The use of the separateheterodyne permits the receiver to be tunedexactly to the wave. The beat note is ob-tained by throwing the heterodyne slightlyabove or below the signal it is desired to re-ceive. Both circuits should be calibrated foreasy manipulation. As this method of recep-tion is designed for long waves, honeycombcoils or other good compact inductances arerecommended.
