Interesting article. A pdf version of the East and Gancio paper referenced in the article at at [1]. Its also worth noting that they used a 30 meter dish, which is probably on the large side for amateur radio astronomy.

  Not if you exploit the stars gravitational lensing: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.188.1145&rep=rep1&type=pdf http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.188... A mobile phone antenna (and power) might be well enough then.

Before realizing this was on a site for the RTL-SDR software, I found it very odd that the author felt the need to define "Pulsar" but not "RTL-SDR". For those punching through without investigating, "RTL-SDR is a very cheap software defined radio that uses a DVB-T TV tuner dongle based on the RTL2832U chipset." So yea... this is pretty cool.
