[aprssig] APRS Local Info Initiative

[Keith VE7GDH]

I was giving someone a hand with the IRLP APRS status script on
their node and commented that the frequency wasn't entered
correctly for users of the D72/D710/FTM350 (does the VX-8GR also
do this?) to use the tune/QSY buttons. While trying to make
suggestions, I noticed that the node is on a UHF frequency with a
minus offset. Do these radios automatically handle the offset or
should the offset direction be included in the object?

The following pages are related, but I couldn't find a mention of
offset / shift direction.

Shift is mentioned on the following page, but not how it is
implemented. Going by the original IRLP APRS status
script, I believe it should be after the tone. Is this correct?
Should it be blank or an S for simplex?

Is it assumed that the radio will automatically use the correct
offset? If so, will it do this when there's an oddball frequency
e.g. on 70cm with a minus offset? Or is the operation dependant
on the object showing the actual shift direction?
