@InnovateDefence Yeah, I also tried to "sell" my MarlinRF SDR HW/SW solution to the Cyberagentur for maritime BLOS LPI/LPD rf-comm but they weren't interested 🤷. I'm always wondering where the good stuff is happening 😅
@DroneShield Agreed. Periodic scanning leaves windows. Dense, low-cost spectral nodes that stay online are what actually closes the electromagnetic perimeter.
