I've made another of these. It's to be used on my 10gHz eme. I'm replicating a lot I've built before for 23 that are proven to work.

2026-04-08 17:05 UTC. Reception of raw telemetry at the same time from two newly deployed, as yet unidentified satellites, on ~401.500 MHz. It could be the pair of 🇺🇸 Army-funded CubeSats called Rawhide, launched aboard the Minotaur IV vehicle from Vandenberg SFB on April 7.🤔
