    I recently installed a SWM8 multiswitch. I do zero diplexing. I have 2 hr21's and 2 D11-100's. I connected the D11's to the legacy outputs of the multiswitch and used the SWM outputs for the HRs. PI is connected into SWM1 on the switch. All of my boxes are functioning correctly except for this one D11-100. It keeps getting pixelation. I checked the signal levels for 101deg and they are all in the 90's - 100. However when I go to check individual transponders it shows full signal level . IE 92% for transponder 1, then it goes to zero, then back to 91 or 92 then back to zero. It is doing this constantly. A reset of the box doesn't fix the issue.

    I am assuming it is either an issue with the box itself, (I thought the D11 series boxes rarely had issues) or a bad legacy output on the SWM8 or lastly a cable that has gone bad.

    Has anyone else had this issue?

    My next step in resolving the issue will be to take the other D11box and bring it into the same room with the other d11. To see if it is the box or the SWM8. Then Switch the Legacy 1 cable to the legacy 3 port on the SWM. And lastly, which sucks the most, replace the RG6 run. :confused:

    The first thing I would do is swap the connections on the legacy ports at the SWM8 to see if the problem follows the receiver or the port. If it follows the port (i.e. now the other receiver has the problem), then it very will could be a defective SWM8. If it follows the receiver, then it's either the receiver itself or cabling. At that point, you'd want to swap receivers to see if it follows the IRD or cable and then you'll know. My money is on a cabling issue. make sure you check all your fittings for clean insulation around the center conductor - i.e. no stray braiding from the shielding is in there.

    I always check my cable ends. There are no shorts in my system. Anywho it turned out to be the box. When I switched them out the second d11 worked just fine. Plugged the 'bad' one back in and it worked fine again. My guess is it just needed to be 'reset / power cycled'. We will see if the symptoms return.

    Thanks for the input.

    Well, dang - I'd have lost money on that bet! But I'm glad you got it working. :)

    Ya didn't try my personal fav. Get a RBH* and just show that sucker to the box that isn't doing the job!
