[SD-User] Mode Switching Problem.

[brian coyne]

I use a Kenwood TS570 tcvr with the MK!! Keyer running Sd V 17.33 with rig control and Winkey enabled.

In recent weeks the rig has spasmodically been changing from cw to usb mode, sometimes in the middle of a transmission and other times when the rig has been idling for a while.

I have disabled rig control and  the problem disappears.

Are there any suggestions as to the likely cause and how i can fix it?
