Keith, thanks for taking this on...

I think adding the hyphen between IRLP and 1148 shows up nicer
on the radios and also fills the full 9 byte field.  [IRLP-1148]
The S is not needed, assuming standard band-plan offsets.  Also,
the S then pushes the Tnnn to the right and out of place with
the standard format.  The reason for sticking to the new
standard is so that all software (including the new D710 radios)
can parse this tone and in the case of the radios, auto-tune to
this frequency and tone.  So the Tone has to be in the right
place. And be exactly Tnnn always. (leading zero and no tenths).

Further the Range format for range has to be Rxxm or Rxxk.  This
is so that the combination of FREQ, TONE and RANGE all fit
nicely on the 10x10 displays of all the APRS radios.

Ill go try to find those missing links and photos.  Thanks.  Bob
