Steve,
I'm just writing to help you put the / sign in parentheses that are different from the usual structure (meaning occasional call signs).
For example, I called station EA8AAH/5 and I thought from its transmission frequency that it answered me, because I saw
HA3H <...> -03.
? I deleted 73 from the GRID (CQed without Grid) and answered.
This was literally made blind. Here is a picture of it.
