LTE2600/DCS with RF hopping problem issue

[Handover24]

Hi all,
in our network we have a problem after we installed LTE on the same WRFU where we have DCS.
For RF hopping we are using frequencies that we can not use for the LTE spectrum...for example...830-860 are the forbidden and used by LTE but for RF hopping we use 800,820,825 ->870, and so on.
After the LTE has been installed and activated we see many dropped calls on DCS cells and interference in band 5.
As there is no HW fault and parameters are correct, I'm starting to think that during the hopping from 825 to 870 the TRXs passed to frequencies beetwen 830-860 used by LTE.
What do you think about my idea ?
Anyway if we deactivate LTE cell everything works well.
please share you knowledge and experiences.
Thanks in advance.

Just to be clearer in other places where DCS have baseband hopping nothing similar has been observed.

Ok Guys issue solved anyway the problem was the wrong MAIO .
