Ray,
I followed up the other day with a better description, hopefully you saw that,
but here's more thoughts:
You changed your statement from "use that data" to "use". They are two
different statements. A Rover beaconing on APRS but not looking up other
Rovers or fixed station locations with it, is different than an Unlimited Rover
using mobile data and/or other Internet/whatever spotting networks.
Rovers all may TRANSMIT APRS data, unless banned specifically for a category --
with the additional caveat that no Rover in a category where they're
one-band-at-a-time, may transmit with two radios simultaneously on the same
band.
In other words, look up the rules for your category about simultaneous use of
other bands and or one band and apply it just like you would if you had two SSB
radios side-by-side.
(e.g. Shut off your APRS tracker beacon whenever the rules for your category
say you have to... let it beacon a few times when you stop, but then shut it
down when operating, or when operating on the same band, depending on your
category. You'll want to do this anyway since it's going to desense the snot
out of your other receivers on that band anyway.)
Only UNLIMITED Rovers or Multi-Op stations may USE that data to find other
Rovers. A non-UNLIMITED Rover may not use APRS data to FIND another Rover and
point at them from a SPOTTING network ... but... they can use the data if they
DIRECTLY COPIED THE TRANSMISSION from the other Rover.
Clear as mud, or is that a better description?
Should it be simpler... yes. But it wasn't that long ago that APRS of any kind
from a Rover was "self-spotting" and there wasn't an UNLIMITED Class that could
USE the data.
It's not too hard to build a "truth table" or just a list of rules specific to
APRS... just go through the rules from start to finish, with a notepad, and
write down the rule numbers that apply to APRS and your category... then go
back and read those, and you'll have it right for your category/class of
station.
What type of Rover are you interested in operating?
