|

|
|
|

|
|
|
|||
|
|
The above is a list of the two channel cordless phone frequencies.
|
|||
|
|
They are a paired network, however if you have a cordless phone that
|
|||
|
|
does work on the paired basis, for example 46.93 & 49.99, by monitor
|
|||
|
|
ing just the 46.93 frequency will provide both sides of the conver
|
|||
|
|
sation.. Monitoring the other end 49.99 would be just the person using
|
|||
|
|
the cordless phone.
|
|||
|
|
This only works on cordless phones using the 46 mhz paired scheme.
|
|||
|
|
|
|||
|
|
The older cordless phones worked mainly on the 49 mhz. band, these
|
|||
|
|
versions only radiate the person using the cordless phone, to monitor
|
|||
|
|
the other side of the conversation you have to have a Short Wave Radio
|
|||
|
|
and slowly tune between 1.5 & 1.9 Mhz. You will notice at trying to tune
|
|||
|
|
in with the SW that you get alot of static, this is one of the main
|
|||
|
|
reasons that they switched to the 46/49 paired scheme, to get a clearer
|
|||
|
|
reception on cordless phones. That is for the owner of the Cordless
|
|||
|
|
Phone, not a monitor... (grin)
|
|||
|
|
|
|||
|
|
Baby Coms or Room monitors are used mainly to monitor a babies room, to
|
|||
|
|
see if the baby needs something. However uses for these little gadgets
|
|||
|
|
could be anything for instance surveillance..
|
|||
|
|
|
|||
|
|
Baby Coms also use the 49 Mhz spectrum, most notibally on:
|
|||
|
|
|
|||
|
|
49.830 49.845 49.860 49.875 49.890
|
|||
|
|
|
|||
|
|
Baby Coms are quiet sensitive, quiet sensitive, usually meaning that
|
|||
|
|
other areas of a house that has one are transmitting into the Mic..
|
|||
|
|
Get my drift?? It is sometimes very funny.. Cruise around and give a
|
|||
|
|
listen....
|
|||
|
|
|
|||
|
|
|
|||
|
|
Another device that uses the 49 Mhz band is the line of personal
|
|||
|
|
communicators, the best known is Maxon. These little radios are
|
|||
|
|
very valuable to have. They are very inexpensive and a ordinary
|
|||
|
|
store model will have a range of up to 1/4 of a mile..
|
|||
|
|
They work on the same band settings as do Baby Coms 49.83 - 49.89
|
|||
|
|
|
|||
|
|
My Maxon communicators are always charged and ready to go, for ex
|
|||
|
|
ample, long ago when my Satellite Dish would go out of line due to
|
|||
|
|
a storm or something, I'd have to run out there and at each little
|
|||
|
|
adjustment stop and yell into the house, now-a-days we slap a couple
|
|||
|
|
Maxons on and the dish is set in minutes..
|
|||
|
|
|
|||
|
|
One nifty model that Maxon came out with is there Ear-Mic models which
|
|||
|
|
the microphone and the earphone are one piece that fits in your ear,
|
|||
|
|
the same way as a normal earphone does. As you speak your vocal cords
|
|||
|
|
vibrate this vibration is actually what you are speaking, anyway it
|
|||
|
|
reverberates inside your head and the ear mic picks these sounds up.
|
|||
|
|
Really it works, this method has been in use for many years, notice
|
|||
|
|
that you only see an earphone in Agents ears, there using this type
|
|||
|
|
of system... Anyway all you have to do is whisper and the person with
|
|||
|
|
the other communicator will hear you..
|
|||
|
|
|
|||
|
|
Want to have some fun??? Well as you can see the Maxon Communicators
|
|||
|
|
use the exact same frequencies that Baby Coms do.... Hmmm.... do you
|
|||
|
|
have a friend with a Baby Com? Well late at night drive near his house
|
|||
|
|
and turn your Maxon on and make some weird noises or whatever you want
|
|||
|
|
to do.. Note make sure you know his babycom frequency, so you can set
|
|||
|
|
your Maxon to it...
|
|||
|
|
|
|||
|
|
Communicators like the Maxons can be bought anywhere nowdays, for inst
|
|||
|
|
ance, Radio Shack has them under there name, but Maxon sales to them..
|
|||
|
|
You can buy several types, handhelds, headset models and even base
|
|||
|
|
models. Dont even get one that has only one or two channels, get the
|
|||
|
|
versions that cover all five...
|
|||
|
|
|
|||
|
|
Maxon Communicators exact frequencies are:
|
|||
|
|
|
|||
|
|
A - 49.83 B - 49.845 C - 49.86 D - 49.875 E - 49.89
|
|||
|
|
|
|||
|
|
There is not much that you can do internally to soup up the juice on
|
|||
|
|
these babies, I did see a circuit for making a preamp and will make
|
|||
|
|
a file on that in the future. Things you can do are this. On the
|
|||
|
|
Handhelds what I do is take out the factory antenna and I mount a
|
|||
|
|
BNC Jack onto the frame you can then use a wide variety of antennas
|
|||
|
|
on the market, I have one on the car and one up in the tangle of anten
|
|||
|
|
nas in my trees.. I also use a whip for walking with the handheld.
|
|||
|
|
As for the Base, definately add a Bnc jack and an outdoor base...
|
|||
|
|
|
|||
|
|
I think you get the general idea here, be on the look for files
|
|||
|
|
I will be putting out on tips to use your baby coms and communicators
|
|||
|
|
for all sorts of different reasons.. One being surveillance... Hidden
|
|||
|
|
Mics, body Mics,, etc.
