Disregard, I finally got it working. The RT Systems directions are confusing and inaccurate, much the same as the FT-60 software. If you're using a Mac, be prepared to improvise heavily. It did work eventually by using the FAT format on the SD card via the Mac disk utility. "Same issues with FT3-DR. I followed some of the tips above and formatted the SD card as FAT (MS-DOS) using the Mac OS disk utility. It's a class 3 micro SD. I was able to get the FT3 to download it's .dat file and then used the FT3 programmer to load the presets. On reloading the SD to the radio, it can see the SD but won't load the presets. 'Read from SD' option does nothing. Appreciate any (Mac OS) ideas."
