The meter, then, shows the strength of RF energy at the tuned frequency. Some meters even have a headphone jack so you can listen to the signal (making it almost a crystal radio). One reason many ...

Carrier Wave Generator The Wave Generator creates a high-frequency radio signal. The frequency of this signal is many times greater than the frequency of the audio wave. This signal will "carry ...

Astronomers have uncovered something pretty remarkable emerging from the depths of space, after detecting a powerful series ...

Many Digital radios have a signal strength display which enables you to position the Radio for the best reception (usually a number of blocks) as a guide of reception quality. Unfortunately ...

He designed a transmitter to send and a receiver to detect radio waves. By the end of the century Marconi had managed to send signals over several miles with no wires, and the idea was taking hold ...

It’s a phenomenon called multi-path propagation, and it can render the radio signal useless and unintelligible. To overcome these factors, mount your antenna as high as possible. The higher the ...

On a balmy August evening in 1977, an enormous radio ... a signal coming from a long way off would increase for 36 seconds before decreasing and tailing off again. The “6EQUJ5” signal strength ...

We locked on to popular FM and AM radio stations with ease, and the green LED light was especially helpful to confirm when we had the strongest signal. An optional external FM antenna is also ...

Before the simulated alien signal could be decoded, it first had to be extracted from the raw radio signal data. That took just 10 days, thanks to a group of some 5,000 citizen scientists.

If a HD Radio signal becomes too weak, the radio will automatically switch over to the parallel analog signal. In our tests, HD Radio can live up to its promise of improved sound. The HD Radio ...

The BBC do not own the Radio Teleswitching System (RTS), we simply deliver the signal using our transmitter ... being replaced as part of the smart meter rollout programme. To enable the ...

The Republican strategist said he was paying close attention to Dearborn, in the battleground state of Michigan.
