Re: rf modulator, what about transmitter?

["BruceR" <br@xxxxxxxxxxxxxxxx>]

I took it to mean broadcast over the air because he refers to the
following:
 - the term "actually transmitting"; In concert with the info below, I
took that term to mean "over the air."
 - at least a 10 ft range; range wouldn't be an issue with a wired
solution (at least not the lengths we'd be talking about on a boat).
 - the term "pick up" a signal; implies (again, to me) a wireless
signal.
 - no inputs other than, presumably, an antenna; leads me to conclude
wireless rather than a piece of coax wrapped around a rabbit ear.
 -refers to "similar things for FM"; small FM wireless transmitters are
very common (moreso than wired FM modulators) and I concluded he was
referring to those.
 Of course, all of this is based on MY conclusions and perhaps Bill will
clarify further. In any case, I think he now has a comprehensive
collection of options from which to choose.
