CQRADIOS.COM

Description:

The Boomerang DMR hotspot repeater is based on the Pi-Star software, uses 
a duplex MMDVM board and comes with dual antennas. This unit allows for 
usage of both time slot 1 and time slot 2 simultaneously. It uses a large OLED 
with a white-on-black configuration display for better viewing. It also 
provides both WiFi and RJ45 network connections and comes in a 3D printed 
case.  

The Boomerang hotspot comes preconfigured to require minimal setup by the user.

1 - Using the LAN (BMHSPI3 only):

• 

Type pi-star.local on a web browser in a computer that 
is connected to the same LAN

• 

If the pi-star.local does not work, use the unit

s IP 

address instead of pi-star.local

• 

The IP address can be found through the router or 
using an IP address network scanner software. 

2 - Using wireless (BMHSPI3 and BMHSPI0):

• 

Using a laptop or smartphone, look for
