Re: [Elecraft_K3] K3/P3 video display on AM vs SSB

Is the P3 averaging?  That would cause the side band energy to look like it is low. And many ham stations don't maintain 100% modulation on peaks consistently.

You might try turning off averaging (assuming it's on) and see how it looks.

I have noticed a difference in the modulation sidebands on the P3 of RF waveforms on SSB and on AM.  On SSB either L or U the modulation display on the P3 is very close to the 6 dB down from where the carrier would be from Tune position.  But, on AM amateur or BC the sideband energy is NEVER 6 dB down?????? More often the major energy is 20+ dB down from the carrier.  Comments appreciated.....
