Hi Marcus,
Very nice. We've also been looking at using the $8 RTLSDR as a
educational tool to do exactly the same thing.
Alan Rogers et. al. at Haystack have also developed something similar:

Yes, I'd seen both this, and the earlier SRT.
This new SRT is still about, I'm guessing, a factor of 5 more expensive
than my approach :) Although their instrument will be more sensitive, due
to the larger collecting area, althouth their claimed Tsys (170K,
really that high?) is a bit of a worry...
