Hi Dave.  Yes, I hope to build the transmitter portion to allow the
Ocelot to control the fans.  Right now, the Ocelot can do so by sending
IR to the hand-held remote control, using a small interface that Guy
designed.  But I hope to use one of those small transmitter modules to
free up the hand-held remote.

What I am really in need of, is the receiver which goes in the fan
housing and controls the fan/lights.  There are, of course, many
different ones available, but I would like to get one compatible with
the ones I already have, so they can all be (individually) controlled by
the same transmitter/protocol.

In searching the web, I've seen other ones which /look/ identical, but
not for sale in N. America.  I haven't had any luck with the
manufacturer, either.  If I can't find one that is compatible, perhaps I
will at least be able to find another one that uses the same frequency,
so that the same transmitter can be used, even if it means an additional
protocol.
