Engineer achieves 80,000 hops/second with AD9361 SDR, confirms Starlink terminals pair uplink-downlink channels via same number; discovers strong RF radiation detectable meters away from consumer dish despite narrow beam design.

80,000 Hops per Second AD9361 Measurement Confirm Starlink Terminal Uplink/Downlink Channel Pairing — and Surprisingly Big RF Radiation

80,000 channel hops per second with hardware-controlled AD9361 frequency hopping I replaced the previous software-controlled AD9361 frequency-hopping implementation, which achieved 10,000 hops per second [1,2], with hardware-controlled hopping, enabling measurements at 80,000 hops per second. The AD9361 measurement system channel is switched every 12.5 µs, allowing all eight Starlink channels to be scanned in just 100 µs. Although the AD9361 datasheet specifies a channel-switching settling time ...
