Hello, I assume the switch is good. To be sure, when you turn the radio on, is the first selection the AM selection and the second position the police? Well, with the waveband switch in the first position- Here's what's new to me: I put a modulated signal of 1400 kc from my signal generator right to the antenna post, tune radio to 1400kc also, and it "kicks" into oscillation and the radio works great! Sometimes! Sometimes if I tune it below 1000 kc it will die. Put the 1400 kc modulated signal back to antenna, tune back to 1400 on radio, it works great. I think I have a weak RF or oscillator tube. Again, my RF and oscillator coils check out with an ohm meter. It gets a jolt from my generator, works good! Turn off radio, turn it back on, static, until I apply the modulated signal again. Any suggestions? Thanks!
