James:?
These documents (Appendix 1 & 2, as I reecall, are useful in figuring how to enter your call sign and the canned messages for RTTY and CW. (I am strictly a CW ?op, so I can’t comment on SSB et al.)
In my version, it is not possible to send an S or a Z, a problem for W9ZSJ. I think the firmware is looping based on the assumption that letters may be grouped in 3’s, as on an old telephone or celll phone KB. But, there are two buttons there which have 4 characters. The extras are - guess what - de W9ZSJ.
I will be interested to see if the new release fixes this.
