Digital radio or digimodes?

Digimodes is easy enough, you just need an interface that connects to the mic input and a feed from the speaker-out.

I made one years ago, but I used manual switching and fed raw audio into the mic input from the PC sound card. I knocked up a switch to TX the radio and then fed the audio-out from the radio direct into the line-in of the PC Sound card..... a bit rough and ready, probably prone to feeding too much into the radio and popping something, but worked short-term. Certainly good enough to get started and mess about. Just to RX you wouldn't even need a TNC, just feed the audio from your speaker out direct into your line in, or even your mic input, albeit on a very low volume setting. K7AGE even demonstrates on his webpage that decoding is possible by just putting your PC Microphone next to the speaker of the radio. You could (in theory) TX the same way, by keying the mic next to your PC speaker, but wouldn't be ideal. Check him out on Youtube

I use a Sigalink USB now. The beauty of this is that it has a cat5 interface on the back, so using a cat5 patch cable, you can make your own break-out cables, following the pin out guide from Signalink and a mic-wiring diagram for the radio you're using. I had cables made for an old Midband AM/FM set I had and even my Fidelity 2001. I had hoped to run a node on one of the bands, but I got side-tracked and never bothered.
