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…
I’m going to be playing about with and SDR dongle a lot, so I think it only fair to describe it.
I was playing about making audio cables to connect my cheap Baofeng to my PC. To test the recieve cable, I took a walk with the other Baofeng, and an Android App called SSTV Encoder.
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.

The nanoVNA is a bit of cheap kit that anyone with an interest in radio should own. I got mine from Amazon for £44.98.
If you are going to be starting down the long and rocky road to becoming ans Amateur Radio Operator in the UK, then really you need to buy some books.

My stupid antenna project started life as a 2M Project kit from Hamtronics. You can buy one if you go to their site.
Note: I have been informed that my information on GB3ZI is out of date. I will update this post once I know more.
Since I passed my Amateur Radio Foundation Exam a couple of months ago – mainly thanks to the excellent course run by Essex Ham (yes, I am aware that I live quite a way from Essex, but that does not matter) – I’ve been using the two local repeaters:
Currently my Amateur Radio transmitters and recievers are Baofeng UV-5Rs.
