 ## Notes on APRSdroid
-APRSdroid support has been added by AIOC by implementing support for the fixed 22050 Hz sample rate that APRSdroid requires. 
+[APRSdroid](https://aprsdroid.org/) support has been added by AIOC by implementing support for the fixed 22050 Hz sample rate that APRSdroid requires. 
 It is important to notice, that the exact sample rate can not be achieved by the hardware, due to the 8 MHz crystal. 
 The actual sample rate used is 22052 Hz (which represents around 90 ppm of error). From my testing this does not seem to be a problem for APRS at all.
