I'm again responding with the standard disclaimer of not being an ARRL
adjudicator. However...I am the author of the HamIM strategy so...here goes...

"Ok, some people have already made the assumption that rovers can use
"full blown APRS", i.e. the network on 144.39 with all of its glorious
features
such as digipeaters and internet gateways. So how do you tell a contest rover
from a few
thousand other mobiles? They are only allowed callsign and position. Unless
they use
an SSID of -R, for rover, you can't pick them out."
*** In the early days of APRS, I lobbied Bob B. for a rover symbol. He agreed
and we now have a "Little Puppy"...a Rover! Launch your APRS frames with a
"to-call" of GPSLP and you will show up on everyone's maps as a Rover (puppy).
"The rovers are still running APRS and cannot use HamIM to it's full extent.
They are only allowed callsign and position, nor can they use digipeaters or
internet gatways
because the premise of no digipeats and no gateways is what got HamIM past the
ARRL contest
desk to begin with..."
*** There's the rub. The rules say that APRS is now approved. APRS uses
digipeaters and Internet. Use digipeaters, if you are a Rover or the Internet
as a Multi-op (the only two classes that are approved for APRS in ARRL
contests)! However...you are right about not having HamIM functionality
(ability to keyboard message) because the rules are specific to say that Rovers
may TX only their call sign and position and Multi-ops may only RX (including
Internet). No other operator use of APRS is approved.
