Hi there,
I'm new to GNURadio mailing list, so apologies if this question has been
asked/discussed before.
I'm interested in receiving AM radio signals. Here I have some
questions that hopefully someone will be able to answer me:
1. Since the frequency is not that high, I suppose it is enough to hook up
the antenna directly to the ADC?
2. If 1) is true, then is it still necessary to write software frequency
mixer to shift down the frequency to IF (around 455Khz)?
3. Which parts of the AM demodulation are already implemented in GNURadio?
Does it use envelope detection or synchronous detection?
Thank you so much for your answers. Right now I'm compiling Qt from
sources in order to compile GNURadio... Hope it won't be too hard to
compile... :)
