How To Get GPS Data Out From My IC91AD ToThe Gateway

[George]

I can see that my IC91AD is receving GPS data from my external GPS unit.  However, I can not see that it gets to the gateway so that I can see it on APRS.if.  believe I have coded my 91 correct, ur,r1,r2, and mycall.  I have used the DPRS calculator, however, not sure which is the C1 sentence to use to put in "MV    *32" .

I would appreciate any help.  Thanks, George

This is the message that is sent when sending GPS.  In most radios, it is the C1 message.  It may also be called the GPS message.
