A 219 MHz proposed FCC rule-making (US-centric) workshop is in planning for late October 2024.

If you would like to help with this effort, please join ORI at https://openresearch.institute/getting-started and indicate your interest in addressing spectrum management issues with the 219 MHz band.

In short, it's a completely unused amateur radio allocation due to outdated rules. We can and should try to fix this by proposing sensible and workable rules, so that amateurs can operate on this band.
