Container-5 signal transmitter

The Container-5 signal transmitter enables James Mowry to reach a Terran communications operator from Jaimec, but not by an immediate point-to-point call. Mowry must set the tall cylinder in motion, let it signal for nearly three hours, and wait for a return connection before he can speak. The delay makes the device’s physical operation part of the communication itself: the transmitter sends its call outward while its user can do nothing but wait for an answer.

Form and Activation

As darkness falls, Mowry rolls the transmitter out through the mouth of a cave and upends it on a tiny beach. The device is a tall, silver-gray cylinder, pointed toward the stars. He removes a small handle clipped to its side, fits it into a hole in a slight blister near the base, and winds it vigorously. Something inside begins a smooth, steady “zuum-zuum.”

Mowry then removes the top cap, stretching onto his tiptoes to reach it, and sits on a nearby rock. The sequence presents the transmitter as equipment that requires bodily effort and deliberate setup, not as an instantly available channel. Its place on the beach, outside the cave, also leaves Mowry waiting beside an operating machine whose reach extends beyond the immediate scene.

Signal and Waiting

After warming up, the cylinder gives a sharp click, and its hum drops to a deeper note. Mowry understands that it is now calling into space in “soundless words” more penetrating than spoken language. Its pulse is rendered as “Whirrup-dzzt-pam! Whirrup-dzzt-pam!” and the message identifies its origin: “Jaimec calling! Jaimec calling!” The repeated call is the transmitter’s first communicative act in the scene; it announces a location rather than delivering Mowry’s report directly to Terra.

The signal is not directed straight to Terra. It must pass across frequencies, where it can be held while messages travel back and forth, and Mowry has to wait his turn. Nearly three hours pass while the cylinder remains on the pebble beach, continuing its scarcely audible hum. That interval makes communication dependent on a larger exchange already in progress: the device can issue its call, but Mowry cannot choose when a response will arrive.

Return Connection and Use

The first visible sign of a reply is a tiny red light near the top of the cylinder, glowing steadily. Mowry stretches up again, curses his shortness, and reaches into the open top to remove an object that looks exactly like an ordinary telephone. He holds it to his ear and identifies himself: “JM on Jaimec.” The transmitter thus supplies not only an outward signal but also a point of access through which he can hear and answer the returning communication.

A few minutes later, a voice comes back sounding as though it is speaking through gravel. Despite the distortion, Mowry recognizes it as a Terran voice speaking the familiar Terran language. The operator says, “Ready to tape your report. Fire away.” The exchange confirms that the long wait has produced a usable connection and that Mowry’s next task is to report, rather than simply to announce his presence.

The handset’s connecting cord is too short for Mowry to sit down while talking, so he has to stand. This small restriction grounds the distant, almost astronomical scale of the contact in an awkward physical detail: even after the signal reaches a Terran listener, the conversation remains tethered to the cylinder and its cord. The transmitter’s scene therefore moves from solitary operation to an audible exchange, but not to effortless communication. Its hum, delayed light, telephone-like receiver, and restrictive lead make the link tangible as a process with material limits and a waiting user.
