I really don't see why you have a problem. All the bandspread cap does is finetune a space around the center freq. To use it correctly, you leave it set at 50, and then you can finetune either up or down. The stringing will only affect which side is up or down. Obviously, you want less than 50 to be down, so string it so it gains capacitance (lowers frequency) as you tune down. I think you don't understand the function of bandspread. Even though this is not a calibrated bandspread it does have definite position it must be in for the main dial to be calibratable. For most Hallicrafters receivers that is 0 on the dial representing minimum capacitance for the band spread capacitor. The main dial will not calibrate at any other value of capacitance. The trouble is that you are suggesting a sort of makeshift which would prevent the radio from working properly. The question is why was the capacitor made in such a way that it could not work properly if the dial stringing instructions for the receiver were followed and why some receivers of this model are one way and some another. Tha last two questions are probably beyond answering. Its possible that some person wanted the bandspread dial to start at 100 as it does for other brands of receivers and delibrately changed the position of the stop peg on the capacitor so that it rotates the wrong way. Its also possible there was some change made in production although I doubt that. In any case, since I have been unable to knock the peg out to replace it the other way. I will restring the dial system to reverse the rotation of the band spread capacitor. That will have the cap at minimum value when the dial indicates zero. The dial says on it to set at 0. So, even though I could simply calibrate it with the dial at 100 the markings would mislead someone else trying to use it. While makeshifts are sometimes necessary I really hate having to use them. Even the crossed stringing is a makeshift but I am afraid of damaging the capacitor and making the whole thing unusable if I apply too much force in trying to remove the stop peg. -- -- Richard Knoppow Los Angeles WB6KBL |
