MotoTRBO SL4000/SL4010/SL7550 Deaf Fix - low signal low RSSI

How to fix an SL4000/SL4010 that has suddenly become a bit deaf on RX and does not seem to work as good as it used to. Even on TX.

I discovered this fault today. I like to get credit for things I find, like the D1700 Tetra conversion solution.

This is a quick fix and here I show you all how to fix it. FOR FREE! No software or downloads required.

All you need is: a T5 and T6 screwdriver!
