Location
Short Description CDMA2000, known primarily as 3G mobile, is a family of 3G data protocols used to send voice, text and signaling data to smart phones and other wireless devices.
I/Q Raw Recording
Audio Sample

This is from the 1900 MHzMegaHertz (MHz) 10^6 Hz band. I captured it with 6 MHzMegaHertz (MHz) 10^6 Hz bandwidth and stretched the front-page image to 3:5 like they want but a to-scale copy may be seen below. Here's the IQ File.

Samples[edit]

Here's one file I captured in 873 MHzMegaHertz (MHz) 10^6 Hz band. This was in HDSDR, so the slots are better heard instead of the ear raping noise in AMAmplitude Modulation. Ywsia1


This second one being captured in SDR# (narrower bandwith of course), this time with the ear raping noise. Ywsia1
