Can you identify this? It appears to be an ID within a waterfall display, which displays colors to represent amplitude across a spectrum of frequency.
As I look at it, it appears to say VE1HBV. I also saw one earlier with a US callsign that I can’t recall now. It must be well-known or experimental among seasoned digital hams, but I am new to the digital modes, so I have no idea what it is! Please, leave your comments if you have any information!
