The range seems ro have recovered, but has been more glitchy. The dip in range seems to correlate with noise seem in our DARM BLRMS between 10-60Hz and maybe a little into the 60-100Hz band as well. This makes me think that its the the smae noise that we've been seeing. I don't see anything in the 30-100mHz Z SEI BLRMS though.
