Preferably the way to do this is to decode the mic-E including
the altitude and message coment field and then display the
packet with them merged togehter into the intended standard
APRS conversion:
=DDMM.hhN/DDDMM.hhW$CSE/SPD/D-700/M#/Enroute../A=000456
Where:
DDMM.hhN/DDDMM.hhW$ is the normal posit and Symbol
CSE/SPD is the standard course and speed
Next are 5 byte type: D-700, TH-D7, Mic-E, etc
Next two bytes are the position comment bits M0 to M7 or C1 to C6
The next 10 bytes are for the decoded version always padded to 10 bytes
/A=xxxxxx is the Altitude.
