Given the question: I know that the answer to the question "What was the odd discovery about the range?" is in "Initially, the station's range was officially a 40 kilometres radius of the Alexandra Palace transmitterin practice, however, transmissions could be picked up a good deal further away, and on one occasion in 1938 were picked up by engineers at RCA in New York, who were experimenting with a British television set.". Can you tell me what it is?
The answer is:
picked up by engineers at RCA in New York, who were experimenting with a British television set
