Just picked up a 1930s Battery operated Coronado

For example, if the Coronado's dial is at 550, its oscillator should be heard around 1010 on the other radio. Or if Coronado's at 1140, you should hear the osc at about 1600.

Well the strange thing is that the Coronado's tuner is set to around 640 AM and the tuner on my Panasonic RF-511 AM/FM transistor radio is set to about the same spot and that's where I hear the Coronado's Oscillator on the Transistor radio is at 640 AM on the dial or very close to that spot anyways and when I go up the dial the oscillator noise kind of dies off the higher up the dial the tuner goes (on both radios).

So I'm guessing my oscillator is working but not correctly...
