[MiQP-Mail] APRS ?

For the purpose of this response, RF-ONLY = 144.39, unconnected packets.

APRS [in the truer sense, all via unconnected / nonconfirmed RF packets]
would be interesting, and would indeed really help determine coverage /
lack thereof of the packet network.   APRS via your cell provider, well,
that's a no brainer.   Pretty much every position "spot" is guaranteed with
cell.   Depending upon where you are, 0 to less than 100% is your coverage
guarantee on RF.

One could suggest that RF-Only APRS might not be as useful as one would
like if one doesn't have a decent RF APRS setup and doesn't have good
coverage by digis and iGates -- and that it shouldn't be considered
self-spotting since it isn't as reliable.   Conversely, one could suggest
that having your position sent into the APRS network via your cell phone,
by virtue of its superior reliability, means that you should be punished
into some other operating category :)   All the mobile chasers [if they
know to go to one of the APRS webs like aprs.fi] certainly would be on you
like flies on doodoo as soon as you hit the county line, like clockwork.

I'm with Randy though -- if you aren't adding you band/mode in the comment
field, there is no way in the world it should be considered
"self_spotting".   Sure, people who are savvy can determine when you've
reached a new county [or are about to].   But they don't know what
band/mode you are operating.  Gotta have band/mode/time for it to be
considered a spot in my book.

Knowing how lacking Ohio is for APRS coverage (most of Ohio at least), I
hope to see as many Michigan marauders send [at least] position reports to
APRS, via 2m or cell.   It'd be real fun for some of us to watch the
progress as you meander across MI.  If you're bold enough to send a valid
spot with band/mode without concern that you might get docked, that'd be
even more of a hoot
