Satmex6 - MAC TV and IAVC signal quality problem

[dchieng]

I have Sadoun 31" dish and Mercury II RX with universal LNBF. A few weeks ago I had it pointed to SatMex6 and scanned 2 TP's for FTA channels, one is 12080H for CCTV4, DA-AI, IFTV, the other is 12090V for MACTV and IAVC. I never have any problem with 12080H channels, but during the day, the 2 channels on 12090V constantly break up and a lot of times just not watchable. But at night times say after 6:00pm, they will be fine. Any clue why? My location is Austin, TX.

Both have good signal level, but I noticed 12090V has lesser signal quality that 12080H by 10 "unit" or so, day or night. Do I need a bigger dish? Or better LNBF? Or SatMex 6 is having broadcast issue.?

I usually don't watch this during the day. The problem could be weather related so a bigger dish can help. I find no difference between LNB 3 vs 4 Ku. You can try to optimize your dish as much as possible. If you have a stationary setup. Try this. Make sure your LNB is push as far away from the dish as possible. Turn your LNB slightly to the left and right while someone is watching the signal strength. You should be able to peak it around 60%. Make sure your pole is in solid, no wiggle room. Use RG6 cable. Use the best connectors (satellite grade) no the regular ones for cable tv. Make sure no trees or other obstruction is in the way.

I have tried this on many clear days and no difference. I tried turning the LNBF and no improvement. I have also tried mounting the LNBF in and out all the way, again no improvemnt, only made it worse, so I know I had it right. My signal level is >60 for both TP's, it's the quality level that differ between the 2 TP's. When it is working fine at night, the signal level and quality level are the same as day time.

is there any kind of towers near by such as cell phones or radar in the area that they may be turning the power down on in the evening and full power durning the day. maybe causing the interference try using something to block any signal into the side of the dish and see if the picture stablize.
