Crazy problem, from 3AM/CET till 10AM/CET I get perfect signal with prime focus dish.

Its an old Aluminum 2M Prime focus dish, it has 17 or more years. I have some Sharp LNB 0.6 or 0.7db/twin, with horn integrated for a prime focus dish.

This dish/LNB is connected to a Skystar 2 (ver 2.3) pc card and pointed to a:
Atlantic Bird 1/ 12.5° West./TP/Frequency: 11428 MHz/Polarization: Horizontal/30000
I have signal quality of 78% and 11db snr.

Problem is that something is happening at a time window from 10AM till 3:50AM,
because in a time window frame from a 3:50AM till 10AM a have perfect data reception after that I have problems..
What could be wrong, what is causing that in a specific time frame everything is good and in specific time frame everything is bad. How that can be possible?

Should I tried with some new LNBF like 0.2db or 0.3db mounted with LNBF collar for a prime focus.
Will I overcome this incompatibilities with this problem.
Will I had some LNB signal spiff if I use universal LNBF for offset dish on prime focus dish mounted with a LNBF collar.
And is it significant spiff comparing it with a gain from a new and better LNBF with 0.3db comparing it to a -0.6 or 0.7 LNB for a prime focus.

What should I do, I need help.

What is your signal quality at the time when you have bad data, i.e. is the satellite transmitting and are you receiving data? If you have good signal quality when you're not receiving data, then look at the computer software. Does the program have a menu item that limits the amount of connect time to a specific timeframe? Or has your distrubutor limited your time usage to a specific timeframe? Just need to gather some more information.

Have you tried any other frequencies on the satellite to see if this problem affects other channels on the satellite?

Several things could cause signal loss:

LNB is drifting off frequency during temperature changes- This can occur as a LNB ages. Try changing the LO frequency up or down 2 or 3 MHz when the system loses quality reading to see if siganl is reaquired.

Terrestrial RF interference- Several years ago my mother's C-band system would go out during certain times of the day when aimed in a certain direction. We traced the problem back to a faulty power pole transformer that would spew RF under certain load levels ...
