The OHIS interface aims to replace the custom connections cables between your radio and headset, TNC, handmic, by a single interface.
If you have many different radios and headsets, TNCs or handheld microphones, you'll be able to connect them interchangeably without having to buy custom cables for each and every one of them.
First phase is to create OHIS interface for Yaesu FT-65E and Midland G9 Pro.
Second phase will be for creating TNC with OHIS interface.
Third phase will be to create Digirig Mobile with OHIS interface.
