The Shark OpenSpot3 is a digital mobile radio (DMR) hotspot device that allows users to connect to DMR networks, such as DMR-MARC, BrandMeister, and DMRPlus, using a standard analog two-way radio. It is a small, portable device that can be connected to a computer or mobile device to access the hotspot, and it allows users to communicate with other DMR radios on the network. The device supports both Tier I and Tier II DMR, as well as DMR trunking, and it has a built-in OLED display for easy configuration and monitoring. It also supports other digital modes like D-STAR, and YSF.
The Shark OpenSpot3 is capable of cross mode operation, which means that it can allow communication between radios that use different digital modes, such as DMR, D-STAR, and Yaesu System Fusion (YSF). For example, a user with a DMR radio can communicate with a user with a YSF radio, and vice versa.
When using cross mode operation, the OpenSpot3 acts as a bridge between the different modes, translating the digital audio and data between them in real-time. This allows users to communicate with others on different digital networks or with different equipment, expanding the range of people they can reach.
For this feature to work, the radios need to be configured to talk to the OpenSpot3 and the OpenSpot3 needs to be configured to bridge the different modes, this can be done via the web interface. It’s also important to note that not all the features of the different modes may be available when using cross-mode operation.
