Period

THIS TYPE OF RECEIVER USED 1922+

Canada

THIS ONE TUBE REGENERATIVE RECEIVER WAS PROBABLY NORTHERN ELECTRIC'S FIRST DOMESTIC RECEIVER. THE PARENT COMPANY, AT&T, HAD AGREED WITH RCA NOT TO PRODUCE RECEIVERS, SO THERE ARE NO U.S. COUNTERPARTS TO THESE RADIOS. (REF. 1)

Function

TO DETECT RADIO SIGNALS.

Technical

REGENERATIVE RADIO RECEIVERS WERE DEVELOPED IN THE EARLY 1920S, AS AN ALTERNATIVE TOCRYSTAL 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)
