What is Ham radio hotspot?
A personal, low-power hotspot is a combination of hardware, firmware, and software that enables an amateur radio enthusiast with internet connectivity to link directly to digital voice (DV) systems around the world. Hotspots can link to DMR, P25, and NXDN talkgroups; D-STAR reflectors; YSF rooms; and so on.
What is a PI star?
Pi-star is a system of pre-packaged software and firmware that permits a Hotspot to be implemented on a Raspberry Pi (software) and ARM-based controller of an Analog Devices 7021 RF modem (firmware). Pi-star permits many of the Hotspot functions to be performed via a web interface.Feb 17, 2019
What is the range of a DMR radio?
30 MHz to 1 GHzDMR covers the RF range 30 MHz to 1 GHz. There are DMR implementations, (as of early 2016), that operate as low as 66 MHz (within the European Union, in 'Lo-Band VHF' 66–88 MHz.) The DMR Association and manufacturers often claim that DMR has superior coverage performance to analogue FM.

Can you use DMR without a hotspot?
You would use a hotspot when you either don't have a DMR repeater nearby, or simply don't want to tie it up for any length of time. Many hotspots are capable of multiple modes as well, such as D-Star, P25, DMR+, YSF and NXDN… but we are only going to talk about DMR here.
How does DMR radio work?
DMR is a TDMA mode (Time Division Multiple Access) which means that it allows several users to share the same frequency channel by dividing that signal into different time slots. Each frequency has a slot 1 or slot 2 and each slot can be used by different users.
