Thanks for your input Mike.
My signal strength for the blinking channels are 92-100%
I've also had other issues with my HR20. Recently I lost 1/2 of all antenna signal strength. After checking several of my off air components, it turned out to be the HR20. I had to reset it and my signal came back. I also lost a couple of channels that were part of my DTV local list, no signal. I rescanned for off air channels and got them back but didn't have programming info. (like the channels not on DTV's local list) When that happened, those channels also blinked. Again I reset my HR20 and got them back and with info. The blinking also stopped when they were back on the DTV local list.
Like you said, I can only hope for some system upgrades from DTV or another HR20.
If anyone else has had similar problems I'd like to hear from you. Maybe we can share some fixes.
Thanks
Capt. John
