How do I know if my radio is AM or FM?
Find Your Local Station: With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
What should I look for in a transistor radio?
If you can identify which lead of a transistor is which, try testing the voltage between the base and the emitter, which should be around 0.3V for germanium types and 0.7V for silicon. There should be a greater voltage between the emitter and the collector, probably at least 1V and more likely several volts.
Which transistor is used in radio?
Raytheon 8-TP-1. In February 1955, the second transistor radio, the 8-TP-1, was introduced by Raytheon. It was a larger portable transistor radio, including an expansive four-inch speaker and four additional transistors (the TR-1 used only four). As a result, the sound quality was much better than the TR-1.
What is the difference between radio and transistor radio?
Modern radio circuits are transistor based circuit making the size of the radio device simple, small and energy efficient. Radio is a device which transmit and amplifies signals. The modern radio uses transistor since it is smaller in size. Transistor used for voltage as well as current amplification.
Which travels farther AM or FM?
Although AM waves can be received at greater distances than FM waves, FM. waves do have advantages. They are not affected by static as much as Am waves. Static is caused by electricity in the atmosphere.
What is the best frequency for an FM station?
If you want everyone to hear your broadcast, or at least as many people as possible, use the 88–108 MHz band, that’s where all the commercially made, personal radio receivers work and all the commercial broadcast radios work.
Can you communicate through a transistor radio?
It may be fixed on the PCB using wax. With a walkie- Takie, you may communicate 2 ways or as many ways as you wish, depending on the amount of people your converting with during one event. In 1954, Regency Electronics and Texas Instruments incorporated the transistor into the first portable transistor radio.
What is the use of transistor radio?
a radio receiver in which semiconductor devices, primarily transistors and semiconductor diodes, are used for the amplification, frequency conversion, and detection of signals.
How much did a radio cost in 1960?
The more modest radios were around $70– about $1,050 today. By the 1960s TV had already become the biggest home service. However, the portable transistor radio was all the rage and cost a premium for such a small piece of equipment. A Sony 8-channel transistor radio with batteries cost $49.95.
Which transistor is used in FM transmitter?
Best FM Transmitter using 2N3904 Transistor. This is the best circuit of an FM transmitter to broadcast your “voice or music” around the place.
What are the types of radio?
Types of Radios
- AM Radio. AM radio stands for amplitude modulation, and it’s one of the oldest types of wireless broadcasting.
- FM Radio. Many people who listen to the radio in their car listen to FM radio.
- Shortwave Radio.
- Satellite Radio.
- Ham Radio.
What are the stages of radio frequency?
These three ports are the radio frequency (RF) input, the local oscillator (LO) input, and the intermediate frequency (IF) output.
What is the best AM FM radio to buy?

Do radios use semiconductors?
Anything that’s computerized or uses radio waves depends on semiconductors. Today, most semiconductor chips and transistors are created with silicon. You may have heard expressions like “Silicon Valley” and the “silicon economy,” and that’s why — silicon is the heart of any electronic device.
Which company invented transistor radio in 1952?
Transistors were first produced commercially by the American company Raytheon, in 1952. The first radio to be produced commercially was the Regency TR-1, which was also manufactured in America and went on sale in November 1954. It only used four Texas Instruments transistors, as transistors were then very expensive.
