(5962 same-band-wrong-freq spots + 885 wrong-band spots) / 175584 spots 
total = 3.89955% bogus-frequency spots.

The spurious responses of SDRs also appear in their recordings, so root 
issue has potential to touch those who have nothing to do with RBN 
during contests - especially if claim this is all to do with fecal 
signals gets any traction.
