Rapberry Pies and DVMega / Bluestack HotSpot Toys!

My Raspberry PI / DMR Stack

Been spending a lot of time on DMR (Digital Mobile Radio) these days. Recently ordered a DVMega / Bluestack Node and have been having a ball chatting with people all over the World.

As a matter of fact I had a very nice TAC311 QSO with HL5KY in Korea on 2/4 @ 22:20 hours.

The black PI is a PI3 Mod B where I run my Web Server, custom firmware for the Tytera MD380 called MD380 Tools and do some crazy Java Coding.

The clear PI is a PI2 and I experiment with all kinds of code like the unsupported BlueDV console for the BlueStack Node.

And of course the top of the stack is the HotSpot. Right now the console is an Nexus 7 tablet running Andriod with the BlueDV console. Pleas note my HIGH TECH way of keeping the STACK together!!!

If you are interested in finding out more about DMR, you can listen to DMR Ham Radio Operators talk on the various talk groups. A good place to start is to listen to talk group 3100.

Most of all have fun! 73 KE2YK

 

 

 

A New DV4mini Arrives On Scene

DV4mini USB StickWireless Holdings sells leading edge modules and accessories to Ham Radio operators. Wireless Holdings has been in the digital gadget market over 40 years, and leverages a network of professional engineers to bring the latest digital gadgets to the market.

Why would anyone be interested in a DV4mini USB Stick? First I should explain that the DV4mini is a miniature, low power transceiver which you can use around the house or portable with any HT capable of one of the four digital modes. DSTAR, DMR Plus, Fusion or P25. Download a copy of the DV4mini manual for more detail.

In my case, even though  I live in an area tightly packed with analog RF, there are no digital repeaters close enough to reliably access with an HT. Unless I connect my CS700 to my roof antenna, I cannot reach the DMR TRBO repeater in my area. Visit DMR-MARC if you want to know more about TRBO for Ham Radio.

So using DMR with the DV4mini (although not TRBO) gets me connected to the digital world using DMR Plus (Hytera systems). I cannot speak about DSTAR, Fusion or P25. My only experience has been using DMR Plus. I don’t spend a lot of time with the DV4mini however I had the pleasure of having a QSO with a Ham from Japan a few weeks back.

My 70cm DV4mini has worked flawlessly since I purchased it some months ago. As I mentioned in a prior article, I built up a Raspberry Pi with the necessary software to run the DV4mini console. If anyone is interested in my notes about building up the software necessary to run the DV4mini Console and other Raspian Jessie ramblings,  stop by my homebrew Ham Radio Forum.

Recently I received an email stating that Wireless Holdings will start selling the DV4mini  in a 2 meter version. Just in time for Dayton Hamvention!

A Ham friend, Joe W2OFD has been looking over the articles and videos about the details of the Raspberry Pi Model B Rev 2 board. The Model B board includes 512 Mb Ram, 2 USB ports, SD Card Slot, Ethernet port, HDMI port, Micro USB power adapter port, analog video and an audio port.
