I need help I have a old Hallicrafters SX-24 that the broadcast band coils, both osc and antenna coils are gone. For some reason the mice only got those 2 coils and the old set works pretty good on all the other bands so I would like to wind new coils and get the broadcast band working. My GDO does not have the BC band on it so its no help. I installed a universal osc coil that seem to work but I cant seem to get the ant coil right. I have used formulas on the web and get about the same number of turns for the windings. The coils are wound on 3/4" form, the tuning cap is 440 mmfd. with 4 mmfd of trim across it. I am using 34 gauge wire and the formulas I used says to use 130 turns for the secondary of the ant coil. I used about 50 turns for the input coil.
Any help or suggections would be appreciated. I also have the HT-9 transmitter and would like to get the 1939 station back on the air. Thanks Bill Fondren K5PML
