Bucket Cross-Band Repeater

A cross-band repeater in a bucket project:
"The “Bucket Repeater” is a battery powered cross-band VHF/UHF repeater in a weather proof enclosure that can operate unattended for a week or more, and be remotely activated or deactivated from miles away as needed."



He uses a Puxing PX-UV973 for the radio and has a complete parts list.
