Meantime Bob had finally got the set tuned to the proper wave length, and the little group were all delighted with the clarity and volume of the resultant sounds. They were not nearly as loud as an ordinary phonograph, but were sufficient to be heard distinctly in a fairly large room.
“It’s too bad we only have a one-stage amplifier,” said Bob. “If we only had another transformer and vacuum tube, we’d have a loud speaker that you could hear all over the hotel.”
“I think this one is plenty good enough,” asserted Edna.
Both she and her sister were as excited as children with a new toy, and they were both delighted with the music.
“You boys will have to bring this wonderful thing into the parlor tonight, and let everybody hear it,” coaxed Edna. “I know they will all be tickled to death to hear a concert in this new way.”
“They might not be as enthusiastic as you think,” said Bob, doubtfully. “Maybe they’d rather just talk, and wouldn’t thank us for interrupting them.”
“What an idea!” exclaimed Ruth. “Just try it once, just to please us, and you’ll soon find out whether they like it or not.”
“Well, if it’s to please you, we’ll certainly do that thing!” Bob gallantly remarked, and was rewarded by a friendly smile.
“Edna and I will speak to the manager about it this afternoon, and I know it will be all right,” she said. “We’ll tell you what he says at supper time.”
The radio boys, although they were radio enthusiasts themselves, did not actually realize how deeply interested people had become in this new and wonderful science. They were somewhat surprised, therefore, when the manager sought them out that afternoon and told them that he would be more than delighted to have them give a radio concert that evening.
