I think that the problems is on parameters of RF hopping.
You have set MAIO step = 1 and this cause interference problems, because you are using adjacent hopping frequencies for the TRX-s of the same cell.
Are you using more than one hopping trx per cell? if yes then MAIO step should equal or greater than 2.
With the MAIO Step parameter you can use successive channel numbers within a
single cell. For example, with step value ‘2’ 400kHz channel separation is achieved.
Hope I could help
