For those applications which use an audio line only, like Winlink, has been a consideration of an Audio only DR? For one who, just needs WL on a FTM6000, having rig control is overkill. And a way to get more hams into the hobby by KISSing a KISS product.
You’ll still need some PTT mechanism additionally to audio. Digirig uses serial port’s RTS signal for that. It’s possible to use VOX implementation for PTT like Signalink does, but with the delay adjustment is not exactly KISS friendly.
I am a believer in Keep It Simple Succeed. The Digirig has no knobs and three simple connectors.
