Location South Carolina
Short Description Possibly a 3G WCDMA signal, although a bit wider than expected.
I/Q Raw Recording
Audio Sample

I've only seen this in rural South Carolina. The signal spans from approx. 885.3 to 889.7 MHzMegaHertz (MHz) 10^6 Hz. Here's a 1m2s IQ sample I recorded.

Edit by Tsalisbury0: This would be a UMTS 3G / HSPA+ 3.5G signal based on a W-CDMACode Division Multiple Access format... This type of 3G/3.5G is used by AT&T or T-Mobile.
