Audio Sample


IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. data provided. Samples sound like popping static. A waterfall plot is more indicative of the spread spectrum nature of this signal.


Frequency hopping spread spectrum signal. ASKAmplitude-Shift Keying encoding per packet.

From 902-927MHz. .175MHz with equal spacing through chunk of spectrum. Cannot accurately tell exactly the channel boundaries.

Decoding Software[edit]

None available

Used Universal Radio Hacker to capture samples. One needs 30MHz bandwidth to capture and follow a signal.
