I finally managed to record some video, with my Canon SX-230, of the Hi-Per Mite Active Audio CW Filter. I had to delay filming by a week due to sinusitis, but this turned out for the best since the WPX yielded enough signals to show what this filter can do. I am more than happy with it and it is going to be a permanent part of my set up. Thanks to Larry (W2LJ) for mentioning this great filter here on this site. The only thing left is to find a case to build it in. This coming Saturday we are going up north to Taipei, so ample opportunity to get one. Enjoy the video.
