The signal generator output should at all times be just sufficient to obtain a minimum deflection on the output meter. Set the signal generator to 456 kc and adjust the i-f trimmers for maxi mum meter deflection in the following sequence: L4, L3, L2, L1. Set the generator and receiver to 1600 kc and adjust the oscillator trimmer c4 for maximum output. Set the generator and receiver to 1400 kc and ad just the loop trimmer C3 for maximum output.
