If the "whooshing sound" you describe is coming from the second radio tuned around 1400, then it sounds like the Sentinal oscillator is working. If so, this would be a good place to use a signal tracer on the radio to be sure where the exact problem lies. A tracer can be rigged from an audio amplifier, like computer amplified speaker, with a shielded lead input terminating in a cap and germanium diode in series, for the RF portion of a radio.
