ARGH!!  You are right.  OK, here is the receommended new format
that will work.  We will send the objects in 3rd party format so
that the PHG will work correctly.

BT }146.670->APOBJ:4612.74N/06320.46WrPHG8560 IRLP2030 VE1CRA

These will all be sent to the APOBJ TOCALL and we can use that
as the universal indicator of a permanent object.

Ah, but only on FINDU and other global collectors of data.  The
purpose of these local objects is locally only.  And there would
never be two repeaters on the same frequency in the same area.
The fix is for FINDU and other collectors of global data to
recognize that the TOCALL of APOBJ specifies a permanent object
that should not be overwirtten by anyone except the original
sender.

Thanks for the feedback.  Ill fix the other docs.  Besides, this
format is slightly shorteer anyway...
