I just had my Philco 39-31XF chassis restored. No static where restoration took place about 90 miles from my home. Of course they had all the proper equipment and antennas to make the repair and conduct appropriate tests!! Now I am getting a static hum on most stations. Of course the antenna for this radio is a 10 gauge copper wire that is stapled to the perimeter of the box, in a loop fashion, but I have only temporarily placed a wire on the antenna screw and run it up the inside house wall. What should I do to improve the reception and get rid of the hum?? Should I run a longer wire outside to the top of the roof and attach it to a metal rod?? Next to the antenna screw is a ground screw. Does a wire have to be attached to the ground as well for better reception? Please help!!
