DavidEduardo said:It's unlikely that there were sloppier front ends than the Asian imports my AM listeners had, predominantly, in the 60's. And I never heard of this being done. Don't you find that odd, particularly when I had rather well rated stations? I had to go to the duty free in Panamá or Miami to get a decent radio to use... and I went through 12 to 15 radios a year.
With you I find everything odd, including your choice of poorly designed AM radios from Asia in the 1960's. What were the "makes" of the radios?
In the US, we used brands like GE, RCA and Zenith. I know it's not Samsung, but we made it work.
