The terms MMDVM hotspot and Jumbo Spot are used interchangeably. MMDVM stands for Multi Mode Digital Voice Modem.
Hereof, what is Mmdvm?
The MMDVM is intended to be an open-source Multi-Mode Digital Voice Modem, which utilities the power of an ARM processor and a simple analogue interface board. However such boards are very useful for hosting the interface of the modem to external networks such as ircDDB in the case of D-Star.
what is a ham radio hot spot? 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.
Likewise, what is a Mmdvm hotspot?
A hotspot, simply put, is your internet gateway to a particular DMR network. To start, here is a great video that walks you through how to setup Pi Star on a MMDVM Hat hotspot. This is a very common hotspot configuration and one that really sets the base for understanding how they work.
What is a Zumspot?
The Zumspot board, when paired with the Raspberry Pi Zero W is a very small portable hotspot that you can take anywhere. The Pi Zero W features built in wi-fi and Bluetooth.

What is a jumbo spot?
The Jumbo Spot allows Hams to operate on one or more digital modes without the use of a repeater. The Jumbo Spot basically becomes your private repeater.
Do I need a DMR hotspot?
Yes, you need a DMR hotspot. A hotspot is simply an internet gateway to a particular DMR network (Brandmeister/TGIF). DMR Hotspots have become very popular due to the expansion of the Brandmeister Network in recent years.
What frequency should I use for DMR hotspot?
With the advent of hotspots for digital modes such as the sharkrf OpenSpot and DVMega, finding an open frequency has become an issue. Many of the frequencies I’ve seen on the brandmeister network for hotspots are between 432-433MHz (the weak signal portion of the band) or between 435.0 and 438.0 MHz.
What is DMR mode?
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.
What is a Dstar hotspot?
The range is very limited, but the ham can use his or her radio (and computer) to connect to a repeater or reflector without a D-STAR repeater in range. A D-STAR Hotspot is like a homemade DVAP made using an FM radio with a data port, a GMSK adapter board, and a computer.
What is the BrandMeister network?
BrandMaster/BrandMeister is an operating software for Master servers participating in a worldwide infrastructure network of amateur radio digital voice systems. If you are an amateur radio operator working in digital voice modes like D-Star, DMR, C4FM, APCO P25 or others (not all are supported yet!!).
What is a digital repeater?
1) In digital communication systems, a repeater is a device that receives a digital signal on an electromagnetic or optical transmission medium and regenerates the signal along the next leg of the medium.
How does DMR radio work?
DMR digital mobile radio uses a 2 channel TDMA, time division multiple access scheme. The transmission is split into various blocks: Burst: Each transmission burst is nominally 30 ms long and this consists of one TDMA element. Each burst can either be for one TDMA channel or the other.
