RFinder B1 Classic Android DMR, ROIP, and FM HT Radio


Join the world of RFinder Android Radio… and see why our users say…”The Future Has Arrived!

This is the device you've been waiting for! A dual-band DMR/FM handheld that NEVER needs a code plug! Amateur radio communication has taken a tremendous leap in technology through the development of RFinder!

  • DMR over IP (DMRoIP) allows users to connect to over 220,000 DMR amateur radio operators from all over the world without the need for a hotspot or a local DMR repeater!
  • RFinder radios are easy to program with no software needed, and an easy point and click interface!
  • RFinder is the first “Click and Talk Transceiver” utilizing its built-in World Wide Repeater Directory (WWRD). Easily point and click on the repeater you wish to use in the WWRD, and you are connected!

And not only is it the most advanced DMR/FM handheld on the market, it's also a fully-functional Android smartphone! 64GB of storage, 4GB of RAM, and embedded cellular technology and wifi connectivity - which allows you to connect to Brandmeister and TGIF with no external hotspot needed!

RFinder is the most modern dual band FM DMR radio on the market with the bonus of evolving software that incorporates the latest technological innovations!

Subscription to the WorldWideRepeaterDirectory is managed through the app, downloadable through Google Playstore or Apple Store.  This software, once registered, works on any device- including this B1 HT, tablet, phone, and desktop PC!  If you need to renew your RFinder subscription, please visit RFinder Subscription.


AT&T Customers:

"Using this device on the AT&T network may require calling AT&T to register the IMEI. In the event their system loses that registration, you may get degraded performance or no service at all and you may want to request that they install a monitor in their system to ensure your IMEI remains in their system. Contact AT&T at 866-344-6217."
