I need the CAT codes for my FT-991 so I can use the radio with WSPR.
Surely there must be someone at Yaesu who has this information.

The last Yaesu rig I bought was an FT-817nd which had the CAT codes in the back of its manual.
But the FT-991 manual does not include the CAT codes.

The FT-991 advertising copy talks about digital mode. Not too useful without the CAT codes.
