Short Description

'Out of Band (Australia)'

Unidentified digital wideband signal seems to have origins in the US ISM band - Shouldn't be below 915MHz Downunder!

Out of Band (Australia)

Unidentified digital wideband signal seems to have origins in the US ISM band - Shouldn't be below 915MHz Downunder! The signal extends 'out of band' (below 915MHz in AU) and under full load exhibits big wideband pulses as shown. Normally under lighter load there are 200-250kHz TDMATime Division Multiple Access/FDMAFrequency Division Multiple Access blocks scattered in time and freq across 12-18 MHzMegaHertz (MHz) 10^6 Hz. I suspect this is some kind of US ISM product not approved for use in AU. Not 100% sure of mode and/or modulation (very fast).
