Indicates the RF output power in watts.
Indicates the VSWR on the transmission
line.
Indicates the ALC level. The ALC circuit
begins to activate when the RF output
power reaches a preset level.
Indicates the compression level when
the speech compressor is in use.
Indicates the drain current of the final
amplifier MOSFETs.
Indicates the drain terminal voltage of
the final amplifier MOSFETs.
