“Personally, I don’t blame you a bit,” said Bob. “We can’t expect you to be a mind reader.”

“Well, then, that’s settled; so let’s look at the rest of the station,” said the operator, whose name was Bert Thompson. “This is our transmitter panel over here. It is very compact, as you can see for yourselves.”

He opened two doors at the front, one at the bottom, and raised the cover, thus exposing most of the interior mechanism to view.

“Here are all the fuse blocks down at the bottom, you see,” Thompson continued. “The various switches are conveniently arranged where you can easily get at them while you are sitting in front of the panel. Then up here are the microphones, with their coils and wiring where you can easily get at them for inspection or repairs. Rather a neat lay-out, don’t you think?”

“No doubt of it!” exclaimed Bob, admiringly. “We’ve never made a CW transmitting set yet, but we hope to some day. A set like this would cost a pile of money, even if you made it yourself.”

“Rather so,” admitted the young operator. “It takes a rich old fellow like Uncle Sam to pony up for a set like that.”

“We’re more interested in receiving sets just at present,” said Joe. “Let’s take a look at that end of the outfit.”

“Anything you like,” said Thompson, readily. “That panel is located on this side of the room.”

“I suppose you use a regenerative circuit, don’t you?” asked Bob.

“Oh, yes,” answered the other. “That helps out a lot in increasing the strength of the incoming sounds.”
