A computer with a sound card interfaces to your radio via two 3.5 mm audio cables. An interface cable will be required for this, which you can either make yourself or order one from Clifford Wareham (https://www.ebay.com/usr/cliffordwareham?_trksid=p2047675.l2559). Once you have your interface, you will need to determine what hardware (computer) and what software (the APRS digipeating software) you will use. For my setup, I went with a Raspberry Pi 3– a well documented and reliable miniature computer that runs Linux. The Raspberry Pi 3 does need a USB sound card in order to work as a digipeater, since the Pi only natively supports audio out. The Pi 3 and a USB sound card should cost no more than $50.
