Context

Period: THIS TYPE OF RECEIVER USED 1926+
Canada: Unknown
Function: TO DETECT AND AMPLIFY RADIO SIGNALS.
Technical: REGENERATIVE RADIO RECEIVERS WERE DEVELOPED IN THE EARLY 1920S, AS AN ALTERNATIVE TO CRYSTAL SETS. REGENERATIVE SETS EMPLOYED A VACUUM TUBE TO BOTH DEMODULATE OR DETECT THE RADIO SIGNAL, AND TO PROVIDE AMPLIFICATION. CAREFUL CONTROL OF THE LEVEL OF AMPLIFICATION WAS NECESSARY TO PREVENT OSCILLATION OF THE VACUUM TUBE BUT THE RESULT WAS THAT POWER OUTPUT WAS INSUFFICIENT TO DRIVE A LOUDSPEAKER. (REF. 1)
Area Notes: Unknown
