how to program MCS2000 to Ham-band ?

MCS2000 CPS Hex .exe file

I am using CPS Ver R02.03.00, i have a MCS2000 110 watt VHF ," K " split M01KLN9PW6AN

I have been reading how to hex edit the .exe file in the CPS to program the radio from 146Mhz down to 136Mhz.     

I haven't done hex editing for 15 years and having a difficult time trying to do it.   Can someone point me in the right direction where i can find an easy explanation on how to do it.

Is there any way to program MCS2000 that operate between 450-512MHZ to the ham bands ?

If you are using CPS, you would edit the mcs2000.exe file found in the CPS folder. Make a backup first so that you can go back to the original file if you make a mistake.

The CPS hack should do a search in the .exe for the lower freq limit using intell signed you should find it. I currently dont have the time to look (maybe next week I will if you are willing to wait)

How did you modify the file? I have been looking for two days and can't find a solid answer. I want to get my VHF radio to go down to the lower end of the ham band. 

You use Hex Workshop to edit the band limit for RX. Note that Hex Workshop contains a base convertor that you can use to help determine the hex value corresponding to a particular frequency, in which case you would select "byte order" for the hex value as "Intel" and the "data type" as "long" or "unsigned long". Either of the following changes should work:

RX Lower Limit:450.0000 = 8074D21A

Change to:
430.0000 = 8047A119
420.0000 = 00B10819

by far the easiest way to edit those values is to use the search and replace feature in Hex Workshop. Doing so will avoid typing errors.

I used the search and replace and it changed all 6 now what do i have to do just save it

I looked up the values for you change 00321B08 to 80A4BF07.   Feel free to post the addresses changed so others dont have to redo the work.

he opened the.exe in a hex editor (Hex Workshop) and changed the lower limit from 450 to 440. You will have to do the same exept change the 146 to 144.

I opened the .exe file in Hex Workshop.I located 80C8B308 and changed it to 80A4BF07.    I don't have a radio to read yet so i download a C/P from the Super Codeplug site to try.
The C/P is from a M01KLN9PW6AN VHF 110 watt 146-174Mhz.
After changing the .exe file the C/P now will do 130-174Mhz, i'm just wondering if that sounds right.
Not that i will be programming anything below 136Mhz.

dont look for 144 look for 80C8B308 this is 146 mhz. 80C8B308

Yes you use hex workshop. you need to look for 8074D21A and change it to 8047A119. feel free to post the edit locations if you want.

open up the .exe then use the find (edit>find) to look for your values. Also dont forget to set your main window to 0-F so you read correct addresses.

i think i'm getting close! I used the "find" and entered "8074D21A" and it found 6 places and displayed them in bottom right corner window, but when i click on the add in that window it highlights them in yellow up in the main screen but the add are not the same as someone posted above. Is this normal, here is what it shows

0099EBC4
0099EBE0
0099EC0C
0099EC28
0099ECE4
0099ED00

Now can i just change the yellow highlighted areas to the new values which will be "8047A119" and save.
Also what did you mean buy set main window to 0-F i don't understand

by far the easiest way to edit those values is to use the search and replace feature in Hex Workshop. Doing so will avoid typing errors.

I used the search and replace and it changed all 6 now what do i have to do just save it

yes, you just need to save the modified file and put it in the folder where it is installed on your computer. Make a backup of the original file first (e.g., mcs2000_original.exe), save the modified file with a name like mcs2000_OOB_modified.exe, and save the modified file as mcs2000.exe in your installation folder. Once that is done, run CPS and program your radio. CPS will accept the OOB frequencies, and if your radio will go down that far, it will work. Otherwise you will get a VCO lock error.

I have modified the MCS2000.exe file in a HEX editor and all works fine

Ok quick question here. I'm not new to the big M, use to use spectras and still have my MTX9000 and MT2000. Now with the MCS2000 series, how far down can you go before you lock the vco. I imagine the 146-174 can go down to 144 no problem but can the 450-512 actually go down to 420?
