I think I'm going to give up on this effort and just use the RT Systems stuff I've already purchased. I have a working serial port tap using a Saleea logic analyzer, and I've been able to capture comms traffic during a "clone TX" from the radio. I've determined that it uses 38400 bps and 0x06 as an "ack" (suggesting commonalities with other Yaesu radios).
Beyond that, I cannot make any sense of the various chirp Yaesu drivers, decipher the data path through the code, or determine anything at all about what the protocol framing of any of those radios is supposed to look like, so I'm not able to compare it with my captured data or identify the memory size it uses. Nor have I been able to find any descriptions of likely Yaesu comms protocols or memory layouts online. Without more information, this task requires better Python skills and far more familiarity with chirp drivers than I possess, so I'm stopping here. I continue to appreciate the effort folks are putting in to support radios on this software.
