Here are some thoughts
WNGS isn't Fox. Its an independent station that has some Yanks, Mets & Indians games (the ones that are OTA) but mainly is an Independent.
The Equity mux has a high FEC (7/8) which pretty much means you need a very strong signal (and be nuts on) to get it stable. It is at
4040
H
29120
I know on my Fortec, the symbol rate scanned in at 29110. Since the TRaxis 2500 doesn't have blind scan, I would try and monkey with the frequency & symbol rate. Try +-10 on both.
I havent personally had a Traxis 2500 but I have worked with a couple. I know for a fact that the frequency can be off to get a quality. To use an example, this particular channel I was trying t lock for the person was at say 12050. That's what my Pansat 1500 locked it on. When I hooked up the traxis, the frequency was 12046. It WOULD NOT lock on 12050. That's how touchy it is.
What I have a feeling is its a combination of a couple things
-dish not alligned right. If its a smidge off you won't get those channels. I have a fixed dish and if I have them locked and lean into the dish I will lose the channels.
-The Traxis isnt the most user friendly mainly because of no blind scan.
Just a stupid question...since the 4DTV is hooked up, you do have it set to H polarity, right?? Also, try and adjust the skew on the dish. A little bit may go a long way
