Thanks to Tom Hayward <tom@tomh.us mailto:tom@tomh.us> for unblinding me to the hg “add” function. I’ve now submitted a new support suggestion. I think it’d be A Good Idea to add the required instructions to the “Add_A_Radio” section of the blog, since one doesn’t add a whole file very often.

What he said worked a charm, AND correctly diagnosed my problem with the instructions;

I think the issue is the the instructions are written for making changes to files, and you're trying to add a files. To add the new file to the patch, try this:

hg add chirp/drivers/ft2.dpy hg qref hg export tip
