All APRS packets are defined by their first byte.  The OBJECT begins with a semicolon.

;442.175MI*111111z4258.14N/08539.91WrT103.5 Dtwn

For what it is worth, the standard for Tone is shortened to only 4 bytes "T103".  Thre is no need to waste two extra bytes for tenths of a Hz, since the tones are all standardized.  We need people to follow this standard so that their objects can be parsed properly.  The proper way to display a tone of say 88 HZ is T088...
