Further to what I wrote, I have just noted that the power output in DATA A still varies though only by about 2dB across the passband even when the audio input is increased to drive 4-5 bars of "ALC".
In SSB mode, with the audio level adjusted to no more than 2 bars of ALC, and CMP reduced to zero, there is no significant change in TX power output across the whole passband. Furthermore, the power is correctly set to the level specified on the PWR control. Significantly, I observed no difference in IMD measured using my KK7UQ IMD meter whether using DATA mode with no ALC, or SSB with just enough ALC to control variations across the filter passband. The IMD was -29dB in both cases. I believe that when the K3 was released a year ago, the DATA A mode was identical in behavior to SSB except that it disabled CMP and allowed a different selection of input source. If Elecraft would revert to that functionality then I think everyone would be happy. I know I would. (It would actually be nice if DATA A disabled RX EQ and TX EQ as well.) ----- Julian, G4ILO.
