FM Walkie-Talkie (Aug, 1950)
I thought that a walkie talkie implied something you could carry, not strap on your back and lug around.
FM Walkie-Talkie just announced by Motorola, Inc., of Chicago, 111., will be popular among law enforcement agencies, fire protection departments, forestry services, railroads, etc. It has 24 tubes and weighs 19 lbs. A tip-up loudspeaker broadcasts over the operator’s shoulder or to nearby listeners. It has a range of from five to seven miles, depending upon altitude and presence of physical obstructions.
“Carryphone” Aids Trainmen (Apr, 1947)
Wow! Look how portable and convenient it is!
“Carryphone” Aids Trainmen
Engineers and trainmen can keep in constant touch with their own crews or talk with the crews of other trains with the “Carry-phone,” a portable telephone announced by the Pennsylvania Railroad. The device uses railroad tracks or wires as its communication channels, but transmits and receives messages through the air by induction, using a large metal loop.
RCA Radiotron (Oct, 1927)
This is some brilliant marketing here. Other brands of radio tubes may be as good as Radiotron, and yeah they may be cheaper, but that just means we’re the standard.
Ok, but why shouldn’t I buy the cheaper ones again?
From time to time other tubes will be offered to you as being “as good as Radiotrons,” sometimes at a lower price. Which proves that the Radiotron is the acknowledged standard in performance.
The American people have used millions of Radiotrons in the last five years. Is it reasonable to suppose that imitators could give you Radiotron quality for the same money?
Racing Time For News Scoops (Apr, 1935)
Very interesting article about how the UPI used to report and distribute news. I’ll bet their operation ran a lot like this up untill about the 70′s when computers started taking over.
Racing Time For News Scoops
By ROBERT L. FREY
Executive Assistant United Press Associations
NEWS travels fast. It circles the globe like lightning while historic events are still in the making.
The world was reading the tragic details of the Morro Castle disaster while her passengers were still leaping from the burning decks of the doomed Ward Liner into the storm-swept waters of the Atlantic.
Less than 20 minutes after first radio operator Rogers sent his SOS from the Morro Castle, the tragic story was flashed over United Press leased wires into newspaper offices from coast to coast. Cables carried it to Europe, South America and the Orient.
Portable Army Radio Tested (Nov, 1937)
It looks like you should be able to wind up that key in his back and make him march.
