====== Using Digital Modes with the Yaesu FT-991a ======
The FT-991 has two microphones: the front microphone and a rear (data) microphone. I have seen others on the web describe how you have to change menu settings each time you change from SSB to a digital mode so that the microphone will change from the front to the rear.\\ \\ 
Using the menu settings found [[ft-991amenusettings_n7tms|here]], you can switch seemlessly between SSB, FM and digital modes without having to change the menu settings each time. 

With the above settings, change modes like you normally would.
===== From SSB to DATA-USB =====
  - In USB, the mode indicator in the upper-left corner of the display (next to the frequency) will show ''USB''.
  - Push the ''MODE'' button.
  - Select ''DATA-USB'' on the touch screen.
  - The mode indicator will now show ''D-U'' and the rear microphone will be selected.

===== From "any mode" to digital FM =====
  - Push the ''MODE'' button.
  - Select ''DATA-FM'' on the touch screen.
  - The mode indicator will now show ''D-F'' and the rear microphone will be selected.
