Review E JOHNSON 140 Pf Variable Capacitor Transistor Ham Crystal Radio Project

The Johnson 140 pF Capacitor Transistor is a crucial component in the world of Ham Radio and crystal radio enthusiasts. This high-quality capacitor, specifically model 167-153-11, is designed to deliver exceptional performance and reliability in your radio equipment.

The Johnson 140 pF Capacitor Transistor is a variable capacitor, which means it can be adjusted to change the capacitance value. This feature is particularly useful in crystal radios, where the capacitance value is crucial for tuning in specific radio frequencies. The capacitance value of 140 pF (picofarads) is ideal for the medium waveband, making this capacitor an excellent choice for crystal radio enthusiasts.

The transistor aspect of this component is a bonus feature. Transistors are semiconductor devices that can amplify or switch electronic signals and electrical power. In the context of this capacitor, the transistor can be used to control the capacitance value, allowing for more precise tuning.

Constructed with high-quality materials, the Johnson 167-153-11 Capacitor Transistor is built to withstand the rigors of regular use. It features a durable, robust design that ensures longevity and reliability, even in challenging radio conditions.

In summary, the Johnson 167-153-11 140 pF Capacitor Transistor is a versatile and reliable component for Ham Radio and crystal radio enthusiasts. Its adjustable capacitance value, transistor control, and robust design make it an excellent addition to any radio setup.

1. Quality components: The Johnson brand is known for producing high-quality electronic components, ensuring reliable performance and durability.

2. Easy assembly: Crystal radio kits are typically easy to assemble, making them a great option for beginners or hobbyists looking to build their first radio.

3. Educational value: Building a crystal radio kit is an excellent way to learn about basic electronics and radio technology.

4. Portability: Crystal radios are small, lightweight, and battery-operated, making them easy to carry around and use on the go.

5. Cost-effective: Crystal radio kits are generally more affordable than modern radios, making them an accessible option for people on a budget.

1. Limited range: Crystal radios have a limited range compared to modern radios, as they rely on crystal oscillators to generate frequencies.

2. Sensitivity: Crystal radios are often less sensitive than modern radios, meaning they may not pick up weak signals as well.

3. Sound quality: The sound quality of crystal radios is generally lower than modern radios, due to the lack of advanced filtering and amplification circuits.

4. Lack of modern features: Crystal radios do not have modern features like FM/AM tuning, digital displays, or built-in headphones, which some users may find limiting.

The 167-153-11 Johnson 140pf capacitor transistor ham crystal radio kit is a great option for beginners or hobbyists looking to learn about basic electronics and radio technology while building a functional radio. Its high-quality components, easy assembly, and educational value make it an attractive option. However, its limited range, sensitivity, and sound quality may be a concern for users looking for more advanced features. Ultimately, the decision to buy this kit depends on your specific needs and interests.

If you are a beginner or hobbyist looking to learn about basic electronics and radio technology, or if you are interested in building a functional radio with high-quality components, the 167-153-11 Johnson 140pf capacitor transistor ham crystal radio kit is a recommended option. However, if you are looking for a radio with advanced features and a wider range, you may want to consider other options.

Details:

It features heavy duty construction with ceramic insulation. Capacity decreases with clockwise rotation, 180 degrees total. I think a couplet could be used to extend the shaft, but do not have one available try. Note there is a tiny chip out of the top near part number.

Up for sale is an e. There is 6-32 hardware for mounting to a chassis.

The shaft is slotted and inch long it accommodates a standard knob. I measured the capacity with my china Cr meter to be approximately pf.

Size is approximately w x l. Johnson air variable capacitor part.
