Dual-band 2m / 70cm (ham)

Radioddity GM-30 / GB-75 class

Step up from bare Baofeng: better fit/finish, USB programming, often clearer audio. Good “first serious HT” after passing Technician.

Technician or higher · Mid ($50–$90)

Quick start

First-hour checklist

  1. Install manufacturer USB driver before connecting to CHIRP.
  2. Import a regional repeater list, then delete unused entries to reduce scan clutter.
  3. Label side buttons for priority simplex and home repeater.
  4. Test with a rubber duck on 2m simplex before relying on 70cm in hilly terrain.
Programming

Software & memory workflow

  • CHIRP support varies by exact model — confirm on CHIRP wiki before purchase.
  • Set per-channel power levels — low indoors, high only for marginal repeaters.
