It is. I bought one, and it works great. I built the "$200 Radio
Telescope" described in that article, with the addition of some 1.4 GHz IF
gain and filtering (I used the AmpliFilter described at
<> between the LNB and the
meter), and was actually able to detect the full moon (but no other phase).
Theoretical calculations suggest a 75 Jansky threshold sensitivity for
that system with 1 second of integration time, although I have not yet
measured any of the distant sources. Sun noise, OTOH, is trivially easy!
