m2000c bug

[bomberns127]

hello, i have created a few missions for the m2000c, i then open dcs, go to missions, choose the saved mission, and after the initial load i then press fly i get 'mission cannot be saved due to errors'
along with 'enfield 3' then' invalid frequency 124 mhz'
i then created a mission for the su27 and it went through no issues

I've had something similar, but not with m2000C. You can add your info to the Issue #637
