This ^^^^ is bad, you have something wrong with your feeds. They're probably over amp'd and your leaking RF like crazy. Go back to basics, put the single unsplit and unamped feed into a single 115 and get that working reliably. Then, split (or amp) and try the second 115. Try to work out what's causing BER to be > 0 and fix that first. Personally, I wouldn't add the 250/350 back into the system until I had both 115's running flawlessly with 0 BER and 0 UNC. Chances are, the 250/350 will work correctly after this - unless the drivers really do have a DMA issue. It's too early to say given the BER/UNC issues you're seeing though. - Steve
