Are you putting the radio in to clone mode before you try uploading to the radio?

Yaesu FT-8900 will download to CHIRP, but will not upload. I get "an error has occurred radio did not ack block at (various numbers, e.g., 520, 584, 9854)"

Please help me find a solution to using Chirp to program the FT-8900 that my wife worked extra hours to give me for HER birthday. HRO wants another $40 for programming software.

Please help.
