Ya I have 64 turned off on all of them.


I thought maybe one of the UE's, which was about Mid Span between the two sectors, was jumping somehow which is why I was looking to Freq lock it but that's not it.


A couple nights ago I reset the eNB to factory and configured to SplitMode2x2 using the Frequency of RAN 2&3 (the problem side) and both problem UE's connected, but I know from prior experience that config is not stable with UE's in the space between the sectors.


So I then set it back to SplitModef1f2 and those two could not connect.


Both of the UE die at this point:

I occasionally see this in the log

and/or this

I haven't seen this, but also not running split mode FWIW.

Still haven't gotten 8Ks to work in QAM64 uplink.
