I have the Zenith, but I don't get any buzz.
Last night it was raining and I got some intermittant signal loss in the basement tv. Occasional pixelation.
I switched to a different antenna but I don't know if that was it or just improvement in the original signal. There was no problem on the upstairs tv. The basement tv does get fewer channels found.
When I first set up I noticed on the upper channels the audio sometimes seems out of sync with images - like voices are dubbed, but after awhile it seems to match.
And sometimes the digital image seems just a little cold and jerky compared to smoother analog.
I can picture it now. People will wax nostalgic about the old days of analog being more tube-like versus digital like LP vs CDs!
