A:  Yes, this is our house and works great

A:  The unit is easily able to be programmed however does not come programmed.

A:  No, it is not programmable as it is already pre-programmed.

A:  Yes. Because the other way to do it would not fit on your entire desk or table. It would be what is called an analog scanner. This unit, like any others before the 1970's uses electronic circuits to detect certain frequencies. Those frequencies are grouped into bands by the FCC and other radio related groups. You would have to be really really old to have a scanner that uses analog radio circuits. A radio signal is a continuous electronic emission. Think of it as a wave in an ocean. The closer the waves are together, the greater the FREQUENCY. Now think of a billion of those waves. To detect, reduce to human hearing range, amplify so it can be heard etc. Is simplified. These type units SAMPLE frequencies to search for bands. Like picking the middle 100, or 1000, or 1,000,000 waves out of your ocean. This is much easier since the transmissions are not one long continuous signal. They are transmitted as digital data - meaning there is a code of "on" and "off" signals carried over a carrier frequency - like an FM radio station. The FM abbreviates Frequency Modulation. With modern technology, these changes in frequency are far far easier than back in prehistoric '50's and before. All due to the existence of the transistor which can switch outputs faster than the old vacuum tubes could ever possibly do. That is why they are called digital scanners. (More than you wanted to know I bet, but that's it in a nutshell.) For further reference consider: http://electronics.howstuffworks.com/radio-scanner.htm
