I have wondered the same about RTTY calls, if some characters are easier for
the software to copy than others. As someone who used to have a J in their
call, it often was changed to India on phone, not sure how that happened as to
me they don't sound much alike, other than they both have 3 syllables. The
last letter C often gets switched to K on CW and the first C often gets
switched to G on phone.
I am sure the perfect call is out there, I just havent found it yet
