About the SRPT-03
Turn your Baofeng UV-5R or compatible radio into a fully robust repeater station with the SRPT-03. No need for a duplexer or second radio—this compact beast records your message and plays it back on the same or different frequency. Perfect for emergency situations, it’s built for GMRS and Ham Radio enthusiasts with a rugged edge.
Designed for fast plug-and-play operation, it works with all UV-5R-compatible two-way radios. Equipped with a built-in rechargeable battery (USB-C charging), it’s ideal for off-grid trips where repeater coverage is zilch. Get a weekend’s worth of use on a single charge—small, tough, and ready to roll.
