Hello all;

I am an undergraduate Engineering student and a SWL. I have tracked many
Amateur satellites from COEP Ground station, VU2COE.

I want to Home brew a NOAA satellite image receiver as my academic project.
I will be using WXtoImg to decode the image transmitted by NOAA satellite
on APT frequency. So the task for me is to get the audio frequency output.

Literature says that NOAA satellites transmit a signal of 40 kHz bandwidth.
I have also observed the spectrum on Spectrum analyzer using my antenna.
Want to know whether this is only RF bandwidth? and if it is so, then what
is IF bandwidth of such signals?

Can anyone help us in designing the receiver?
