I have only uploaded CS750 and Hytera PD365 codeplugs, there are no TYT / Tytera codeplugs here on this site. I have heard that CS700 codeplugs can be converted to MD380 and visa versa.
MI3UTY it looks like you would be operating through GB3OM and/or GB7LY, I am sure someone with a MD380 could write you a 2 Zone codeplug to get you started..
