That was indeed the case, I had NMEA on COM 4. Again (at the risk of showing my utter ignorance), it is impossible for APRSISCE to send the data the radio AND receive the GPS information from the D72. That tells me, by inference, is that when I am beaconing, the lat /long data is not from the internal GPS in the D72, but iis derived from where the ME station is loccated, as directed by me.
> > I am using the the interal GPS of the D72; there is no other GPS involved. As I have said over and over again, this set up weas working fine for the last two days. When I restarted the system, nothing was happening. After playinng silly bugger with it for a while (about 3 hours, it still does not work. It kept dinging evey 5 seconds or so. A could of times, a beacon did get out, but it shows my poition in the middle of Ottawa, not in Roc kland. On the other hand, the APRSISCE map show me in downtown Montreal. So there you have it. Finland shows me I am in the middle of Ottawa, APRSISCE shows me that I am in Montral and my D72, right beside me say I am at my home location in Rocklan., Not to be too obttuse, which one do I believe?

Yes, I was able to do that.

I unchecked that box, then I hit the Transmit tab in APRSISCE and went to aprs.fi. Finland agreed (perhaps to be more precise, Helsinki?).

Indeed it did.

OK. I went into my directory and found an APRSISCE file that said it is an XML document, so I will e-mail it to you.

So, since I cannot confiure the APRSISCE data going to the radio and have it read the internal GPS, is there any way in which I can pick-up my laptop, and the D72 and hop in the car and have it track me on the screen using the D72 as my GPS? Or, is the only way to plot ME on the APRISCE screen while I am out and about is to "eyeball" my position so to speak? (Actually, I run a Garmin Zumo in my car and from time-to-time my Garmin oregon, so I can get their data, and acutally see where I am. Even by hitting the POS button on the D72m it currently shown my Maidenhead and Lat/Long. So it is not quite as bleak as one might think at first).
By the way, what are the chances of getting an MGRS (miloitary grid refernce system) readout. It would be handy to get a Grid Reference so that it can be easily plotted on a topo map, usually used by operational centres, at least up here in Canada.
Anyways, let me send you that file., and thanks for your patience. I am sure that you are justas annoyed as I was wondering what the heck I was doing...
