NSM-3 SB-050

- Value for two resistors (R205, R206) has been changed smaller

- To reduce phase error capacitor C837 has been added

- To decrease power AM-ripple and give more marginal to modulation

spectrum value for two capacitors (C540, C541) has been changed
smaller

- Value for one capacitor (C803) and resistor (R802) has been changed to
improve TX spectrum and phase error

Note 1: No changes are needed for phones coming to the service.
Note 2: Only MCU SW version 5.27 or newer can be used with this 1905
