Surveys

Twelve hours of RTL-SDR sweeps over 144–146 and 430–440 MHz from my home at KP10CL: repeaters, unknown carriers, ISM devices and the SDR's own spurs.

Two hours of RTL-SDR sweeps over 863–873 MHz from my home at KP10CL: MeshCore on 869.618 MHz, a likely LoRaWAN downlink at 869.525 MHz, uplink activity at 867–868.6 MHz, and SDR overload from strong bursts.
