SuperSpot

I have decided to build a SuperSpot from scratch by downloading the source and compiling the code and putting it in a box with a MMDVM board for each mode I plan to use. The build process started about 3 week prior to the holiday my XYL and I took in Lanzarote, Canary Islands, Spain in September 2019. Thinking that I needed a hotspot that I could use a variety of radio’s at the same time and not have to wait for the last mode used to time out before I could used a different mode.

Discussions with Andy MW0MWZ consisted of what to use, how to connect, how to power/charge, how to get internet into the box and finally which modes to include. What we finally settled on was a hotspot that has 1 Raspberry Pi, hopefully a Raspberry Pi Zero W would handle the work load with a second choice being a Raspberry Pi 2. The plan being to connect 3 or 4 MMDVM board and the same number of  2.4″ Nextion Screens to monitor what is happening on the hotspot. There isn’t a need for a dashboard as the user doesn’t see a dashboard when using a repeater, so no need to add a dashboard on the SuperSpot.

Work commenced on the SuperSpot build by setting up the software side on the only MMDVM board I had with me. This was a HS_DUAL_HAT and was setup for DMR with a temporary addition of POCSAG which will either move to its own MMDVM board or piggyback off the D-Star board.

Additional MMDVM boards were ordered to be delivered to my home QTH along with a couple of USB to TLL converters via Amazon for connecting to the Nextion Screens. The Nextion Screens be the next items to order.

So let get on with the build. We will start with Part1 – MMDVMHost Software
