IF AMPLIFIER

IF amplifier consists of two-stage collector turned amplifiers using BC548. It provides useful gain for both transmit and receive modes. The coils used are of same type, wound on ordinary IFT core. Primary is 15 turns. Secondary is 4 turns. Any thin copper wire such as 36 SWG can be used. The IF amplifier can be turned by connecting carrier oscillator at input and RF Volt meter at output. Adjust both coils for maximum deflection in RF Volt meter.
