APRS

 Just some random things that I had a hard time finding when researching how to set up APRS. Some of the things might seem pretty basic - if it doesn't apply to you, then ignore it!

  • APRS is designed primarily for Simplex in the US. You transmit your packet on 144.390MHz so that a local Digipeater (which also receives on 144.390MHz) receives your packet. It will then take it and re-transmit it to other Digipeaters based on your Digipath or to a local iGate.
  • Once it's received by a local iGate, it can then be translated and relayed to the internet and then show on sites like APRS.fi. 
  • If I didn't already have many of the pieces, I probably would have just spent my money on a radio that also had APRS built in or an APRS Terminal Node Connector (TNC) setup.
A lot of my questions were also answered on this Reddit Post.

Part 1: SMSGTE - Texting using your DMR/APRS Enabled Device - Starting from the Ground Up

Hello!  So.  As a precursor, this was inspired by my experience trying to set up my DMR Enabled radio to send SMS messages using the SMS Gateway Service. Please know: I am in no way associated with SMSGTE.org (other than a regular user). I just figured I'd document my process to provide another way for those interested to follow. This is using the AnyTone AT-D878UVII Plus, so it IS ABLE to receive messages to the radio. It is my understanding that the previous models do not support Rx APRS.  I do not have any other models of DMR radio, so I currently can't offer any kind of step by step on anything other than the AT-D878UVII - sorry! Not saying that won't change, but it's what I have to offer at the moment. That being said, I'll do my best to make it as broad and specific as possible? (I realize what I just said... lol) Important Links for this process: SKIP TO PART 2 - THE SMSGTE INSTRUCTIONS SMSGTE: https://smsgte.org/ Brandmeister: https://brandmeister.network/ A...
