I use SARTrack and have a similar problem with a friend of mine.? He uses an Apple Phone and not sure which APRS app is used on Apple phones.? All I know he shows up on .fi but not on my APRS map and my station is an i-Gate.? I wrote it off as a problem with whatever Apple APRS App he is using.? Just pointing this out that it might not be a program problem but possibly and App problem.
