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.
