Wide signal at 443.5 MHz
From Signal Identification Wiki
I have no idea what this is. It may be interference since it jumps around and sometimes disappears. My 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. ZIP was under 16 MB, but sigidwiki still had trouble. Here is a link to it on Google Drive.
