## meanwhile, the Elecraft K3 is a lousy -29 db PEP (IMD3) at 100 watts pep out. The ANAN 7000 / 8000 is a lousy -30 db pep ( IMD3 ) with pure signal disconnected. On most of these SS xcvrs , when power output is reduced,
the IMD drops like a rock. A TS-850 is -30 db PEP when run at max rated 100 watts pep output..... which drops a whole bunch when run at just 85 watts pep out..... which then drops through the floor when run at 50 watts pep out.
I see the same thing on my FT-1000D and also my FT-1000MP-MKV.
## IMO, I see nothing wrong with referencing IMD to pep output. S meters are all peak reading devices, whether a panel meter or peak reading leds. If Joe ham is say 30 db over S9 on ssb mode,
but only S9, when tuned off freq by XX khz, then Joe hams IMD is down 30 db...end of story. We dont say Joe hams splatter is 24 db down from one tone of a 2 tone signal.
