Dream d1303-s: What Keeps Transmitting

I had a dream where...

I had a dream where the Listener stopped walking before any instrument showed a reason. She raised one hand - a flat palm facing back at the column of us - and we all stopped, eight people and one small dog in a line along the cable trench.

"There," she said. "Under the hill."

The hill was unremarkable. Scrub grass, a rusted conduit collar half-buried in the slope, the kind of hardware that appears in the margins of old survey sketches. But she heard something in it.

"Forty-seven megahertz," the Listener said. "Give or take. Someone's carrier wave is still running."

The Weather Reader pulled his tablet and checked atmospheric interference - old habit, competitive habit. "Not atmospheric," he said, after a moment, with the tone of someone conceding a point he had not wanted to concede.

The Builder crouched at the conduit collar and brushed dirt from its flange. "Pre-settlement infrastructure," she said. "Look at the threading pattern. Nobody's tapped this in at least two generations."

The Philosopher, pulling the library wagon up the slope with the Student's help, called from behind: "Are we prepared to define 'nobody'? Because the signal running through it suggests someone."

"Or something," the Weather Reader said.

"A carrier wave doesn't constitute intention," the Philosopher replied.

"Neither does a weather system," the Listener said pleasantly, "and yet here we are, following yours."

Lano trotted to the base of the hill, nose pressed flat along the conduit line, ears rotating like small satellite dishes. He stopped at a concrete hatch half-hidden by grass and sat down with great decisiveness.

"Encontrado," he said.

The hatch opened on a maintenance node - a narrow room of racks and panels, indicator lights cycling green and amber on backup power, a transmission array still broadcasting on the old frequency bands. The air tasted of decades: warm electronics, mineral cold from the cave wall behind the racks, something that might be solder or might be stone.

The Dreamer raised his camera immediately. The Student began reading the panel labels aloud, slowly, as though translating a language he almost knew. The Wireman moved to the main rack without speaking and touched the panels the way he touched everything - like he was listening through his hands.

"It's cycling a beacon pattern," the Listener said. She plugged her headset directly into an auxiliary jack. Her expression changed. "Not ours."

"How old?" I asked.

She took off the headset and held it out to me. The signal came through as a rhythm - not quite regular, not quite random, something between.

"Old enough," she said, "that whoever built this was asking the same question we are."

Outside through the hatch, the sky was perfectly clear. The signal hummed in it without apology, patient, still broadcasting on a frequency nobody had been scheduled to receive.
