Review: Straight forward configuration, worked flawlessly. I have used this hotspot with several DMR software packages and it has performed exactly as expected. RF performance and sound quality exceeded my expectations, to be honest. The value is incredible, just mount this in any cheap pre-fab housing or print your own. Connectivity and configuration are simple for someone that is interested or experienced in digital modes, it's an easy DIY and a fun way to learn something that resembles the repeater side of radio for novices.
Review: Works well when the firmware is updated however if you follow the instructions provided for the jumper position, it will not work. The jumper needs to be from bottom center to bottom right, not bottom left as shown in the instructions. Boot 0 center to Boot 0 - (not +).
