They make millions of tuner/decoders for consumer devices (TVs,PVRs, etc).
They probably make modulators by the thousands.  Mainly needed by TV
broadcasters and cable companies.  Totally different production
quantities.  The modulator probably also has to be much more precise
since it is generating signals, not receiving.
