CPS R02.02.00 Modification for MCS 2000 900MHz

[d119]

OK. I figured out what to change in R02.02.00 CPS for the MCS 2000 to operate in the 900MHz amateur band.

This modification should allow receive down to 927.0000MHz, and transmit up to 903.9875MHz.

In the MCS2000.exe file, use your favorite hex editor (I prefer Hex Workshop) to search for the following hex values:

AC3CC335 (represents 901987500)

Replace it with

2CC1E135 (represents 903987500)

Then

9428BB37 (represents 935.012500)

Replace it with

C0E54037 (represents 927.000000)

Please make sure you search the ENTIRE document for the original values, as they may appear more than once. If I recall correctly, one value appeared twice, the other only once. Just save the file (make sure to save a backup copy!) and then launch the CPS. Read your radio, and you should now be able to enter receive frequencies from 927.0000 through the commercial frequencies, and transmit frequencies up to 903.9875.

Enjoy.

This did the trick now I can switch to using CPS instead of RSS. Now it will be much simpler to program my MCS2000. Now on to my MTS2000.

The procedure should be the same for the MTS 2000. I'm glad this helped someone!

Are there multiple places that must get patched for each model radio that's covered by the program, or does one change do every model? I realize that the older programs usually only covered one model line, so this wasn't an issue.

It was SOOOOOOOOO nice of Motorola to make the limits an exact 12.5 kHz channel frequency. Sure made it hard to find references to 896, 902, 935, and 941.

Thanks for the info.

With Hex workshop or any decent hex editor, just do a search and replace of all instances as originally described. I actually opened mine up a bit wider by a couple of megs, just in case.

This fix also worked on CPS ver 12.00.00 for the XTL-1500 Mobil.
Thanks, TR
