Welcome to my website. Here you will find information on the various project I have for robotics, astronomy, sailing, Holiday display and other misalliances items. You can contact me at:
This project attempts to integrate every ham utility using the raspberry pi. Programs include fldigi, echolink node, packet, SDR, and many more. The goal is to provide an easy way for people to just copy the sd image and not worry about all the setup involved in getting these software running. This project is always evolving, so more utilities will be added. The are many varieties for what type of hardware you choose, but the most imported thing is the Raspberry Pi and a sound card (the pi does not have a mic input). Here are the hardware that I have setup for this. Required hardware: All of these will set you back about $65. There are PI packages out there that will sell you the pi, the power supply case and sd card, so you might be able to go even cheaper. You will also need a keyboard, mouse display, and a wifi dongle. These are optional, since you could run an echolink node without them (or temporally hooking them up for setup). Get the wheezy raspbian image from here: http://www.raspberrypi.org/downloads Once the file is downloaded, extract it and write the image to an sd card. You can use dd if you are on linux or Win32DiskImages on windows. If you are new to this, you can follow the easy step by step instruction here. Once the pi has booted, you may want to use the initial setup screen to increase the fs system, change the keyboard layout (if you are in the US), and change the password. To setup fldigi, you would need to download a patched version from this web site if you want to use the GPIO pin as a trigger for the PTT. Once the file is downloaded, configure and compile it. Additionally, you will need a script to setup the gpio. This script can be part of the bashrc file so it will start automatically. You can follow the step by step instruction bellow, which will also download the file. Here is a link to the patched version: fldigi-3.21.76_patched.tar.gz Here is the patch if you know what you are doing: fldigi-3.21.76_gpio.patch Script to setup the gpio (must be run as root): setGPIO Once this script is done (it will take a very long time, just Ham it up in the mean time) reboot the PI, log in and type startx. You should see fldigi under the internet tab Once you fill in the basic configurations for the callsign, QTH, etc you would need to configure the audio devices as follow: select OSS and set the device to /dev/dsp1 For NBEMS, you can download the fldigi src suite from the website configure, and compile it. todo I have tested almost all the modes with fldigi (did a test with K6POI from pi to pi), and it seems like the pi can handle all the modes very well.
