The limitation of 64MHz lowest input frequency is a result of the E4000
tuner, not of the oscillator. So no, it is not possible to receive the
low frequency short wave bands that you have indicated, sorry.
Also, I'm not sure what kind of signals you would find on those bands
which would require the 1MHz band-width of the OsmoSDR. Typically the
signals there are quite narrow-band, i.e. much simpler receiver design.
Regards,
Harald
