I actually get a better signal with the AM21 hooked up to one of my HR22s than my HR20-700. Was your HR20 a 700 or 100?
-700
I was just talking with a good friend in the A / V business about this and we are thinking that there's nothing wrong on our end.
We have had very bad weather here the last week with 4 tornado's touching down in the vicinity of the OTA towers and were wondering if the local channels have been put down to the old reduced power temporarily ....
I will contact the Chief Engineer at one of the locals and see what he has to say.
