My, this is embarrassing.
This one's working now. After repeated attempts to get it to work a few months ago, I pulled it loose and set it aside. Now it's working great. I'm doing a channel scan, it's finding the channels downloading the program guide and letting me watch them again. go figure! The tuner in the DTVPal is better at pulling in stations than the one in the TV!
I'd go out to the motorhome and get the other one to try it again but it's raining right now - first time here in St Louis in 6 weeks - it only got to 98 degrees here today - for the first time in the last 10 or 11 it didn't make it over 100! Tomorrow it isn't supposed to make it to 90! Time to rejoice!
Thanks for your help and when I can drag the other one in here, I'll give it another try before I jump on the forum.
Thanks again, your responses are deeply appreciated.
