Also have SDR here. Interestingly the issue I found is you do need a good fast PC or packets will get lost.  I use a quad core Phenom with 8GB and it still loses data as it's highest sample rate  resoldering USB helped somewhat.  

I have a Tektronix 015-040 5mV/mA CT if someone has a use with pigtail lead and screw end. Has non standard fitting
