Perhaps the accompanying diagram makesthe foregoing description clearer. It will be noted that thearrangement here shown is very mUch like the usual regen-erative receiving hook-up, except that the telephone re-ceivers have been left out, and a telegraph key is placedin the primary circuit of the oscillation transformer or -S-B. rr vc, n G Simple CW telegraph transmitter whichmay be assembled by any one.

Thiscauses the wave length to fluctuate, and produced the dotsand dashes in the sharply tuned continuous waves inter-cepted at the receiving end. The experimenter is practically limited to the vacuumtube for his experiments and work with undamped wavesbecause of the cost and other deterrent features of other
