Yes Plith, some radios (early) don't go above 1500. Hard to tell from your video but you have to have the signal from your sig gen hooked up right. The high side to the antenna and the ground on the radio chassis. Modulator turned on. Just set the sig generator somewhere on the middle of the AM dial and scan your radio to see if you can find that sweet and annoying tone. If no joy, you may not have the oscillator on your radio working. Glad to see you passed the first test.
