You should have heard 75 in the late 50, early 60s. That is when you had
wall to wall carriers and assorted hetrodynes from 3.8 to 4.0 every single
night until wee hours of the AM.

I do remember that, vaguely. Isn't that the era when every good receiver had a
slot filter, notch filter, or Q-Multiplier reject filter? These lasted thru
the transition era from AM to SSB, when the sidewinders really had to suffer
those hets!
