This Hotspot is running the WPSD system. Many say it is an easyer format and setup. The dashboard is better looking then Pi-star and has a lot of features you don't see in pi-star.
This is small so you can put a little power bank on it place it in your pocket and have it with you all the time like I do. I just use my phone's hotspot for internet, and it runs about 3 to 4 hours.
This is Duplex so no more waiting for the long-winded talker, go to time slot 1 or 2 and put it on a new talk group. Now you can switch back and forth between talk groups easyer, it is like having 2 hot spots.
