Your Up power levels are all at the max 51dBmV - and so will be struggling. There are a lot of RS errors too - SH2 always shows a few but lets start from 0. Can you press the reset counter buttons and also do a pinhole reset to force the Up channels to reconnect and see if the power levels drop down
