Up and running. A few observations: 1. Tuner is an excellent performer. UHF loop in bedroom producing excellent signals (built in low noise preamp at loop), with no pixellation on any channels that I receiver. One channel is missing. It is low power and has always had a poor signal. Super sharp pix! Of course the signal meters are reading zero as others reported. I am super impressed with the performance on nothing but a non-multi-path discriminating loop. I expected some multi-path problems and I don't see ANY. When the signal meters start working, I'll compare to the Sanyo, but at first glance, it appears the tuner in the AM21 is superior to the internal tuner of my Sanyo 37". I'll need to do a split and compare signal levels. 2. Setup had to be entered manually. Went without incident. AUDIO BUG REPORT When changing channels from SD local to HD OTA, audio disappears. Changing from one OTA-HD channel to another OTA-HD channel directly from the keypad, no audio loss happens. This is 100% reproducible. Go to a local via satellite and then go to an OTA-HD via the AM21...there will be no audio. It may come after a time, I haven't experimented that far yet. I went into the guide and took out all the SD locals, so now when I hit channel up starting at 5-1, I get 8-1, 8-2, 11-1, 11-2, 11-3, 13-1, 13-2, 17-1, 17-2, 23-1, 56-1 in sequence and the audio is not a problem. If I go 5 sat to 5-1, there is no audio. If I go 5-1 to 8-1, the audio comes back, but if I alternate SD-LIL > OTA-HD, I have no audio on the OTA-HD channels.
