Having used a Serial Sound Card Interface between the computer and radio for many years I was looking for something better. The first option was to buy a Signalink Interface. Current price $129.95 (R1719.34) without postal and import taxes. This was not an option at all. I decided to search the Internet and found several units that work with transistors. I was looking for something that would incorporate an Arduino Nano unit. Well I found a complete write-up by an Old Techie. I am not going to go into detail here other than to post images of the project with a reference and acknowledgement at the end of the post.
Starting on the Veroboard!
Making my own cabinet with aluminium.
Veroboard – I hate to work with it!
Just look at all those wires. A real mess!
Front and Back.
Structural completion and ready for smoke test!
Still a lot of wires but more tidier than before!

I can tell all that it is working flawlessly just as good as the Signalink if not better. Now why write about this project on the AREDN: Mossel Bay Mesh Network. I will be using this interface with Winlink 2000 and an amateur radio transceiver to eventually establish a VHF Gateway / HF Winmore Gateway Station.
Final cost for this Radio Interface Project = $17 (R224.67) A big difference in the end.
