I am restoring a Firestone Firechief S-7428-2 MW radio. The schematic reflects a loop antenna or a long wire antenna. The unit I am working on is reflective a long wire antenna. My question is; the schematic does not show capacitor number 2 or resistor number 2 and installed components reflects same. Can someone be of some help here as to why? Was there a modification made not reflected on schematic? Or; is the long wire model different in the sense it does not require these two components? Thank you
