Battery and Audio board by Necati TA7MNA

3-4 weeks ago me and my father Özkan (TA7OZX) made the exact board crudely onto a perfboard and it works like a charm then we got the idea to design a PCB to make it easier to assemble. At first I was going to design a suitable BMS and audio circuit and order with PCBA but due to chip shortages in JLCPCB I was forced to use the exact modules I used first.

I assembled the PCB in holiday and it works like a charm. I gave six boards to the other amateurs I know and they loved it and probably they will start to use it soon in outdoor activities.

Protective cover for the QMX+ which also doubles as a stand and storage! by Carl SA0CVK

I've been thinking about a good cover for the QMX+ since i pack very compact, but don't want my QMX+ frontpanel to be destroyed. So i came up with the 3D-model below. I'd love if you like the model and come with suggestions. I am open to modify or add versions as needed!

The panels are all dual-sided and can be put on the front or back of the QMX+.
