0 = standard operation (DX)
1 = forced FM RF AGC attenuation (LOCAL)

0 = keyed AGC off
1 = keyed AGC on; the AGC start level is shifted to a value 10 dB
above the standard AGC start level, when the level voltage of the
wanted RF signal is below the threshold level voltage for
narrow-band AGC
0 = cascode RF AGC active, PIN diode AGC active
1 = cascode RF AGC disabled, PIN diode AGC active
