MTS2000 CPS 2.00.03 900 MHz band edges

Post by DarkHelmet »

In case this helps anyone else. This is for the 2.00.03, which is the newest CPS for the MTS2000

Hex edit the mts2000.exe (make a backup first!)

RX Lower Limit / TX TA Lower Limit:
Default Value: 935.0125 = 9428BB37
Found two places in the file: 0x906BB4 and 0x906C8C
Change it to 926.0000 = 80A33137


TX RPT Upper Limit:
Default Value: 901.9875 = AC3CC335
Found one place in the file: 0x906B20

Change to 904.0000 = 00F2E135

The newer versions of MTS/MCS CPS (e.g., R02.02.00 and R02.03.00) are modified in the same manner.

Open MTS2000.exe or MCS2000.exe using your favorite hex editor. Use the replace command to look for the following hex strings, and then replace them with the provided strings. Make sure you are searching for hex values.

RX Lower Limit / TX TA Lower Limit
935.0125 = 9428BB37
Change to
926.0000 = 80A33137 or 927.0000 = C0E54037
The replace command should report changes in two places

TX RPT Upper Limit
901.9875 = AC3CC335
Change to
903.0000 = C0AFD235 or 903.9875 = 2CC1E135
The replace command should report changes in one place

Save your work (making a backup copy when prompted is recommended), then close Hex Workshop. Open your CPS software and confirm that you can now enter frequencies within the ham band without the software flagging them as invalid. If you can, then you’re all set! If not, delete your existing MTS2000.exe or MCS2000.exe, then rename the extension of your MTS2000.bak or MCS2000.bak file that you created to .exe, then try again.

Note: Even though you can program the ham bands, you may find that your VCO will not lock on those frequencies. It can be hit or miss.

Number 6,
Edited my R02.02.00 .exe file as you show. The RX edits worked, but the editor could not find the TX RPT upper limit (AC3CC335) string? could this string be incorrect? I'm trying to reprogram a 900 MHZ MTS2000 radio I was given. So far it's no joy, Hi, Hi. Any help is appreciated.
