Here is a simple, but not exact description. Assume that the
frequency range of the audio that is transmitted is from 1000 hz
to 4000 hz. The frequency inverter converts the 1000 hz signals
to 4000 hz and the 4000 hz signals to 1000 hz. The 2000 hz signal
is converted to 3000 hz etc.

To decode it, you just run it through the inverter once more.

Well, I finally took the plunge and got me a Fairmate HP2000.  It's
virtually the same as the AOR AR2000 - I wonder if I'll regret not
going for the AR1500, which offers SSB?  How's 'normal' shortwave
reception with these critturs?

Main problem so far is the appalling manual.  I can't get the
instructions to work for transferring a frequency found during a
search directly into a memory bank.  Can anyone out there help?
Please don't say 'RTFM'!  I have.

Instructions given are:

(Whilst searching, having locked on to an interesting signal)

A.  Press HOLD
B.  Press ENTER
C.  Key in a bank number (your choice)
D.  Key in a channel number (your choice)

-- at this point it will only accept one digit (the machine has
   channels 00 thru 99 in each of memory banks 0 thru 9) and then
   displays a bank number of 0.  Next key press restarts the search.
   So this is as far as I get, though the next step is --

E.  Press ENTER

Can anyone help?  I guess it's boring for most of the old hands here,
so email would be fine.  Thanks in advance.  It's a drag having to key
in each frequency individually.

I'm sort of doing something like this as a learning experiment, really.
What I'm doing is writing some software for a Sun workstation to decode
the digital data found on the pager frequencies.

Its probably applicable to cordless phones as well. I have no plans
for anything realtime, though.  What I do now is tape the digital data
stream and sample that into the workstation, and work on the sampled
data stream.

     Depends on the frequency, and type of antenna you have.  The higher 
in frequency you go the shorter the range the transmission has (generally, 
not always).  A high mounted, broadband, outdoor antenna will do much 
better than an indoor one.

Does anyone know of any digital signals that can be received on a
scanner and sent to a computer. I have a Pro 2004 scanner.

For instance there is a fairly new service operating at 931 MHZ
which allows people with a Newstream receiver to use radio
frequencies to send data messages to computers. It is like an E-mail
system that uses the airwaves. The receiver looks like a big pager
that stores messages sent via commercial or private E-mail systems
for later downloading to a laptop or Dos based pc. It can store up
to 15 pages of material, maximum length of individual messages is
1500 characters. Messages can consist of text or binary files and are
downloaded via the serial port on the computer. Bye for now.

Subject: Re: What's CTCSS?
Date: 16 Nov 92 22:15:36 PST
Organization: BBS

CTCSS is a subaudible tone used by many radio systems as a sort of safeguard
for the systems (also known as PL or "private line" in certain circles).  these
tones are transmitted from the time the radio microphone is keyed to the point
of unkey of the microphone.  these tones are mostly inbetween the 67.0Hz to
250.3Hz range, and on most radios are undetectable or unnoticeable because the
radios aren't designed to reproduce audio at those low frequencies.  they
filter them out and use them for CTCSS information.  

The tones can be thought of as different "keys" to unlock different doors. 
let's say you have two businesses that share a frequency.  since the businesses
don't want to hear each other's radio traffic, and only their own, they use
CTCSS as a code key for private operation.  one business operates on 151.625MHz
with 103.5Hz as their CTCSS tone.  The other business operates on the same
frequency, but their tone is 162.2Hz.  While your scanner picks up both of
these businesses, and it may sound sometimes like they are talking over each
other, they are completely unaware of each other's conversations because each
of their radios listens for the proper CTCSS tones.  I have the same scanner as
you, and I added the CTCSS board because we have multiple users in the bay area
(San francisco, san jose...) that share radio channels.  
Other reasons for the use of CTCSS tones are to activate repeaters and certain
links and the like.  Most commercial repeater systems (police, fire, medical,
municipal) won't activate or be keyed by someone who can transmit on their
input frequency, unless that person is also transmitting the proper CTCSS tone
on their radio.  

Having a CTCSS board can greatly reduce the interference you receive in most
cases from bleed over from a nearby channel etc.,.  There are several 300 watt
paging transmitters in san jose that bleed over most of the police and fire
channels i monitor, but they are almost completely blanked out when the CTCSS
board is used.  The unit can save you headaches, yet give you headaches if you
install it and don't know the tones for the frequencies in use in your area. 
it's about $50 and just plugs in.

I heard one today that got me thinking a bit (but I didn't act on it).
Lady and fellow are talking and fellow tells lady that when **** gets
to the house (expecting company?), she should dial xxx-xxxx (his pager
number) and enter 4646.  I recognized the number as a local pager
company (my own is on the same exchange), and thought "what would
happen if *I* were to page him at some random time with this number :-)."

A good chuckle over what might happen was all I got.  Mostly I thought,
why bother.  All it would do would be to confuse some folks...

>1. Exactly what frequencies are used for cellular calls
There are two licenses granted by the FCC in any given service area. (I assume
you are talking about the North American Cellular System.)  
The spectrum allocated in total is from 824.040 MHz to 893.970 MHz.  The equation
for channel # to frequency mapping is:
	Mobile:		1 < Channel < 799	.03 Channel + 825.000
		      990 < Channel < 1023	.03 (Channel - 1023) + 825.000
	Land:		1 < Channel < 799	.03 Channel + 870.000
		      990 < Channel < 1023	.03 (Channel - 1023) + 870.000
>2. What frequencies are used as control channels?
Control channels are from 313 to 333 on the A system, 334 to 354 on the B system.
In addition, there are upper control channels that I can never remember, but are
in the middle 700s.
>3. How does a cell site signal a cellular phone to ring?
The cell system sends a message on the Forward Control Channel on all setup channels
and at all cell sites which is decoded by *all* cellular phones tuned into that
system.  Encoded in the message are the ESN (Serial number) of the phone and the
MIN (Phone number).  When a phone recognizes its MIN and ESN, it responds on the
cell site it has been monitoring.  The cell site then sends acknowledges the page
response at which time the mobile unit is allowed to page.  When the phone is 
answered, the mobile sends a message saying the page has been responded to. At that
point, the cell site sends a message telling the mobile which frequency to tune to
for a voice channel.  
>4. How does a cellular phone tell the cell site that it wants to make a call?
Essentially the same as responding to a page, but the mobile initiates by sending
a message requesting access to the system along with the phone number it wants to
call.  If there is an available channel, the cell site responds with the channel
the mobile is supposed to tune to.
>5. How does the cell site tell the cellular phone to switch frequencies 
>   when the call is being handed off to another cell site?
The audio is blanked for a very short time during which the Forward Voice channel
message is sent telling the phone what channel to tune to.  The mobile unit then
responds.  After tuning to the new frequency, the audio is unmuted.
>6. What kinds of status and control messages are exchanged between cellular
>   phones and cell sites and how are they encoded?
That is much too broad a question to answer here.  You should pick up a book on the
subject or a copy of IS-54.
