If you're sitting in your car parked in your driveway operating, is that considered mobile? If you have a temporary antenna at a campsite running off the campsite's 120v power, is that fixed or portable? If you're in your car with a coax going to a dipole hanging from trees, is that mobile or portable?

No such rule exists that would (or could) describe each and every operating position; at rest, in motion, etc. So, it's sort of what makes you warm and fuzzy.

As a general rule, a fixed station is
just what it says, a portable station may be
moved from place to place, but not operated in
route and a mobile station is one that can operate
in motion or stopped.

An Aeronatical Mobile is one outside the
airspace of any country and a Maritime mobile
is one that is not in the territorial waters
of any country.

Hope that helps.

I should have added that a fixed station
is also called a Land Station.

We joke that traffic is so bad around Washington, DC and surrounding areas that we are MORTABLE. Not really mobile but not really portable. Rig and person in a car but moving at walking speed.

HI HI!!

The other day the traffic was so bad that under the old regulations I would have had to notify the FCC of a temporary address change :-)

>>If you're sitting in your car parked in your driveway operating, is that considered mobile?<<

Using the mobile antenna, I'd sign as mobile regardless.  


>>If you have a temporary antenna at a campsite running off the campsite's 120v power, is that fixed or portable?<<

I'd call it portable, since someone trying to find the location wouldn't reasonably be expected to find a permanent installation there.  


>>If you're in your car with a coax going to a dipole hanging from trees, is that mobile or portable?<<

You are in a mobile, so I'd sign mobile.  

It is typical in a QSO to tell the antenna in use, that's the time for clarification if any.

On one hand, it doesn't really matter what you call it - there is no
legal requirement to identify in a particular manner.

But, generally, if your station is capable of being operated while in motion
(even if it is presently at rest) then it is a mobile station.  If it is at a
relatively permanent location it would be fixed.  And if it is being used
away from a regular "fixed" location (set up temporarily) then it would
be portable.  (The old definition was that any operation away from the
location shown on your license was identified as "portable", even if it
was on a long-term basis.  While that legal definition is no longer used,
I might still sign "WB6BYU portable 7" to indicate I am not operating
from the 6th call area, even if it has been 15 years since I moved.)

Using these definitions, a parked car would be mobile if it is using an
antenna capable of being used in motion, but portable if your antenna
is hanging between two trees.  If I set up my HF rig in a campsite or
park I'd call that portable, regardless of the source of power.  If I am out
at a vacation home for 2 weeks (or 3 months) and operate from there,
I'd probably still call it "portable", depending on how much work it took
to set up the station.   It really would depend on the context.


But there is no official legal definition for these terms, or any requirement
that you identify differently depending on your situation.  (Some
contests or awards may have specific requirements - such as what
constitutes a mobile station for Field Day, but those aren't necessarily
consistent either.)

Well I look at it as what raido/antenna combo I happen to be using.  When at home with my HT if I have the rubber ducky on there I call out "KE5OFO Portable", In the car with the mag mount "Mobile" and at home with the mag mount on the ground plane sheet I don't make any distinctions.
