SRPT-03
User's Manual
Overview:
The SRPT-03 is an affordable repeater system
designed for GMRS and Ham Radio enthusiasts. It
offers fast plug-and-play repeater operation and
works with the Baofeng UV-5R and compatible
two-way radios listed below. This repeater comes
equipped with a built-in rechargeable battery that
can be charged via a USB C connection, making it
an excellent choice for trips where repeater
coverage is unavailable. The internal battery can
provide a weekend's worth of use on a single
charge. It's simple to use and works right out of
the box.
Configuration can be performed using a web
application. The repeater can be powered either
by the internal battery or the USB port located
on the top of the unit. Real-time LED indicators
provide operational status updates. DTMF tone
detection allows you to enable or disable the
repeater directly from the field. Additionally, an
open frame design allows for compactness, and
plastic shields can be attached for added
ruggedness when needed. The SRPT-02 also
supports CTCSS on your radio for added privacy
and interference prevention. Currently, it
supports UV-5R and compatible radios.
