’m trying to import a csv file into CHIRP to upload back to my radio.

Steps I’ve taken:

1. Connected radio to CHIRP and downloaded the memories to CHIRP
2. Exported memories to a CSV file
3. Added the new frequencies to the CSV file
4. Saved CSV and tried to import back to CHIRP bur getting an unknown file format message

What am I missing?

Thanks for any help!
