Interference? A newbie need help, please

[drchao]

I have a cw 800 receiver and two dishes. I can have SAT#1 in good Q & S (>80) in dish one if hocked directly to receiver. And also another SAT#2 from dish two if hocked directly. When I try to get both using the supplied cw-41 diseqc switch, I still can get SAT#1 if I stick on it. But after watch any channel in the SAT#2 (second dish) and switch back to SAT#1, only get 'weak signal'(Q=0, S<50). The channels in SAT#2 are still ok in the meantime (Q, S>80). I have grounded the dished and diseqc, but no work. The only way to have SAT#1 back is to hard reboot.

Could this be a problem with my lnb? Diseqc? or just the interference between the two dishes? How to solve? Can I set two different LNB freqs in two LNB when using diseqc?

The seetings, (Only the two LNB freq are different)
for SAT#1, Diseqc number: LNB1, LNB Freq: 10750, LNB type: Normal, 22khz: off, Legacy SW: off
for SAT#2, Diseqc number: LNB2, LNB Freq: 11250, LNB type: Normal, 22khz: off, Legacy SW: off

The length of Rg6 cables are 6 feet each from dishes to diseqc and 35 feet from diseqc to receiver (including a 8" flat Rg6 cable to pass through the window).

Thanks

Which two satellites?

If the diseqc switch is a 4 port switch, try using port 1 and port 4.

Thank you for your helping. No luck at all. I found the 11250 Freq LNB can connect to any port but the 10750 freq LNB can only work on port 1. If I connect the 10750 freq LNB (SAT#1) to other port of my diseqc except port 1, the q=0 and s<30. So, I connect 11250 Freq LNB (SAT#2) to port 4 but the result is same.
