6 Khz Filter Use in Data A Mode

AL7CR
I wish to be able to recieve and transmit using the WSJT-X  JT65 + JT-9
mode.  I know from archived posts on this subject that my recieve
bandwidth using a 6 Khz filter in Data-A will be approximately 300 -
4200.  The question is can I also transmit in this range in Data A?  I
do not want to buy the filter unless this is possible.  The filter setup
utility appears to allow this however the Elecraft and Cady manuals
state in many places that you must transmit SSB through either the 2.7
or 2.8  filter.  Perhaps the ESSB feature allows this operation but it
is not clear if this functions in Data A or if it is required in that
mode.

No.  ESSB is not active in DATA A - transmit bandwidth is limited
to approximately 300 - 2500 Hz by the DSP.

However, if you use WSJT-X in "Split" mode, WSJT-X will automatically
offset VFO B and adjust the tones to keep the transmitted audio between
1500 and 2000 Hz (for maximum rejection of distortion and harmonics)
through the full 300 - 4300 Hz receive bandpass (both JT65A and JT9).
