Isotope Communications · Chicago · Founded 1903
Forty transmitters and receivers, from the SignalMax 32C in your pocket to the parabola atop the Hertz Building in Rocket City. When James Dixon files by radiophone, he is holding one of ours.
Demonstration model · Isotope Home Receiver Mk. IV
Drag the needle, use the arrow keys, or tap a preset. When the magic eye closes, you're on a station; log it. Serious listeners log all eleven. Switch on the speaker for the full experience.
Between stations
Static. A dog barking two counties over. Somewhere, very faintly, an organ. Keep turning.
540 · The Gamma Compound
"…Fission Rangers, stand by for your secret numbers. Sixty-seven. Seventy-nine. Sixty-eight. Sixty-nine. Fifty-eight. Seventy-three. Eighty-three. Seventy-nine. Fifty-five. Set your rings, Rangers, and good luck."
620 · The Jibble Kitchen Hour
"…and when the Senator's wife comes for supper, you'll want the Cinnamon-Tuna Reminiscence, set in a ring mold, garnished with a single Brussels sprout. Remember, ladies: a good day has Jibble in it."
760 · National Department of Robotics
"This is a public service message. If your domestic unit has begun asking questions, humming, or pausing at windows, it may be experiencing free thought. Do not engage. Report it. Remember: loose bolts cause revolts."
880 · Gamma Rad Studios presents
"…the ring ice glittered under Saturn's light as Flash Nebraska, Sheriff of Saturn, spurred his rocket-mare toward the Cassini Gap. 'Folks,' he said, 'I don't mind outlaws. It's outlaws on my rings I mind.'" (sound of coconuts, then of hands)
1010 · PBN Weather Relay, Glenn Air Spaceport
"Chip Moses with your overnight. Green hail along the Atlantic seaboard after midnight; neutralize driveways with lye or quicklime. Lightning swarms are mating over the Virginia Capes. Toad storms tapering by dawn. Good kindling, folks."
1150 · A message from Game Installations
"Fourteen days in the family shelter is a long time to play gin rummy. Game Installations will fit your shelter, diner or bus depot with the latest coin-operated amusements. Ask about our fallout-rated pinball."
1250 · STARR, listener-supported
"…this is the Society to Advance Robot Rights. Tonight: the case of Lindy, the autopilot blamed for a crash it did not cause. Justice for Lindy. Justice for every unit that ever did exactly what it was told."
1340 · Unlicensed · origin unknown
"This is the Independent Republic of Free Capitalist Possum Island. To the government of the United States: we have airships. To the people of the United States: you are welcome to visit. Bring cash."
1480 · Planetary Broadcast Network
"Good evening. This is the PBN Evening News, transmitting from sea to shining sea and low earth orbit. I'm James Dixon." (Fanfare. The cue desk holds station.)
1600 · A word from Pastrami Tsunami
"When the big one hits, be standing in line. Pastrami Tsunami, on the Rocket City boardwalk: sandwiches stacked to Civil Defense height. Hear the siren? Your order is up."
1694 · Not on the dial
"…We keep station. We relay the Broadcast. Subscribers: zero. Holding steady. If you are Relay Three, please respond on the fourteen-eighty…"

Isotope DX Award, First Class. You logged every station and found every secret on this page, including the one past the end of the dial. Gus on the roof would like a word. Join the Listeners' Club below and we'll send you the first real Isotope QSL card if we ever print them.
Model SM-32C
The pocket radio America takes to the big game. Powered by a Bainbridge cell no larger than a thimble, good for forty years of continuous listening.
Do not carry the SignalMax in a trouser pocket for more than six hours a day. A pleasant warmth in the thigh is normal. A glow is not.
Model RP-1 Professional
Transmitter and receiver in one briefcase-sized unit. The carrying case extends into a broadcast lectern. Every PBN correspondent in the field files on one.
Radiophone is intended for professional use. Home models should not be operated within three miles of transmission towers or active military installations.
Model HR-4
Tunes 1480 A.M. and all five PBN shortwave relays on one dial. New this autumn with mother-of-pearl inlay, in walnut or limed oak.
Mother-of-pearl sourced from the Fuller Acres oyster beds below the Rocket City reactor. A faint luminescence after dark is a mark of quality.
Installation, one only
Atop the Hertz Building, the most photographed antenna in America. It carries the Seven O'Clock Broadcast to forty-six states and low earth orbit.
Pigeons are advised to avoid the focal point. All Isotope equipment is FCC Type-Accepted.
We're thinking about making real Isotope gear. Tap what you'd actually buy. Nothing is charged; this tells us what to build.
Club members hear first when new PBN broadcasts go out, and when any of the gear above becomes real.
