I’ve been going crazy trying to track down an interfering signal that showed up recently on my FLDIGI waterfall.
Finally, I connected the RSP1A to the antenna and lo and behold, there was nothing there! It had to be something with the radio. Not only that, but it was there when changing the frequency and band … never moving on the display.
What could it be? DING DING DING !!!!! Operator ERROR!
Somehow I had fat-fingered the Notch on the IC-7300. Don’t remember doing it, but I sure did! Deselect the Notch and back to normal..
