1930s Stewart-Warner Tombstone Radio need help identifying model number
#29

Hi Levi, here’s just a thought. Most radios run the oscillator higher than the dial setting. Say you set your radio to 1000khz on the dial, then your oscillator would be running at 1000khz + the IF frequency of 177.5khz or 1177.5 kHz in this case. If your oscillator erroneously got tuned lower than the dial setting instead of the usual higher value, that could explain you getting your local stations far from where they should be on the dial. The easiest and quickest way to check your radio is by using a portable held near the one you’re working on and see if you can pickup what frequency the radio is running at. If you set the radio dial to 1000khz you should be able to pickup the oscillator on the portable around 1177.5 to confirm its running where it needs to be! Something that’s quick and easy to do!
