Found a bug. Tried both RC39a and the newer RC39b where the former TBS SA protocal does not work. I do not have any SA2.1 capable VTX units to compare to to verify if there is an issue on the newer SA protocal.
Current VTX is the TBS Unify Pro HV Race 7 pin and non race versions (audio and smart audio are two separate lines) using the former protocal.
