As I remember from years ago the portable after the call sign should be used 
when a person is not at the home location.  I would think that portable 
would be used while you are setup at a park and the mobile would be used 
when actually moving.  Just my thoughts on the subject.

Subject: Question about proper call designator for RV HF operation


Hi, all.

I struggle with the following question at the beginning of every camping
season.

What is the proper way for me to identify myself when operating HF in the
RV?  Does the answer to this question depend on whether I'm just having a
normal QSO, checking into a net, or working a contest?

Putting a portable designator at the end of my call seems to make sense,
since I am not at my home station.  However, I usually  run my station via
commercial  AC power, except on those rare occasions when I want to give our
generator a work-out.

Any thoughts on this would be appreciated.
