. QST . frequency of 3700 kc). This can be used as acheck point for the frequency alignment of receiver. With the crystal frequency known, ham-bandfrequencies can be determined quite accurately(if the calibration is correct) by simply addingthe frequency, given in the table,to the reading of the dial. Measurements with a signal generator showedthat recognizable audio output could be obtainedwith a signal input as low as /xv. Most of thebackground noise disappeared with the inputsignal raised to ^v., and solid reception waspossible with an input signal o

Measurements with a signal generator showedthat recognizable audio output could be obtainedwith a signal input as low as /xv. Most of thebackground noise disappeared with the inputsignal raised to ^v., and solid reception waspossible with an input signal of about fiv. The cost of a complete set of components forthis converter will run about $ The crystaland set of three coils required for each band runsabout $, so that the cost will be reduced bythis amount for each band that is not needed.
