But what if I extend the range of my keyboard. Could others tune in and capture my passwords etc? Good idea. But what if I extend the range of my keyboard.

All depend on how to implement! About MA6221, you can see MA60H22 (earlier generation) fully compatible Pin to Pin with MA6221. Excellent article, really up range to 4 m, in chinesess, but it is understandable in principle, over here http://pc01.lib.ntust.edu.tw:1793/ETD-db/ETD-search/getfile?URN=etd-0721107-170305&filename=etd-0721107-170305.pdf Hi All,

The best guess that I could make is that the exact position of the new antenna changes the directionality of the antenna and thereby the coupling between your transmitter and receiver. Hi Haley,

If it is a windows system and you plug in the receiver, you should see a system message that it found new hardware and is eventually ready for use. If you don't see that, try checking the hardware manager under control panel->system. Finally, to get the devices to sync up, you press the learn button on the receiver and then the small red button on the mouse or keyboard while they are very close to each other. Let me know if this is useful or if you need further information. Hi Amanda,

I just received the "ma6221-s7k" from a friend for free (just the right price!), and I have no idea how to get it to work on my in-laws' pc. All she gave me was the mouse and the adapter, so I had one hell of a time taking it apart to find out what it was. Mosart? Got any site for drivers? Or anything at all about this crazy thing? lol I don't read Chinese, so I'm screwed! Much appreciated! Amanda Hi Nico!

I just used it myself and I am very pleased with the results. I did it a little more ghetto but it's still just what i needed. Thanks for the idea :) Awesome Idea!
