Programming Files for Radios (Codeplugs)

The standard W0TLM frequency list includes many of the common 2m / 70cm simplex and repeater frequencies for our area.

Please bear in mind that some portions of these files may change.  You may want to rename and personalize necessary labels for your own radio.

Chirp radio programming software is available at: https://chirp.danplanet.com

New Rev 13 (18 May 2023)

Changed K0NR repeater to W0TLM repeater, added two memories for the W0TLM portable repeater, simplified the pdf file for easier reading, and reduced the number of simplex channels.

Note that the manufacturers often change their radio firmware (especially Baofeng) so the file above may not match the revision of firmware in your radio. If so, a good approach is to use Chirp to download the existing radio programming, open the new programming file and do a copy-and-paste of the information into the existing radio file. This usually solves the firmware incompatibility issues.
