Bandspread vs range continued from previous post

If you observed the effects of adjusting the Vcap ratio by adjusting the low end capacitance and the high end by adjusting the "trimmer" It should be easy to understand the importance of making the adjustments in order. The 600KC adjustment sets the bandwith while centering the range over the correct dial point. The 1400KC adjustment sets the high scale to the correct point. You must work between the two to get the proper operation of the set. Both effect both ends of the scale so the 1400KC could be adjusted without first setting the 600KC and then you are looping back and forth with to wide a band. You can set the dial to 1400KC and adjust either one adding the low range adjustment while reducing the high range adjustment and hold the output steady. Anywho here are a couple of excert from the service manual.
