Hello Jerry and HD Friends: I just purchased a new STB(LG LSS-3200A) replacing my old DTC100 and can say, without, hesitation, its a major improvement. Since arriving in the Rosman area , I have not been able to get any signal from Channel 4 or 7. With this new receiver, I am now getting a small reading from NBC 4(WYFF) , but its listed as "BAD" on the meter on the 3200A, since it does not list it numerically. This IS an improvement over the DTC100 as I got 'zero" reading with it. So, I have some hope that I can pick up those stations from Tyron. My question is. "Would a pre-amp , like a CM7777 help my CM4228 bowtie. I have done everything with my ant , from moving it up , over, tilts, etc. but have not tried a pre-amp.And, would this cause a problem with those stations from Mt.Pisqah that comes in so strong...Any help would be appreciated! Dan
