Make approximate adjustment of the antenna inductance switches, setting them at a higher rather than a lower wavelength than is expected. Using both hands, simultaneously rotate the grid and plate variometer dials over the entire scales. The dials should be rotated so as to keep the circuits on the verge of oscillating. When the desired signal has been located on the grid variometer dial rotate the coupler dial toward zero until the signal is. barely audible and then adjust the primary circuit. Make a final adjustment on the Coupler dial. Tuning Method for Two Circuit Receivers THE tuning of this type of receiver is more simple than the three circuit type. Maximum signal is obtained only when the wavelength control circuit is adjusted to the same wavelength as the desired signal, and the tickler is adjusted to the point of greatest amplification. Tuning for Signals of Known Wavelength Set the inductance switch for the desired wavelength range. Set the condenser dial to the position corresponding to the wavelength desired. Starting at zero gradually increase the Tickler dial reading to a position just below the oscillating point. (The oscillating condition is indicated by a soft hissing sounds in the telephones.) The desired signal should now be audible in the telephones and final adjustments may be made with the tangent wheel verniers. Flexible Armored Cable Tuning for Signals of Unknown Wavelength Set the inductance switch in the position corresponding to the range in which the signal is expected. Using both hands simultaneously adjust the condenser and tickler dials over the entire range, maintaining the proportion necessary to keep the receiver on the verge of the oscillating condition. If the signal oc...
