Jonathan GI3JMC's WAOARC Kit Build After the 2025 Worked All OARC kit was presented on Sunday 20th July, and the order link was published, I immediately ordered it then started wondering what to use it on. I settled on the following bits which landed on my doorstep on Tuesday 22nd July (well done PiHut!): * Raspberry Pi Zero 2W * Waveshare UPS Hat * Raspberry Pi Power Supply * Colour-coded GPIO header I managed to get the GPIO header soldered into place the right way round and bolted the UPS hat into place. {{ :waoarc25:gi3jmc:pizero_ups_hat.jpg?400 | }} I rummaged in the 'little parts' box and found an 8Gb MicroSD card, and used the Raspberry Pi Imager to put the current 32-bit 'Lite' version of Raspberry Pi OS onto the card, checking that the customization settings were setting the Pi's network name, adding my WiFi details, a username, and a password. Once the card was written I put it into the Pi Zero 2W and started it up. The first startup takes a little while as the system resizes itself to use all available space on the MicroSD card, so I went and got myself some coffee. {{ :waoarc25:gi3jmc:pi_imager_os_selection.png?400 |}} Once the coffee was finished, I opened a command line and connected to the Pi using ''ssh''. My username is ''jonathan'' and the pi is ''wspr-pizero2''.\\ ''ssh jonathan@wspr-pizero2'' Now that the Pi is running and I've connected to it, I updated it with ''sudo apt update && sudo apt upgrade -y'' and restarted it with ''sudo systemctl reboot''. I reconnected via ssh again, and started to install the software to run the OARC-designed WSPR WithOut Tears hat, called ''wsprrypi'', folling the instructions at [[https://wsprry-pi.readthedocs.io/en/latest/Install/index.html#install-wspr|https://wsprry-pi.readthedocs.io/en/latest/Install/index.html#install-wspr]] The command ''curl -fsSL installwspr.aa0nt.net | sudo bash'' started to download and run the install process, which took between 15 & 20 minutes on the Pi Zero 2, with 9m30s spent compiling the actual software. Once it finished I restarted the Pi for good measure. After the restart a webpage was available at ''http://wspr-pizero2/wsprrypi'' to configure and enable the transmissions. I entered my callsign and saved the page, not yet flipping the transmit enable switch. That needs to wait until I receive and build the kit & filter. {{ :waoarc25:gi3jmc:wsprrypi_config_webpage.png?400 |}}
