It *sounds like* you are still in AFSK A and not DATA A. By default
AFSK A has a narrow audio filter on the input of the modulator process

I worked the RTTY contest yesterday using AFSK with N1MM. All worked
fine and I shut everything down when I was done. Today I tried to
operate FT8 but I can not get any power output.

Sam,
You are doing it right.
DATA A mode is like SSB with the following exceptions:
1) TX EQ is disabled in DATA A mode
2) Audio compression is disabled in DATA A mode.
3) one can set the audio input to LINE IN for DATA A mode - no need to
change it from MIC audio when using data modes.
Eithe
You can use DATA-A to do LSB too. I do this when I set up the KX3 for packet
radio, because it places the LO just nicely so I can also monitor the local CW
calling channel and my club's SSB frequency, using a separate SDR app on my PC.

The K3 uses up-conversion 6 m, which inverts the sidebands. It should stay in

I know DATA A sets CMP=0, and I think it sets MIC+LIN=OFF

DATA A and AFSK A do not automatically set MIC+LIN=OFF. However,

Hi Paul,
All I know is the RX EQ is still enabled in data/cw so my guess is the TX EQ
remains enabled as well.
Shouldn't be the case, because RX EQ has a negative effect on Spot and Text

For convenience, I have generated a number of macros under the HRD
CAT command facility. I assigned them to buttons on the HRD front
panel. I have macros for TX EQ & RX EQ for CW & SSB.
For easy identification, part of the macro displays the name on
the K3 LCD bottom line.
E.g.
TX SSB1
AI0;K31;
You could use the following macro till this gets sorted in the firmware:
AI0;K31;MN009;SWT53;MN255;K30;
A similar macro could replace your TX SSB equaliser settings at the touch of
a button. There are more details on a previous posting for RX Equaliser on
this forum.

What are the benefits of using Data-A mode for psk31 as opposed to standard USB.
The manual p29, mentions that DATA mode offers several benefits not available

other than automatically setting CMP to 0, I can't see much else happening.
