I did indeed initially create the file for the UV-9R Pro channel scheme by duplicating a .img file that had been made for a UV-5R, is this what you mean? > 2.

I will do that, thank you! :) _______________________________________________ chirp_users mailing list chirp_users@intrepid.danplanet.com http://intrepid.danplanet.com/mailman/listinfo/chirp_users This message was sent to arch...@mail-archive.com at arch...@mail-archive.com To unsubscribe, send an email to chirp_users-unsubscr...@intrepid.danplanet.com To report this email as off-topic, please email chirp_users-ow...@intrepid.danplanet.com Searchable archive: https://www.mail-archive.com/chirp_users@intrepid.danplanet.com
