[Yaesu] FT-757GX Sudden Drift

[Federico J. Baldi LU4HKN]

And then make them a "thermal cicle" with a "hair-dryer", covering
from de air flux the cristal with your fingers.

This is because the trimmers may also have humidity.

I've solved something like this on my ft-747gx, 
using LU8EYW method + "hair-dryer".

73, fede.
