IDFREQS version 1.3
IDFREQS (IDentify FREQuencieS) is a program written for scanner owners
that allows them to print out a list of all frequencies stored in their
scanner, along with text descriptions of agencies that use them. Since
some scanners will actually "round" a frequency when entered, and since
you can actually hear frequencies that are just a few khz off of center,
IDFREQS considers frequencies that are within 3khz of each other as the
same.
IDFREQS first loads a file that you create containing channel numbers,
along with the corresponding frequencies, currently in your scanner.
Next, master frequency data base file(s), that contain frequencies along
with text describing them, are searched to find descriptions of who uses
those frequencies. If there is enough memory to do so, descriptions for
each frequency are sorted alphabetically. The results of the search are
written to another file that you specify.
The command line for IDFREQS looks like this:
IDFREQS <FILE1> <FILE2a>..<FILE2n> <FILE3>
Examples of actual command lines are:
IDFREQS scanner.txt mstrfreq results.txt
or
IDFREQS scanner.txt mstrfreq.1 mstrfreq.2 results.txt
-------------------------------------------------------------------------
FILE1 FORMAT
FILE1 is a file you must create yourself which contains the data stored
in your scanner. This is always the first file listed on the command
line. Each line contains both the channel number and the frequency
stored in it, terminated by a carraige return/line feed:
ccc ffff.ffff<cr>
ccc is the channel number, up to 4 digits (0001, etc). You don't have
to list channels that are not used, but you do have to list the channel
numbers in ascending order, otherwise the output will not be in order.
Note that leading zeros are not necessary, but leading zeros will be put
in when the results are generated. For example, both 007 or 7 are OK.
ffff.ffff is the frequency, up to 9 digits (including decimal point) total.
No more than 4 digits before, and no more than 4 digits after, the decimal
point. Values in this field do NOT have to be in ascending order, and
duplicates are OK. If you list a frequency of 0, a "** BLANK CHANNEL **"
description will be listed for that channel. Note that you don't have to
list all of the digits, just significant ones. For example, both 0045.3000
or 45.3 are OK.
FILE1 should ideally look like:
0001 042.3250<carriage return/line feed>
0008 162.6650<carriage return/line feed>
0400 345.3225<carriage return/line feed>
Every character in this file, other than the decimal point, MUST BE A DIGIT!
The delimiter between fields can be space(s) or tab(s).
If you don't follow the format for this file, IDFREQS will fuss and abort!
-------------------------------------------------------------------------
FILE2a..FILE2n FORMAT
FILE2a through FILE2n is/are the master frequency data base(s) to be
searched. As you see from the command line description above, you can
specify one, or multiple, master frequency data bases. In other words,
any files listed between FILE1 and FILE3 are considered to be master
frequency databases that you want searched. Each line contains a
frequency and a text description of that frequency, terminated by a
carriage return/line feed:
ffff.ffff ttt...<cr>
ffff.ffff is the frequency, up to 9 digits (including decimal point) total.
No more than 4 digits before, and no more than 4 digits after, the decimal
point. Values in this field do NOT have to be in ascending order, and dup-
licates are OK. Every character in this field, other than the decimal point,
MUST BE A DIGIT! Note that you don't have to list all of the digits, just
significant ones. For example, both 0045.3000 or 45.3 are OK.
ttt... is a text description of the frequency and may be up to 100 charac-
ters long. Anything longer will be truncated.
The delimiter between the frequency and text description fields can be
space(s) or tab(s). If any line(s) don't follow the format for this file,
IDFREQS will skip that line and go on to the next.
FILE2a..FILE2n should ideally look like:
042.3250 Atlanta Police Dept. Dispatch<carriage return/line feed>
162.6650 Marietta Fire Dept. Fireground Comms<carriage return/line feed>
345.3225 Fred's Wrecker Service<carriage return/line feed>
-------------------------------------------------------------------------
FILE3 is the file that IDFREQS creates, and lists the channel number,
frequency, and descriptions for the frequency (if a description was found).
No, the output is not fancy, but you can edit it and do whatever your
little heart pleases to it before you print it out.
This is shareware, so go ahead and distribute it to whomever or whereever
you like.
