Previous picture shows input power 5.5W, output power 366W. Power gain from input to
output of the PA was 18.2 dB. When operation mode of the PA was changed from CW to
SSB, output power increased (TCVR output power remained the same). This is because the
operation class of PA was changed from class C to class AB.
