W3DJS Ham Pi Project Review

I have been experimenting with Raspberry Pi’s for a number of years. As the hardware evolved, I began using the hardware for various Ham Radio projects.

 SVXlink was one of my first Pi 3 Mod B projects. SVXlink is a Linux based repeater controller and echolink server. I did the project for the Brookhaven National Lab Radio club (BNLARC). At the time of this post, the server is offline due to repeater work.

The SharkRF IPConnector is another project I did on a Pi 3 Mod B. A local group, all running OpenSpot hardware used my IPConnector as a private DMR network. The daemon was very stable and the dashboard allowed me to keep an eye on activity. After getting over some of the configuration hurdles, IPConnector was a fun and useful project.

FT8 Off The Grid Setup

My next project was to create an off the grid FT8 system to take portable for Parks on the Air activations. Rather than reinvent the wheel, I leveraged some of KM4ACK’s scripts for time management.

As anyone who has run FT8 knows the protocol requires an accurate system clock.

Installing a hardware real time clock and an inexpensive GPS unit along with KM4ACK’s software tools insured accurate time.    

I have recently moved onto the Raspberry PI 4 Mod B with 8gb ram. Why? The only real reason I can come up with is; why stop now! The operating system for the Raspberry Pi is now officially called the Raspberry Pi Operating System. The Pi 4 Mod B hardware really is another leap forward for an intro $35 computer. Take a spin over to raspberrypi.org for all the cool tech specs. I see no point in regurgitating them here.

Ham Pi, written by Dave Slotter, W3DJS caught my attention because Dave has dedicated an incredible amount of time to this project. Dave has compiled over 100 ham radio apps in various categories and… get ready for it… it’s documented! Not only is it documented but each app in the document has a link to the app’s home page. Way to go Dave!

Dave has broken down his list of applications into 8 categories: General Ham Radio (41) Antenna Tools (5) Digital Software (including the full suite of FLDigi apps) (11) Software Defined Radio (25) APRS (5) Logging (10) Winlink (6) and Morse Code (12).

Got a Raspberry Pi 3 Mod B or new Pi 4? Why not give Dave’s project a spin? Use the comment section for help or questions?

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 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.
