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.
