Unknown MFSKMultiple Frequency Shift-Keying?

"unknown 550 is most likely noise from the USBUpper Side Band Modulation (Radio, referring to reception and modulation mode)Universal Serial Bus (Computer, referring to USB Ports and cables) interface of a PC or noise from a monitor. I have seen a very similar signal and found it to be noise from the PC." someone verify this please? --Cartoonman (talk) 11:31, 2 November 2015 (NZDT)

"When i turn on my LCD TV, i see a interference very similar to "Unknown 550" Possible monitor interference. I have seen something similar to this myself. Would like a confirmation. --Cartoonman (talk) 09:19, 30 December 2015 (NZDT)
