ARRL Repeater Directory
Corrections and Additions
Since 2017, the listings included in The Repeater Directory have been supplied by RFinder. RFinder offers an online subscription
service to its worldwide repeater database (sold separately). ARRL does not curate the listings included in the Repeater Directory.
We encourage frequency coordinators and repeater owners to review listings published in the annual Repeater Directory,
and to submit corrections directly to RFinder.
RFinder subscribers can search for, and request updates, to repeater listings there.
You can submit a request to add a repeater to the RFinder database
Repeaterbook.com is updated daily and is free. It allows various database searches and any web browser can connect.
