with .1 numbers after about a half an hour the audio starts cutting out until it goes out completely. changing the channel back and forth fixes it but the problem comes right back. Am having no problems with the regular locals with no .1 behind it.
2. when I scroll through all the local channels, every time I get to a channel with .1 after it the banner screen comes up for about a half a second and disappears. does not do this on the channels without .1 after it.
I have tried all types of resets on HR-34 and AM-21 to no avail.
