Data Mode

[W4GRJ]

I use an external soundcard/interface "Navigator". My main use is passing traffic on MARS via MT-63 and MFSK-16. I just leave the radio in USB and set the mode freq via HRD DM-780. Everything works great, my question .... is there any advantage to switching the radio to Data Mode?

Data Mode turns off the TX Equalizer and front panel mic feed.  It  also
remembers your filter setting.

Jack,

The advantage to using DATA A mode is that the compression is set to
zero and the Equalization is turned off.  If you are also using SSB and
have compression set for SSB and/or are using equalization for normal
(speech) SSB mode, then it will be an advantage for you to use DATA A
instead of SSB.  If you never use a microphone with the K3, then you
will find no difference.
