Digirig DRLITE Digital Mode and Radio Control Interfaces
Digirig DRLITE Digital Mode and Radio Control Interfaces are the minimalistic version of the original Digirig DR-891, and deliver the same high-quality audio codec, but without the serial port. The DR-LITE combines an audio codec and PTT switching into a single unit, supporting both GPIO3-based PTT functionality using a specific pin on the CM108 USB audio chip, and experimental VOX PTT by tone via the unused right audio channel. Compatible with Windows, MacOS, and Linux, it uses a single 3.5mm TRRS connector that works with existing Digirig audio cables and a growing range of pre-made cables for popular transceivers. USB isolation can be added easily with a Digirig USB Isolator.
