tracer gain for a suitable reading. The approximate af frequency markings for I he AUDIO FREQ. control may be spotted by hetrodyning the output against a borrowed audio generator, or a frequency test record on the Hi-Fi svstem, m

A typical application for the Gentrac in aligning a communications receiver is as follows:

1) if Alignment—Generator Mode switch to LF and 455 kHz crystal in LF socket* af Mode switch to "MOD". AUDIO FREQ. control at .4 (400 Hz), Connect generator output cable to converter stage grid, and tracer input lead to receiver audio output. Tracer input switches to Low Impedance and Low Gain. Tracer output set to VU, Set generator output and tracer input controls for suitable VU
