(1) Modulation: (FM/FM-HD/HD) This will change the bias mode of the PA module.
(2) Operation Mode: (BOOST AMP/STAND ALONE TX) The difference between
the boost amp and the stand alone are limits on power and reflected power.
(3) TX Type: (MINI-HD/QUEST/Z_4_6_8_HD/Z_12_16_HD/Z_HD_DUAL/
Z_2_CD/ Z_3_5_CD/Z_7_10_CD/Z_CD_DUAL/LP_HT/MP_HT/HT_20_25/
HT_30_35_B/ HT_30_35_A/HTD_60_70/PT_2_4_5/PT_8_10/CUSTOMIZED).
