Ok… Firstly, there are many guides to doing this already on the internet, but most of the use a Raspberry Pi. I’m not using one, for reasons that will be made clear later.

Secondly, I couldn’t find any one of the guides that did exactly what we wanted.

Before you read all this rubbish, it is important that to use it you will need an Amateur Radio License and Callsign, and and APRS-IS Passcode. If you don’t have them, then go and get them before continuing.

So, with that in mind…

On with the motley

Simple PC to Baofeng Audio Cables

This post is not about the the PC/Baofeng cable that is used for programming the radio. If you want one of those, then try Amazon.

This is about connecting the audio streams twixt the radio and a PC.

The basic mission is to take the Soundcard in/out from a PC and connect it to the Kenwood K2 connector that the Baofengs uses.

These cables are simple, and they work, but they may cause damage to either your PC or radio if used incorrectly. Much like a can of Coke.

If you are getting started with APRS, then the easiest was will be to do it on your Smartphone. This post is only about using Android phones, obviously. The clue is the “droid” part of APRSdroid.

NOTE: for this you WILL require an Amateur Radio License and Callsign. If you do not have a Callsign, then I suggest you just watch what is going on on the APRS.FI website.

So you’ve got that this isn’t about iPhones?
