DV Hotspots – Rethink — Again

Yet another re-think about my hotspots. First I am building a portable SuperSpot which I am also creating build details that will be available for all once the build is complete. Once the build is complete I will then proceed with my other hotspots and how they will play their role in my Amateur Radio Experience.

The SuperSpot will consist of one Raspberry Pi driving 3 or 4 MMDVM boards with one of those being a Duplex MMDVM board running DMR.

More details later when they become available.

Personal DV MMDVM Hotspots

I currently have 3 hotspots in use and plan to active a 4th one in the near furture.

Notes

  1. Hotspot Nº2 is a portable/mobile hotspot and is used mainly at work and other location away form home. I power it either via a DC to DC converter or a battery power pack I purchased from Amazon.
  2. A Dual TS board is planned for this hotspot leaving the DMO board available for inclusion in a planned portable hotspot.
  3. I have another DMO hotspot on order and will update what it will be use as when it arrives.

 

MMDVM HS_HAT Dual

Recently acquired a MMDVM HS_HAT Dual and have set it up as my portable hotspot and I can now enjoying both Time Slots on DMR. The only downside is I now carry two DMR radios.

UPDATE: 17 March 2019

I have ordered a second board that will be used at home QTH.

New Website – Update

Website complete. Now to work on the radio section of the system.

My ADS-B receiver is working. The antenna is made and the feed coax of acquired. All I need to do now is run the coax and mount the antenna. Put the receiver in its final working position and then that job is complete.

The receiver is running on a RPi 3B+. The OS for it is Raspbian and the website where you can download you copy is HERE

I will get to the antenna etc after I take a well-earned break on a Greek Island with the XYL that she has organised. This will be the second holiday I have taken in approximately 5 years.
