Ok so I have researched on line, a few ARRL books I have around as well as some other resources. I am stuck is there any list of how to use. or all of the uses of slash call sign uses? I know for canada they have some for what area they are in I have seen in USA where people /6/7/8 etc for the area they are mobile in I know /p is portable /QRP is LP what are the others, I'm sure I will hear what is "allowed by FCC and ARRL law" but I would also like some replies on common day use as well. For example If I go to Hawaii and bring a radio /P seems rather boring. what do I add in that case? What if I am away from home somewhere of significance like a storm site for emergency help. Or what if I am at some significant landmark? I have seen all these uses on the air in different uses. Is there a list anywhere? and please I would like best practice as well as common practice answers.
