Keyed FM AGC. If KAGC = 0, then keyed FM AGC is off. If KAGC = 1, then keyed
FM AGC is on.
Wideband AGC. These 2 bits set the start value of wideband AGC. For AM,
see Table 18 and for FM, see Table 19.

Local or distance. If LODX = 0, then distance mode is on. If LODX = 1, then local
mode is on.
Software programmable flag. If FLAG = 0, then flag output pin SWFLAG is HIGH.
If FLAG = 1, then flag output pin SWFLAG is LOW.
