[Elecraft] K2 Power indication, CW vs SSB question

Wed May 7 13:20:02 2003

I aligned my radio and calibrated the output power meter using my
IFR1200S....I found that it reads actual carrier power in CW and when
watching SSB signals, it is showing PEP power.  So 5 watts is 5 watts on CW
and 5 watts is 5 watts PEP on SSB.
