An open-source 240-antenna array to bounce signals off the Moon

Wild hardware flex for a garage project. Reverse-engineering the Pi 5's MIPI to push 5.6 Gbps from custom MASH sigma-delta ADCs to a Lattice ECP5 FPGA to the Raspberry Pi is serious engineering. The idea that the RF receiver looks like a "camera" to the Pi while the transmitter is a "display" is super creative. Getting a 1.5 kW, 240-antenna EME array for $2,499 is actually cheap for something like this. Their standalone 4-antenna tiles ( https://moonrf.com/updates/ ) show off some killer apps, like 30 fps spatial RF visualization and NEON-optimized drone video interception. I'm rolling my eyes at the "Agentic Transceiver" part, though. It is highly doubtful that an onboard AI casually writes, debugs, and compiles a real-time C app with analog video color sync recovery and decode in ten minutes.

Cool, how full array compares to the single antenna placed on Starlink satellite ?
