Current CHIRP files. Suggest that you download from your radio FIRST, then EDIT by copy and paste of all these frequencies, and THEN upload back to your radio to avoid “issues.”

(This is a safe file to download.) You will need CHIRP (free software: https://chirpmyradio.com/projects/chirp/wiki/Download that a bunch of us use….) and a programming dongle for the Baofeng (see AMAZON) I recommend one that has the FTDI chip — they cause less problems even though they are few $ more expensive.
