1、/sr /? / 3 PAMT ArJSSMTC. rWHnW j To calibrate receiver connect the output of signal generator to the flex* Ible antenna lead attached to the loop antenna. Connect the Iom aide of signal generator through a 1/10 mfd. condenser to receiver cheesi s.Ti*mts the wave trap condenser. Adjust signal genera

2、tor to HSb Kilocycles and adjust both I.F. transformers for maximum signal. Re-peak the wave trap condenser for minimum SSS K.C. signal. Osen the receiver variable condenser for minimum capacity. Set signal generator at 1700 Kilocycles. Peak oscillator section of receiver condenser for maximum signa

3、l. Next set signal generator at |500 Kilocycles. Tune in this signal. Adjust R. f. section of receiver variable condenser for maximum signs! strength. Keep the signal generator output as low as possible when making all of these measurements. rr I2ATC Itetc ItBAft I2IAR SOBS DeWald Radio Model D-616 TO 105-123 Z01Y3 1 60 OULY 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 RadioFans.CN
