That's in degrees.  The APRS format is DDMM.mmN/DDDMM.mmW in degrees and

;FD-FRRL  *111111z4186.44N/-88428.97W;147.210MHz W9NE-8A

Either one.

No, not if you are going to use the LTEXT.  The combination of the 4 LTexts
and the BTEXT gives a KPC-3 the abilty to keep 5 objects on the air.  Please
see www.aprs.org/localinfo.html

But again, except at FD, we do not want long term objects originated by
anything other than the local DIGI where it can do them DIRECT (no hops) and
once every 10 minutes, because only the digi can tell when the cahnnel is
treuly clear.
