Notice
As we know,the quality of the crystal oscillator affects the stability of the reference frequency.
The crystal oscillator in our DMR hotspot is imported from the United States and the quality is very good.
Some small seller use the common crystal oscillator produced by some small factories in China.Quality is not guaranteed
Please pay attention to distinguish when buying
As an amateur radio operator, if you don’t have a DMR repeater nearby, or out of the repeater range. Yes, you need a DMR hotspot. A hotspot is simply an internet gateway to a particular DMR network (Brandmeister/TGIF).

When using a hotspot, you need have your own callsign and DMR ID. The hotspots are capable of multiple modes as well, such as D-Star, P25, DMR+, YSF and NXDN.
Why you need a DMR Hotspot?
1.DMR Hotspot will help save your DMR radio battery.
You can only use low power on your radio when connect to a DMR Hotspot.
2. MMDVM Hotspot can allow you monitor many talk groups.
You can set Static Talk groups on your Brandmeister.
3. With a DMR hotspot, you can also track your GPS location on aprs.fi.
The radio which built-in GPS will send GPS MSM messenger to MMDVM DMR hotspot, MMDVM will receive the date packet and then transmit to Brandmeister via the internet, Brandmeister server will forwards GPS information packet to APRS.fi. This enables real-time viewing of positioning and movement trajectories on the aprs.fi website.
