A CW transmitter is a simple affair; sometimes just the single crystal oscillator circuit itself can be used as a low-powered transmitter A voice transmitter, especially one that suppresses the carrier and one sideband requires quite a few more circuits.... and parts. A SSB rig can easily be built, but I doubt that it could be built profitably and still sold for $44.
If such a rig does become available at that price.... I'll buy three!
