Well, we have a slight conflict Houston! I found the ARRL Operating
Manual - 9th Edition, and it has the same list as my 1977 Handbook, So
if we want to invite only the named station to transmit, we should send
a left-hand parenthesis symbol - Yes, the same operating manual lists
that too! Interesting.
