I was also curious about this question, and I researched it using N76, then tried to implement a solution based on HT.
Connect the N76 to the HT on your Android phone, and to avoid interference, switch to a different, unused frequency, for example, 438.100 MHz.
In the top-right corner of the HT APP, tap the three dots and then enter "Settings". Configure the following settings separately:
Settings-ID signaling- The very bottomBSS/APRS routing,TTL、Maximum forwarding countTwo set to 2
Settings-APRS Configuration:
Log inEnter your own call sign password, for exampleBG4IJK-1
- Turn on
IGate gatewayThe switch on the right, then turn it on.Radio to Internetthe switch
Share location-IconTo make it easier to understand, find an icon for a cell tower./r
After adjusting, switch to another radio that can transmit APRS, setting the frequency to 438.1 MHz and the call sign.BG4IJK-7Once the icon of the person, and other devices have successfully located (placed by the window or outdoors), use it to send a beacon signal into the frequency. Then you can see that two have appeared on the APRS map.BG4IJKAdditionally, "Little Person" BG4IJK-7 reported through "Iron Tower" BG4IJK-1.
