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 MOS-FETs.
Indicates the drain terminal voltage of
the final amplifier MOS-FETs.
