I don't want to be human! I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter ...
I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me.

What about directivity?

- Wed Oct 22, 2014 3:43 am #1826 I hooked up the ESP to my Spectrum Analyzer this morning.

Sorry for the Cellphone Pics , but I couldn't find a CF Card for the SA

Thats the ESP running at Wifi Channel 6 (2437MHz) , connected to my AP (~50cm away)



For comparison here is the same setup but with the ESP unpowered , my AP @ Ch6 is still quite visible.



Quite a lot of spurs from the ESP and the occupied BW is also not that good.

So anyone considering using the ESP in a commercial setup should think, imho, a bit about using an external bandpass filter ... and good luck for the FCC approval
