Suggest merge with Transponder, as this article describes an aspect of one. Might also be worth a mention at Code.--31dot 23:55, June 20, 2011 (UTC)

Oppose. While this IS something that is part of a transponder, not just something that you can do with one. It should be mentioned at code though. - Archduk3 00:09, June 21, 2011 (UTC)

Yeah, I agree(after some thought). Just removed it. ;)--31dot 00:09, June 21, 2011 (UTC)
