    I am interested in increasing the distance that the IR in my universal remote can reach. I have done a little bit of reading on the subject and I see that remotes tend to use a signal somewhere in the 32KHz to 40KHz range.

    I don't think anything above 40KHz would work because the T.V. probably wouldn't accept the signal so I am wondering how I would go about increasing the distance my 32KHz signal can go.

    Any ideas?

    Hi John,

    You can increase the IR range by building a simple IR repeater; you
    point the remote at the receiver of the repeater, and the repeater in
    turn (via a cable)can then reach as far as you need. An added
    advantage is that the final equipment you need to control does not
    even have to be in line-of-sight.

    If you are interseted I could send you the schematics to build one.
