I am running APSRdroid on my mobile phone (as PC5E-5, not very often) and send my location when working my PD785G (as PC5E-7), you can see where I'm at here. If you see a map of Helsinki, there was no location report from my device for too long.

Well, most of the time my location on my mobile phone is only triangulated using the mobile phone network, no GPS (drains the battery even more quickly), so it's bound to be off by some distance at times. =8-) My PD785G is accurate to some meters though. ;)
