YASI — Amateur Radio Interferometry

Wow. This is just too cool. I got my TenTec 1056 receiver kit in the mail the other day, and was just randomly searching for links on the internet giving people’s experiences with it, when I ran across this:


This website describes the construction of an amateur radio interferometer using equipment that isn’t much beyond the budgets of other typical hobby activities. In particular, the “poor man’s version” uses two of the TenTec receivers that I bought, each wired to a common local oscillator. This enables them to correlate the signals from two widely separated antennas, and thereby determine the direction of radio sources in the sky.

It’s a fascinating project. Very cool. I’ll be back to read more later.
