The only problem with the idea of a "portable" station is that with P3D that
will likely not be possible.  You will need gain antennas both to hear the
bird and work into it.  The bird will have an apogee of about 43,000 KM (
~35,000 miles).  At that distance, a portable station will not work.

Let's be realistic about this folks.  Working P3D at 43,000 KM is far
different than working UO-14 at 900 KM.  BIG DIFFERENCE.
