What is the **OHIS Radio KISS Adapter**?

It is an adapter intended to bring any radio no matter its wiring standard or level from a Professional, Ham, DIY, Cheap Chinese, or Crystal with a Wire Hanging out of It; to be compatible with the OHIS connection Std. with very little to no effort other than looking up your radios needed connections and connecting said wires to the OHIS Radio KISS.
