Thanks Chris, I am aware of the diff between RS232 and TTL, if you have a chance please look in the support section of my website
WWW.VE2DX.COM?for my Whitepaper called TrueTTL.
I need TTL connection for some of my Yeasu oriented projects, I am hoping the Yaesu Protocol used over TTL on the TUN/LIN connector might be usable for my needs? But can’t find any documentation on it, and no it isn’t CAT, except on the FT8X7, FT100, and FT710 when properly configured, all other radios don’t support CAT on that connector even if it is EVERYWHERE!?!
