Hi. I'm a ham but started with the gmrs
I bought the DB20. For base gmrs.
The programming sucks. I found if you open radio at start up, by holding v/m while turning on. You get different options. So if you chose opened 2m 440 everything is open. Then in the programming you have to change model of the DB20 the same.
This gives you power options and you can do more with the radio. But it is still limited
No copy and paste and if so one line at a time.
I hope the guys on chirp make it available in the menu soon.
