"Ralphie"/Jean Shepherd of WOR fame, the person who wrote and narrated the autobiographical movie "A Christmas Story", actually lived on Cleveland St. in Northwest Indiana, which would be 164th Street if extended into Chicago, not in Cleveland, OH. The address found online is about 3 miles from the WIND towers in Griffith, IN. It always seemed to me that he should have listened for his Ovaltine clues on a crystal radio. I'm sure he must have had one. Maybe he thought it was too geeky for a mainstream movie, and wanted to focus on the Red Rider BB gun type themes. I just calculated the field strength at the address on Cleveland St. The Night pattern field strength, which exceeds the Day field strength, is 280 mV/m, based on M-3 conductivity. That's definitely a crystal radio grade signal.
