While recovering from my brief outpatient procedure yesterday, I was surfing around, looking for the ChirpHell and ChirpPix programs that some people mentioned in the context of creating the Hellschreiber IDs that I saw yesterday. A bit of Googling revealed that they were written by DF6NM, so I did some more websearching, and as soon as I found this page:
I forgot entirely about ChirpPix. This page is all about using the reflections from the NavSpaSpur radar fence to generate actual pictures of the moon. Very, very neat. I should think about this, it seems like a very nifty project.
He also seems to have done some interesting work in the LF spectrum.
