Well I have a mountain between myself and the, quite distant, transmitter. Both a weak signal, and also "blocked" by a mountain so no LOS. But I did not have any, what I would call, "trouble" with the NTSC. This apparently is because VHF can somehow get over or propagate around the mountain, and none of my main channels were snowy or otherwise poor with NTSC. And all my main channels back then were vhf. Now with ATSC, and with the help of re-mapping, 3 of my main channels, specifically 2, 4, and 5 became uhf. I have only been able to re-capture 5 now after upgrading to the 91 element uhf antenna.
Sure I can spend more and do better, which I intend to do, but the point is my ability to receive ota degraded significantly. If they were going to change vhf channels to uhf they can figure it is not going to propagate over or around a mountain as well, so should put a repeater on top of the mountain for the MANY people who live on the distant side of it.
So no that's not true, to say the only people that have trouble with digital are those that had trouble with analog, if that's what you are saying. Not true in my case, for instance.
