Ft857 and ft891 protocol for the control panel is totally different. We looked in to adapt for 891 but it was not possible

Out of pure curiosity, is this because the FT-891 uses SPI between the control panel and body not normal UART, I reckon the timing requirements would be drastically different.

I don't remember the exact reason, it's years ago. But we borrowed a radio and did some reverse enginering and decided that it was not worth the effort to try to adapt for it.
