radio jacked up on CM 10 & 11 on SCH-T989 topic

What more can I say? ... That would be helpful anyways.

It started about CM 11(ending in 14) I have no voice or data service. The cell radio strength bars go from ful to 3g, to empty in a matter of seconds and then repeats, cycljn through full to nothing again .

I've tried flashing the ULVM6(I think) radio and no help.

Any suggestions would be greatly appreciated.

Thanks in advance!
