Digirig DR-891 Interface Kit for Yaesu FT-891

USB digital modes interface kit for Yaesu FT-891 including transceiver cables.

The cables in this kit are not sold separately because they can not be used with other Digirig Models. DR-891 is the only Digirig model that supports a downlink USB connection (red socket). This model of Digirig can be used to interface other transceivers with the functionality equivalent to Digirig Lite. Connect any of the standard Digirig audio/PTT cables into the black socket labeled “audio”.

Do not plug anything into DR-891’s colored socket labeled “USB” other than the cable with the red molding included in this kit or cable from the accessory kit.
