You'll need to "unzip" the image first to decompress it. On Linux, it's unzip digipi-1.9-1.zip Then flash it to your SD card. It'll fit on a 4G card with room to spare. Look up how to do this. On Linux, it's dd if=digipi-1.9-1.img of=/dev/sdX bs=4M where sdX is the drive letter of your blank SD card (run dmesg to see). On Windows, try this. On Mac, try this. Boot the Raspberry Pi with the newly flashed SD card. Wait for the "DigiPi" wifi hot spot to appear on your phone or pc's wifi settings. Connect to the "DigiPi" hot spot with password "abcdefghij" In a web browser, visit "http://10.0.0.5/wifi.php" Enter your home wifi ssid and password and reboot. Once booted on your home network, visit the website http://digipi/. If the host isn't found, login to your router and look for any newly connected wifi devices, and use the associated IP address. Also check to make sure the DigiPi hotspot no longer exists, if it still exists, this is a sign it had trouble connecting to your home wifi. Also try "http://digipi.local/" Now that the DigiPi is on your home network, click the "Initialize" link at the bottom of http://digipi/. You need to add your callsign, passwords, grid squares and other localization items to your Pi. Keep in mind, once you change a value, you can't use this process to change it again. See /home/pi/localize.env for things you can change after-the-fact. click [Initialize] Once changes are made, reboot the DigiPi by clicking [Reboot] at the bottom of http://digipi/. This will boot the system back into firmware (read-only) mode. Enjoy your DigiPi!

Additional information

The "pi" user password is "raspberry" If not using a USB radio this expects a single audio device, possibly the FE-Pi Audio Z v2, or Audio Injector Z. Edit /boot/config.txt to switch between these two audio hats. The default is currently the FE-Pi. The filesystem is "read only" to prevent SD card wear and so you don't have to do a clean shutdown (just turn off the power is fine). To make modifications, you must "sudo remount" first. WSJTX/sstv/js8call will need to be configured within each app. Yaesu 991 is rig 1035, device ttyUSB0, baud 38400 Icom 7300 is rig 3073, device ttyUSB0, baud 19200 Icom 705 is rig 3085, device ttyACM0, baud 115200 Once you've configured wsjtx/sstv/js8call/fldigi, be sure to press [Save Configs] on the http://digipi/ home page to commit these changes to the SD card so they'll be present on next boot. See the supported rig list for more information. The GUI apps (js8call, fldigi, ft8, sstv) can be used with a VNC client on your phone. This can be considerably easier to use than a web browser, particularly when it comes to typing, zooming, etc. "VNC Viewer" on Google Play is sufficient. The VNC login parameters are: host: "digipi:5901" or "10.0.0.5:5901" in the field password: "test11" Direwolf will exert a voltage on gpio pin 12 for Push-to-talk. For home brew hardware, use this signal to short your PTT wire to ground with a fet (N7000). If you hookukp a green led (with 220ohm resistor inline) to gpio pin 16 it will light up when direwolf detects a carrier. If you hookup a red led (with 220ohm resistor inline) to gpio pin 26 it will light up on transmit. If you hookup a blue led (with 220ohm resistor inline) to gpio pin 5 it will light up if you connect a bluetooth device like aprsdroid. I used a 3.2K resistor with this blue led in my implementation because blue leds are oddly bright. If you'd like to change the hostname (and bluetooth name), edit /etc/hostname and also add your hostname to the list next to 127.0.1.1 in /etc/hosts. To use a bluetooth app (aprsdroid, woad) you'll need to pair the device first sudo remount sudo systemctl restart bluetooth sudo bluetoothctl scan on # on phone/wifi device, open bluetooth settings, make visible for pairing # watch for [NEW] Device FC:19:10:F7:55:C8 Device_name pair FC:19:10:F7:55:C8 # click [pair] on phone yes # on bluetoothctl prompt # press [yes] on droid device trust FC:19:10:F7:55:C8 quit # the USB led/icon will illuminate momentarily on the DigiPi shutdown -r 0 When configuring aprsdroid, in connection settings, connection type, select "Bluetooth SPP". Select Channel "1". TNC Bluetooth Device should be "digipi". Buttons on the display will start the igate or digipeater services. Adjust the volume on the receiver while "tail -f /run/direwolf.log" until the average audio volume is around "50(x,y)." Run alsamixer and adjust the "line" level, while listening to transmitted packets to make sure they're not overdriven, and about the same volume as other aprs radios in your area. the APRS Digipeater service will repeat WIDE1-1 traffic and relay all message-type packets sourced from the internet to targets within 160km of your digipi. Adjust ~/direwolf.digipeater.conf to taste. The device becomes a hotspot if you don't setup your wifi, in which case the ssid is "DigiPi" and the default password is "abcdefghij". You'll find the device at http://10.0.0.5/ . If you're in the field, obviously, this will be its address.
