I have a Yaesu FT-857D in my car. On trips I often slide down to the AM broadcast band. Here's the weird thing: I swear all the program hosts that I am familiar with, sound like different people. All the voices are slightly high in pitch. How can this be? This is AM not SSB! Is this some sort of DSP voodoo? Can this be fixed? It's driving me nuts.

The primary limitation on receive audio is the tiny speaker in the case. For any real use, it cries out for an external speaker !

And the AM filter is only 6kc wide in the 857, passing only up to 3000 hz.  Not exactly HIFI.

hi pitch is probably not the BW setting.

You could be in a SSB or AM mode with the IF shift set high.
