Not really. For years they have been using K band and Ka band. Yet fairly recently they have mostly phased out the use of K band. New Zealand is allowed to use the same three Ka band frequencies which are used in the USA. These Ka frequencies are 33.8, 34.7 and 35.5. The 34.7 Ka frequency is the easiest to detect with any quality radar detector. The 35.5 frequency is poorly detected by some radar detector brands, notably Cobra. The 33.8 Ka frequency may be only fairly well detected by dome radar detector brands.

Why RC coupled amplifier is called audio amplifier?

Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.


The frequencies 88.1 - 91.9 FM are?

Generally FM radio range is from 88 MHz to 108 MHz. Frequencies are issued to commercial broadcasters by a government authority. Broadcasters need a licence to use a frequency. This description may change depending on the country.


How did the titanic disaster change sea travel?

More efforts were put in to avoid collisions such as detectors like sonars and radars, more lifeboats, and even emergency escape plans


What is a change control program used for?

Change control or source control software is to keep track of all the modifications made to source code or documentation during development.With change control in place, you can easily check which changes were made recently (and by who), and roll back to an earlier version if somebody makes a change that breaks the program you are developing.Popular open source change control programs include CVS and Subversion, there are also a number of commercial alternatives available.


What are loop detectors are use to do?

A smoke detector detects smoke, a fire detector detects fire. A loop detector, surely, detects a loop. Many detectors are also based on a loop of wire. For example, loops within the tarmac detect the presence of a car (a mass of ferromagnetic material) and triggers or promotes a change if the lights from red to green. Other sensors use loops as aerials, for example in theft-prevention systems used in shops. In the context with computer programming, one can envision a variety of methods to detect a loop which fails to terminate (and unintentionally endless loop, or one which doesn't terminate in a timely fashion). Critical loops can be monitored for a maximum number of iterations or a maximum duration.

How do you change the pitch sound?

Adjust the wavelenght! The higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Basically, the longer the wavelength, the lower the pitch.
