Не беспокойтесь о плохом английском языке. (Do not worry about bad English.)
Try "copy and paste" to and from "Google Translate". While it may not be exactly correct, it often helps us to understand anyway.
In any case, your written English is better than that from many who normally speak it !
About your signal problems, I nearly always prefer setting all of my V70 and 75 transmitters to the older "RF1" as you will see from this discussion:

This is critical.
