Reference frequency calibration on RT82

It so happens that my RT82 has a shift of reference frequency (at 144mHz -500Hz, at 70cm already more than 1kHz). When working in analog modes it is not a problem, but when using dmr (especially hotspot) it is already a problem. So far I solve the problem by introducing frequency correction on rt82.
In CPS the calibration tab is inactive.

CPS calibration tab only reads and writes the data file for the STM32 based radios.
It only displays the data for the GD77 type radios , including RD5R
You can calibrate the frequency in the firmware
