Jeff, WB5WAJ was looking into uses for his TinyTrak4 and came across this article by N3LUD describing how to use it with Winlink Express. Jeff has successfully used this setup for Packet Winlink with his Yaesu 7800 and says “The install is very straight forward. The radio has a 6 pin data jack. The cable connects to the radio and then to the TinyTrak4. This cable can be bought from Byonics. Then there is a USB cable from the TinyTrak4 to the computer.”

It is also worth noting that you don’t need a radio with a dedicated data port and can often make the connections to the mic and speaker/headphone jacks of a basic mobile radio or HT. Make your own cable using the information in your radio’s user or service manual or purchase one from a company like Byonics: cable selection chart.

For an overview of Packet, VA3ROM has a presentation on VHF Packet which covers scenarios, equipment and examples such as Winlink:
