If it was an "AM" (i.e. mediumwave) radio, the signal would have
been between _850_ and _900_ kHz....

What you probably heard was either an _image_ or an intermodulation
product between the VOA signal and some other signal (combining
and forming sum and difference frequencies, one of which just
happens to fall in the mediumwave band).

Remember too that there are powerful VOA transmitters at Dixon, CA
which is relatively close to Sacramento and the Bay Area.
