Pretty much the same as today, when you think about it.
The metalloids is combined in transistor radios to make them of high quality.

The farrari 250 gto is the most expensive car of the 1960s.
It was used to measure the strength of a laser. In the 1960s, razor blades were pretty much similar in shape and a Gillette was a non-standard unit for measuring the strength of a laser beam. The measurement comprised the number of laser blades that a laser device could burn through.

Commercial truck drivers do commonly used CB Radios. As for Cobra CB Radios, the commonness would depend on where the professional truck is and if the Cobra CB Radios are offered and popular in that location.
No, radio communications are not only used with 2 way radios. They can be picked up on many frequencies, that are not necessarily considered to be 2 way radios.
(Adam and Eve and the Titanic) Actually: Table top radios and Console radios used in the living rooms of peoples houses.
The radio has gone through many changes including a switch from analog to digital. The first digital radio was invented in the late 1960s.
Transistor radios have NO tubes. They have (guess what) transistors.
UHF radios are handheld radios. They are a great 2 way radio that are used by police, children, and hikers. They can be used by anyone needing to communicate via 2 way radio in the outdoors or indoors.
It is difficult to provide an exact number of radios in North Korea as data on this topic is restricted and not readily available. However, it is believed that radios are widely used for government-controlled broadcasts in the country.
Radios, television, toaster, record player, fridge, washing machine, ovens, mixer, fans, heaters, irons and sewing machines.
Marine band radios are two-way radios which are used either in a military setting or by officers for easy communication. The purpose of these radios is to get a greater range of communcation.
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
Cobra MicroTalk radios are two way radios or walkie talkies that allow you to keep in contact with someone a certain distance away without making a phone call.
