Aubrey, I think you are referring to the KX3 Companion for Android by Andrea IU4APC.
I have tried this for lightweight operations. It woks by sending out commands to KX3 in ASCII over serial. Android<>OTG Adaptor<>Serial to USB<>KX3. If you want the waterfall to work - which us optional - I use the KX3 headphone output into the 3.5mm audio jack on my Tablet. This worked OK on my old Nexus 9. Some tablets don’t recognise the microphone input . The Android Headset Tester is a good bit of Freeware which you can use to check the microphone is recognised. Some tablets need an extra low resistance ( 1k3 ) to recognise a microphone is plugged in. PSK31 and Morse are sent as ASCII and the KX3 does the translating to the signals to modulate the SSB. I&Q aren’t needed. I don’t use PSK31 any more but have moved to JS8Call and FT8 and hope we might get an internal KX3 or Android implementation.
