APRS TX allows licensed Ham Radio operators to beacon their position details to the APRS-IS network using the internet.

The following information is sent in each position packet:

* Latitude
* Longitude
* Speed
* Altitude
* Bearing
* Beacon message (22 characters max)
* APRS Symbol

Now includes messaging between APRS stations.

Within the app you will need to specify your Callsign and Passcode. Pass codes are only available to licensed Ham Radio operators.

Passcodes can be generated here:

Within the app you may change the following information:

* Callsign
* Passcode
* APRS-IS Server URL
* Beacon Message
* Beacon Time Interval
* APRS Symbol for choosing which icon will be displayed on APRS maps.

You may also use this app on iPad devices but a continuous location will be required, normally through GSM or WiFi.

Please note: This app uses the GPS feature of your device. Continued use of this app may drain the device battery sooner.

Please email if you have any feature requests or bug issues. If you leave feedback reporting an issue I have no way of communicating with you to resolve the issue.

Great real time tracking

I'm KE0NAZ- James - it works great on iPhone SE and there are multiple websites which allow realtime tracking . I wasn't so smart at first as to getting a passcode but if you google it , it is easy to do. I've been researching how to hook it up to portable hand held & have found multiple sources for that also. Very well done from a professional developer. Not a fly by night 'vape wear at all - I give it 10/10 . For .99 cents ? Can't beat it.
73's ! KE0NAZ was here ... 👍🏻

Very simple to use. And developer is quick with support if needed.

Works nicer then my python based APRS Tracker on my phone. Though it would be interesting if Smart Beaconing could be implemented. (Not just time based.) still 5 out of 5!
