Yes, I see and hear it too, but it rarely affects copy. I credit MMTTY
and RiTTY by K6STI for their advanced filtering techniques. In the old
days of 88 mHy toroid-based detectors, 850 Hz shift and mechanical
printers it might have been worse but I don't know, I wasn't there.

And besides, if it was easy, what would be the fun when you finally do
it?
