Description
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
Local or distance. If LODX = 0, then distance mode is on. If LODX = 1,
then local mode is on.
FM mixer image rejection. If FMINJ = 0, then low injection. If
FMINJ = 1, then high injection.
This bit is not used and should be set to logic 0.
AGC switch. If AGCSW = 0, then AM AGC in FM mode and FM AGC in
AM mode is off. If AGCSW = 1, then AM AGC PIN diode drive is active in
FM mode and FM AGC PIN diode drive is active in AM mode.
FM mixer gain. If MIXGAIN = 0, then the FM mixer gain is nominal. If
MIXGAIN = 1, then the FM mixer gain is +6 dB.
