    Default Help decoding paging tones?

    I am sorry for the elementary question. I have searched and can't find the answer.

    If I have paging tones being given to me in this format

    06da
    06dc

    How to I convert this to standard frequencies for paging tones? Does someone have a chart, and what format are these in?

    Thanks, rob

    Rob,

    Can you be a little more specific on what you are trying to do and what you are working with --

    Thank you... could I ask you to share exactly how you decoded that? Thanks, rob

    It only runs on 16/32 bit machines. It will not work on x64 machines. Run it in dosbox.

    Thank you. I will give it a shot. I was also hoping that there was some printed material on this as well. Maybe not.

    Thanks, Rob

    That's why I asked what you are working with.

    The appendixes of the Bosch / Telex Csoft manual have a lot of data on this subject.

    I'm sorry Phonebuff, it didn't see your post for some reason on my phone.

    I had requested from a customer their paging tone information, to which they gave me the above listed format (which I thought was CCII format) I searched high and low for any type of printed decoding document. Pezking has a interactive decoder, however it has issues running on newer machines. I was trying to figure out dosbox, which is just one additional headache today.. grr.

    Does the bosch/telex manual have a decoder list?

    Thanks, Rob

    LOL, I do... I have a little mini stockpile of them. For the life of me, I have never, ever been able to get the USB program cable to work for HT/CDM. I have only one customer still hanging on to the Quantar, so I keep lugging my windows XP toughbook around for the quantar and HT/CDM stuff. Once we have kicked all that crap to the curb it will be a breath of fresh air for me.

    I really wish I could get the HT/CDM cable working on W7. I have one lenovo with XP that it works fine. I hate having to tote around the two machines everywhere.

    On an upbeat note, when I got home waiting for me last night was a new to me (demo unit) fully loaded freedom R8000C that I bought. I cant wait to start using it.

    The Centracom Gold Elite Manual has a lot of helpful info on decoding the paging tones. When I go to work tomorrow I will pull the manual out and scan in the pages. PM me your email.

    Here is also an excellent guide by medians with useful information in it as well.

    Why not just post them here? We aren't radioreference, you can share with the group.

    Thank you guys for all the help and documents.

    Either I am just not getting it or I am full blown mouth breather. So, I look at the manual that SteveC7010 and others have attached. I still cant figure out how to decode my original tone sets of 06da
    06dc.

    Now, pezking got me the correct answer, which I am super grateful for. I would really like to fully understand how to arrive at the answer with the attached documents, which should cover what I need?

    Sorry in advance, grrrr.

    If you look on page 2-4 of the documentation, "Procedure for Converting Keypad Code to tone frequency" is what you want to look at.

    Step 1:

    Write Keypad Code Down: 06dc

    Step 2:

    Convert prefix (the first two digits) to the column data using table 2-5 (and use the second part of the table, Prefix to Paging Group):

    06 = 46

    Step 3:

    Append the converted prefix to the suffix (last two digits)

    46dc

    Step 4:

    Decode. The first digit indicates first Tone's group. Second digit indicates second Tone's group. Third digit is first Tone's row. Fourth digit is second Tone's row.

    4d 6c

    Now use table 2-4......

    Group 4 Row D - 701.0
    Group 6 Row C - 1130.0

    Does that help?

    Yes, this is what happens when you try to do this on a blackberry while driving, lol. I got it, and was missing looking at the wrong chart. Thank you very much!!

    Motorola certainly made it a convoluted process to encode and decode....

    I had an issue with a MCC7500 and K2 core setup that required me to encode a tone pair into the cap code. No documentation with the new stuff covered this, hoed out the massive Centracom manual and we were good to go. Funny how the old stuff can still be a help.....

    Like many things with CentraCom, the classes at Moto explain a lot that is not covered in the manuals. My best cheat book was the notes I took when in Schaumburg.

    I used the same DOS tool pezking posted to convert audio frequencies to capcodes going from Zetron to MCC7500. When your tone tables are linear, it makes conversion much easier.

    I always feel bad for the comm managers that maintain systems including regional fire comm centers or multiple rural vollie FDs... those tone tables are anything BUT linear.
