BOOMERANG DMR hotspot
OTHER INFORMATION
Creating a test channel in the radio
To test your hotspot, you will need to create a channel with the appropriate TX and RX frequencies, color code and time slot. Below is
the configuration for the default configuration that the hotspot is set to
.
TX: 434.0000Mhz
RX: 439.0000Mhz
Channel type: Digital
Transmit power: Low
Band width: 12.5khz
Talkgroup: 9990 (private call) or any talkgroup that you know works
Color code: 1
Time slot: 1 or 2
If your radio uses zones, then a zone will need to be created for this channel.
Other Resources
There are many other settings and features that can be configured on Pi-Star and Brandmeister. The Wikis for these systems are
available online.

Notes
Software:
The Pi-Star software is based on Jonathan Naylor (G4KLX) work and now support the full G4KLX MMDVM suite, including the extra
cross-mode gateways added on by Andy (CA6JAU) who are still supporting this projects. For software support and help, please refer
to https://www.pistar.uk/ and other online pistart forms. This manual is not a Pi-star user manual. These units are shipped
preconfigured. This user manual only covers very basic configurations that are still needed for the user to input.
Antennas:
These hotspots produce a low RF power signal with an expected range of about 100 - 300ft. The stock antenna provided with the
units will best perform on UHF at around 433Mhz. Higher gain antenna can be used to improve the range if needed.
Power usage:
The BMHSPI3 is provided with a 3A power adapter. Using other adapters with less power can cause the unit not to bootup properly.
The BMHSP0 needs about 2A and is provided with a USB cable only which can be used with most USB power adapters
Operating temperature:
The BMHSPI3 CPU typically runs at about 135
o
C while the BMHSPI0 CPU runs about around 120
o
C. This difference in operating
temperature is mainly due to CPU performance and clock. The BMHSPI3 provides a much higher performance and therefore uses
more power and generates more heat. Both units will run warmer if used in an areas that is not properly vented or sunny.
