I thought that possibly my problem was tall trees around my house but a friend of mine with no trees and a Hughes receiver was having the same problem simultaneous with my problem. My signal strength meter on the receiver shows a "good" signal most of the time but intermittently it drops off to bad to no signal as the problem occurs.
I would guess that I am about the same distance from WFMY as you are from WXII and WUNL, that is 30 miles and 25 miles respectively. Certainly the 4228 should do a good job considering its specs. I am not familiar with the RS pre-amp. Is RS a brand? I assume you are using a rotator, yes? About how long is your cable run? Where did you get your equipment? Thanks for your help.
By the way, have you received much response to a meeting?
I have noticed if the wind is blowing, I will have drop outs on WXII-DT and WFMY-DT is a hit and miss thing. I didn't see any of the Bronco's/Colt"s game, but tonight on CSI:Miami there was considerable macroblocking, the worst I have seen on WFMY, and it was on everything from CBS. Since they didn't switch to any local stuff, I don't know if it was their sat feed or my receiver.
I personally have been suspect of their network feed. I have seen macroblocking on some shows and then switch to WDBJ-DT Roanoke and not see it. I am assuming they are receiving their HD signal the same way they get their SD signal. Because of terrestrial interference (TI) at Phillips Ave on their CBS dish, they have had their CBS dish at their transmitter at Level Cross for many years and microwave it back to Phillips Ave. I am assuming they are doing the same thing with the HD signal and that may cause additional problems not seen with other CBS' like WDBJ-DT and WRAL-DT. I don't know. I have seen break up on WFMY-DT when my flee powered signal was solid and it should be the other way around when you figure that we are running 4200 watts at 900 ft and WFMY-DT is running 500,000 watts at 1900 ft. They are using a different encoder than we are and I know it is an earlier generation than ours. That too may have something to do with it. Again I don't know.
My antenna setup is pretty crappy by design. When I put it up in April of 2002, it was to mimic a worst case antenna setup and still pick up WGHP-DT. I run 100 ft of crappy RG-59 (I only need 50 ft) and a cheap Radio Shack (RS) pre-amp that gets overloaded easily and it is mounted on a not so stable tower section lashed to my fence at 15 ft up and so every time the wind blows, the antenna blows around pretty good and I get bad drop outs then. Worst of the worst and I do OK. I am getting tired of the break ups so when the weather breaks, I am going to install it on the roof with a good Winegard pre-amp that I have and about 50 ft of sat quality RG-6 so my reception should improve even more.
I have noticed if the antenna is not pretty flat to horizontal, it will break up pretty good. It could be you are also having multipath issues. Best way to check is look at an analog signal on your antenna and if you see lots of ghosts on channel 48 analog that could be a factor as well. (Use channel 48 analog since it is beside WFMY's tower and WFMY's DT channel is 51, so it is in the same RF neighborhood. Comparing channel 2 analog with channel 51 digital is no comparison since channel 2 exhibits completely different propagation characteristics than any UHF channel.
I would start with that. Those are the most obvious and easy to check.
And no, I haven't heard anymore on a get together. I would hope now that the holidays are over, maybe we can get together, (a Super Bowl Party at someone's house who has a theater they want to show off or something?) or a restaurant. I defer to others on that.
