Does radio Shack sell transistor radios?
Great little transistor radio I’ve been using these radios from Radio Shack for about 15 years. They keep getting smaller, but they still work well. I live in a house that has interference from a TV antenna, and regular radios can’t tune in as well as this radio, and I kept these in several rooms.
What replaced the transistor radio?
By the 1970s and 1980s, the Walkman (see entry under 1970s— Music in volume 4) essentially replaced the transistor radio, due to its superior sound quality and ability to play cassette tapes.
Are transistor radios worth anything?
Today pocket transistor radios manufactured in the 1950s are very collectable. Some models are highly sought after by collectors and regularly sell for hundreds of dollars . It is not uncommon to find a transistor radio at a yard sale for $4 or $5 and sell it the next week for several hundred dollars.

Does Walmart sell transistors?

What is the range of a transistor radio?
So realistically, for two people carrying a handheld two-way radio, the maximum communication distance on flat ground with no obstructions is around 4 to 6 miles . So you may be wondering why you see radios that have range claims of 25 miles or higher.
What does a small transistor radio do?
The function of transistors in radios is straightforward. Sounds are recorded through a microphone and turned into electrical signals . Those signals travel through a circuit, and the transistor amplifies the signal, which is subsequently much louder when it reaches a speaker.
What caused RadioShack failure?
The company had too many stores that cannibalized revenues from each other and generated losses. RadioShack failed to adapt and stay relevant when most electronics sales shifted online, and the retailer was stuck in brick-and-mortar locations only.
Are transistor radios analog?
Larger transistor radios received FM broadcasts as well. Both AM and FM radio circuits were analog . Nowadays integrated circuits allow such complexity and speed and are so inexpensive that it is feasible to use digital methods to modulate and demodulate audio, so we are seeing digital radios.
Is RadioShack out of business?
Founded in 1921, RadioShack filed for bankruptcy twice between 2015 and 2017 , left in the dust by other electronics retailers like Best Buy Co. Inc. and Amazon.com Inc. The company now operates primarily as an online retailer but still has a network of about 400 stores owned by independent dealers.
How do you make a simple transistor radio?
Are any radios made in USA?
The 4th of July is a great time to celebrate our “Made In USA” products! Pacific Radio is a family-owned American company and for the past 82 years we have always believed in supporting American businesses and manufacturers.
Which company invented transistor radio?
Building on war-time research, John Bardeen and Walter Brattain , working with group leader William Shockley, developed a device they called a transistor. The first laboratory demonstration took place on 23 December 1947. Bell publicly announced the new invention on 30 June 1948.
When did small transistor radios come out?
In July 1954 the Texas Instruments and Industrial Development Engineering Associates (I.D.E.A.) companies embarked on a six month project to produce a pocket-sized radio for the Christmas market. The result was the Regency TR-1, the world’s first pocket transistor radio.
What year did the transistor radio come out?
When one thinks of the most significant dates in our technological development, October 18, 1954 doesn’t pop up there at the top of the list. It should; 60 years ago the first portable transistor radio went on sale.
When did portable transistor radios come out?
The Regency TR-1 hit stores on October 18, 1954 . It received AM stations and sold for $50, the equivalent of more than $400 today. Although a limited number of portable radios using vacuum tubes had been available, the TR-1 immediately transformed the state of consumer radio technology.
Why is it called a transistor?
The word transistor is a combination of transfer and resistance. This is because it transfers the resistance from one end of the device to the other end or we can say, transfer of resistance . Hence, the name transistor. Transistors have very high input resistance and very low output resistance.
What does a transistor do?
A transistor is a semiconductor device used to amplify or switch electrical signals and power . The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.
How far will a 5 watt UHF radio transmit?
So according to our rule-of-thumb, 2 people around 6 feet tall using a 5 watt handheld two-way radio, used on flat ground with no obstacles, will have a maximum range of approximately 6 miles .
How far can a 10 meter radio transmit?
Go here for in depth propagation information. Ground Wave (How far can I transmit?) Ten meter ground wave (direct) propagation is much more predictable than “sky wave”. Local contacts up to 40 or 50 miles or more can be expected 24 hours a day and is very useful for local communication.
