In the original file the line reads
ModeUSB=MD2; Puts radio into upper sideband.
ModeUSB_D=MD9; This puts the radio into FSK Reverse,
Here is the corrected commands
[Kenwood TS-590]
ModeUSB=MD2; Puts radio into upper sideband.
ModeUSB_D=DA1; Puts radio into Data mode (filter and AGC settings for AFSK)
Thank you. I will update the file and upload a new version
