(for instance, “Y999”) to bring up the two-tone window, and then enter the frequencies
manually. (You may need to open the pager to find out the reed frequencies).
The problem with this method is that you miss some capabilities. ZbaseW lets you index
(sort), search, and print based on the Capcode field, but not on the 2-tone frequencies.
Therefore, if you use fake two-tone capcodes, you will not have the ability to search for
matching capcodes, or print out in capcode order.
Therefore, it is to your advantage to try to find out the real capcodes for your pagers. This
is especially true if you have a set of two-tone pagers, and know the frequencies but not
the code plans.
You can use the following method to backtrack to a workable code plan. Once you have
found a matching code plan, you should write each pager’s capcode on the back of the
pager.
Frequencies to Code Plan
Take one of the pagers and find its reed frequencies in the Tone Groups table. As an
example, let us say the pager has reeds inside marked 389.0 for the A reed and 953.7 for
the B reed. In the table, we find 389.0 as Tone Number 3 in Tone Group Mot 1, and 953.7
as Tone Number 5 in Tone Group Mot 3.
Now look in the Code Plans table and find the column(s) where the “A+B” shown under
the Code Plans - Groups columns matches the A+B Tone Groups you have just found
above for this pager. In this example, we found the A tone was in group 1, and the B tone
was in group 3, so we want to look for “1+3” in the table.
There are several matches to “1+3” in the Code Plans table. One is in under Mot B, 5xx
row; others are Mot F 2xx, Mot G 2xx, Mot H 2xx.
To figure out which Code Plan to use, do the above procedure again with some of the other
pagers in this set of pagers. Usually, by checking two or three more, you will find that one
of the code plan “A+B” sets is common to all of them. This is the code plan you want to
use.
If you actually have a jumble of assorted unrelated pagers from different sources, you
probably will not find a single code plan to cover all of them; in this case you can pick the
smallest number of plans needed, and use them.
Code Plan to Capcode
To figure out the capcode once you have determined the code plan: in the example above,
let us say we have chosen to use Code Plan Mot B. Looking down the “Mot B” column, at
the “1+3” row, we see that the left side of the code plan table shows “5xx”. This means the
capcode of the pager will be “B5xx”.
To find out what the “xx” part is, use the Tone Group table. The A tone is in Tone Group
Mot 1 (the “1” part of the “1+3” Code Plan). Find the first reed frequency in this column -
