I would think it would take all of about 10 minutes to turn on the SpaceX stuff and measure its influence on the claimed frequencies from the ground. The Omnispace satellite was 17,000 km away, so any emissions should be easily detected on the ground. The frequencies used are for satellite-to-ground communication, so there's no issue with them being affected by atmosphere.Omnispace's report to the FCC: ECFS
