Rich, I understand the original question, I was just trying to simplify things by explaining there is no need to switch modes. This is very convenient on the MARS nets which are USB and we quickly switch to MT63 for traffic.

The question is: Why doesn't RMS Express work properly in DATA A mode? This is precisely the kind of application that DATA A was intended for. 73, Rich VE3KI On 02/01/2012 7:53 AM, W4GRJ wrote: > I use RMS Express Winmor, DSM780& FlDigi MT63, Airmail Pactor and MIL110A, they all work perfect with the rig left in USB. > > Jack > W4GRJ / AFA4DG > > On Jan 2, 2012, at 3:43, Richard Ferch<ve3...@storm.ca> wrote: > >> W4GRJ wrote: >> >>> Just leave the K3 in USB, do not change to data mode.
