* offset measurements made with a CMU200 RF tester:
*
* Psi_sta_inv: 3462
* Psi_st: 15
* Psi_st_32: 992326
* Psi_st_inv: 4328

* The following AFC slope number is the closest OsmocomBB-style afc_slope
* integer corresponding to these Psi numbers; the true value is somewhere
* between 454 and 455.

* This AFC slope setting is expected to be correct for both Openmoko and
