got my PC generating rife frequencies, real cool

Anyways, after doing research and asking around, I found a great site called http://www.noriftrife.com that makes you create your own Rife frequency unit through your computer. It's very simple, you can generate any frequency you want with software out your computer sound card, then need a 200W stereo to amplify it, from the speaker out to electrodes for your wrists or TENS pads. Amazingly, I got it to work. I feel the sensation and electric waves when on. My father passed away 2 weeks ago, so I stopped doing anything, now I am more motivated to cure my Ulcerative Colitis. I tried the Ulcerative Colitis frequencies quite a few times and seem to have no effect. I have heard in previous forums people mentioning that most of the frequencies are out of date. Does anyone know exactly what frequency to use? I also heard of something called a Fscan2, that lets you know exactly what frequency will heal you. Any feedback is greatly appreciated.
