[Elecraft] KX3 CAT commands for DVR

[Chris Tate - N6WM]

In the KX3 I am looking for a functional way to key the dvr from a contest logger via CAT commands.

For instance to trigger the M1 dvr selection this string is sent and it actuates that DVR selection
{CATA1ASC SWT21;}{CATA2ASC SWT21;}

Assuming the KX3 SWT21 is different than the K3, what would the appropriate SWT be for the KX3 DVR?

I am searching the reference manual and not finding it..  any help would be appreciated.

Thanks
