Specific AM radio frequency software source

Question

I am interested in Software Defined Radio. I have practically no experience in any subject of electrical engineering or mathematics, but I read ...

Instead of trying to figure out the hardware aspect of the antenna and ADC, I think it would be fun (and cheaper) to play with some pre-recorded (or even live!) Model streams of the AM band.

From what I have learned so far, it seems to me that the AM format will be easiest to decipher - a narrow bandwidth / window function over the entire spectrum to obtain any target frequency, then a short average average conversion (?) To get a different sample amplitude / sample to receive an audio signal.

For a full North American AM group, it seems to me that the uncompressed stream will be:

1606.5 kilobytes x 2 (twice the frequency for samples) x 2 (16-bit samples) = 6.28 megabytes per second

It is probably clear that I will spend money on equipment at this stage ... Are there any sources for the AM group? Or other best ideas for hands-on training?

You should talk to GNU Radio , or at least look at their code. They are engaged in software development and must have samples for testing modules.
