Somehow [hvde] wound up with a CB radio that does AM and SSB on the 11 meter band ... and going from 27 MHz to 50 MHz seemed like quite a leap. The answer? An Arduino and a few other choice ...

[mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 chip that boosts the ...

Frequency meters measure repetitions per unit of time (frequency) and display it using a needle or graphic pointer. Industrial frequency meters are used in radio frequency (RF) and microwave ...

Description: measurements in remote locations Built-in analog output of 1mV per count SPECIFICATIONS: Measuring Range: 30 to 130 dB(A); 35 to 130 dB(C) Resolution: 0.1 dB Accuracy: ±0.7 dB after ...

CDMA 850 is CDMA technology operating in the Cellular (850 MHz) frequency band. Before the existence of GSM 850, the Cellular band was often referred to as the "800 MHz" band. "850 MHz" implies a ...

The 698-806 MHz range of TV channel frequencies (UHF 52 through 69) that were made available when the U.S. switched from analog to digital TV in June 2009 (see digital TV transition). The FCC ...

Frequencies are in kiloHertz (kHz). 1 MegaHertz (MHz) is equal to 1000 kHz. Conversion to meter bands: Meters=300000/frequency in kHz. e.g.: 17705 kHz --> 16.9 meters ...

As part of a nationwide roll-out, every home in Britain should be offered a smart meter from their energy supplier by the end of 2025. But what is a smart meter and how do they work? Here's ...

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.

The frequency illusion, also called the Baader-Meinhof phenomenon, is a cognitive bias in which someone learns a novel word or concept—and then “suddenly” encounters it everywhere ...

A frequency diagram is a type of graph used to represent a continuous set of grouped data. First, identify the largest frequency. The largest frequency is 12. Therefore, the scale on the vertical ...
