Why a phone scrambler? The Threat…
If someone is actively targeting you, attempting to gather information information for whatever purpose, it is almost guaranteed that your cordless and cellulat telephone conversations are being listened to using some types of ‘ spy equipment ‘.
And it is likely that there will be an effort to tap your hard-wired telephone as well - (more on that in a bit).
If you are using a digital cordless phone with spread spectrum technology, you can be faily confident that the signal between the handset and the base isn’t being monitored.
However…
Once your cordless phone sends a signal from the base down the telephone line, you no longer have a digital spread spectrum signal.
The Solution
With this in mind, you may wish to install a phone scrambler on your line to secure your sensitive cordless and regular phone conversations. Doing so will prevent even Big Brother from making sense of your telephone calls.
Once available only to the military and government agencies, the very best units (such as the STU-III), costing just a few thousand dollars each, are available to the commercial market.
Phone scramblers may be divided into the following broad categories:
Frequency Inversion
The simplest form of scrambling - it inverts the high and low points in the signal.
If you are simply trying to keep someone from listening in on your conversation on an extension, this type of units will work but anyone who puts any effort into defeating the frequency inversion will have little trouble doing so.
Rolling Code
This one takes frequency inversion and add an additional function so that the pivot point around which the frequency is scrambled is continuously changing.
This makes decoding of the signal much more difficult. By using a rolling-code phone scrambler you will secure your conversion against any casual listeners, criminal eavesdroppers, and local investigators and law enforcement agencies.
These units are in about the same price range as the basic frequency-inversion ones.
Digital Encryption
Digital scramblers are the most secure and the most expensive. These units are used by the military and government agencies - and they start selling for 1500$ +.
If you are concerned about having your phone calls intercepted by government agencies or are afraid of industrial espionage, digital encryption is the answer.
But for most of us the sensitivity of our conversations does not require this level of security and the associated expense.
Please Remember
It is important to remember that you must have a phone scrambler on each end of the conversation - and that scrambling your voice on the telephone line does not defeat an electronic listening device that is placed to intercept room audio.
