I have two handheld radios - Yaesu FT-70D and FT-3D. Unfortunately Yaesu have two different programs to communicate and update the memory ADMS-10 for FT-70D and ADMS-11 for FT-3D.
I had all my channels in FT-70D and it turned out that the csv export from ADMS-10 is not recognized by ADMS-11. So you can't easily transfer memory channels from FT-70D to FT-3D. ADMS-11 can import from some other radios but not from FT-70D.
This is a short script which converts csv export files from ADMS-10 to ADMS-11 format. I will add later also the opposite script - convert from ADMS-11 to ADMS-12, so I can copy all channels from FT-3D to FT-70D.
python3 convert_ft70d.py <export filename>.csv
