![]() ![]() Once you fill in the basic configurations for the callsign, QTH, etc you would need to configure the audio devices as follow: You should see fldigi under the internet tab Configuring FLDIGI 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. Script to setup the gpio (must be run as root): setGPIO There is an automated script that I created that can be used to set all this up, once you log in to your pi exec the following command Here is the patch if you know what you are doing: fldigi-3.21.76_gpio.patch Here is a link to the patched version: fldigi-3.21.76_ You can follow the step by step instruction bellow, which will also download the file. This script can be part of the bashrc file so it will start automatically. Additionally, you will need a script to setup the gpio. Once the file is downloaded, configure and compile it. 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 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. If you are new to this, you can follow the easy step by step instruction here. You can use dd if you are on linux or Win32DiskImages on windows. Once the file is downloaded, extract it and write the image to an sd card. Get the wheezy raspbian image from here: The DTR pin connects to GPIO 17 (pin 11), and the DIG GND connect to the GND connection on the pi. Heat Sinks for over-clocking the pi: $5.99 from amazon.Ĭonnect the Raspberry PI to the EasyDigi using the diagram bellow.Cheep VGA display (about $50), Other options include an hdmi display for $54 from ebay, or PiTFT for $34.95 (I have not used that yet).These are optional, since you could run an echolink node without them (or temporally hooking them up for setup). You will also need a keyboard, mouse display, and a wifi dongle. 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. More storage is better but not necessary.Īll of these will set you back about $65. You can also go the SignaLink route which is the simplest but will set you back $100. The PTT connects directly to the GPIO on the pi, so I believe this is the best method, as it lets the pi have full control over the radio. You will still need to solder the connectors, so might as well solder the components (took me 5Min). There is also an assembled version in case you dont want to solder EasyDigi Assembled. Sound Card interface: $8.95: There are many methods of connecting your rig to the sound card, but the cheapest and safest way I found is to use the EasyDigi.Raspberry Pi Model B (512MB): Can be found from many places for about $35-$40.Here are the hardware that I have setup for this. 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). This project is always evolving, so more utilities will be added. ![]() 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. Programs include fldigi, echolink node, packet, SDR, and many more. This project attempts to integrate every ham utility using the raspberry pi. ![]()
