Benefits Of Scanner V. Airband Radio

Thu Jan 06, 2005 1:17 am

Hi,

I have a digital airband radio (ie I can dial the exact frequency of my local tower 122.6). I have been contemplating buying a scanner for a long time but don't really know the benefits that it would bring compared to what I have now?

Any help on Radio V. Scanner would be appreciated.

Hello Scotland,

You have no digital radio, you have a (radio) receiver with a numeric display and the capability to enter directly frequencies from a keypad.

A scanner is exactly the same thing, it is simply called scanner because it has a function that allows to automatically search for busy frequencies.

The scanning function can be performed either
-from the low to the high end of that particular radio frequency range
-the freq. range between two slef-chosen preset frequencies
-only pre-programmed frequencies you have yourself chosen as "memory
channels"

It might also have a "dual watch" function, whereby it actually scans rapidly two frequencies and locks once it found a signal.

I have a scanner and it works pretty well. I can get BOS, PVD, MHT, and LEB nicely.

Would I be right in assuming that, if for example 5 different frequencies were available where I am, the scanner would automatically tune in to which ever frequency is busy?

Most (all?) scanners allow you to choose however many freqs you want, and the scanner will scan only them-- or, it can start at the end of the freq range and scan every freq, if you're searching for freqs you don't yet know about.

Welcome to A.net by the way, and please note that this kind of subject would preferably be posted in the "aviation hobby" forum.

If you have a radio with scanning function and a memory bank (to store frequencies of your choice into memory), you can indeed store your 5 (or whatever the radio allows) favourite frequencies in memory, and then let the scan function operate.
As soon as it will find a signal on one of the said 5, it will stay on that one (until you restart the scan).

Also a scanner may have a wider radio band range. For example you may be able to listen to police and fire communications.

The scanning method that I prefer is to have all the frequencies of a particular airport programmed into a memory bank. The scanner checks all the frequencies programmed in rapid succession and stops when there is activity on a channel. Of course, there can be communications on several frequencies at the same time but you can only tune into one at a time. To deal with this, I put my favorite channel (usually tower frequency) in as the priority channel. The scanner then will jump back to the priority channel even if it is stopped on a different one. The priority function is found on most uniden scanners.

It all depends on what you want to do. If you are at a busy airport and have a scanner, it really does not scan as every frequency is usually busy. On the other hand in a house or a less busy airport a scanner is nice as it picks up traffic all various tower, approach, center frequencies, etc.

Checko,

A scanner is nothing else than a plain and simple radio, it only refers to a function of the radio, which by the way almost all wideband (= more than one specific frequency band) radios do have since the advent of the synthesizer technology and numeric displays.
