If you look at the information in the saved codeplug file, the first thing you will see is the serial number of the radio.( Run the hex editor and load the file with the radios codeplug data.This is intended to be used by people who know how to program this type of radios, and a little knowledge of hex is required.In this file I will tell you some information I have gathered in the past years.
Motorola Cm200 Programming Software Serial Number Of TheThe Motorola Software to program the gp300 radios 2. RIB 3. the proper cables 4. Before starting, run your software, read the radio and save the file to disk. Make backups of the software as well as the file you just saved to disk. This file I will be referring to as the Radios codeplug data file. First I need to tell you a little about how I think the software works. The Motorola software reads the radios information (codeplug data) and allows you to make changes. This information includes the radio serial number, model number, ROM version number, information about the channels (freq, signl, etc.). Free gmail hack password software downloadOnce you read a radio you could change the model number or serial number and reprogram the radio to add channels, signaling, etc. When first reading the radio, the software compares the model number of the radio to a list of models in a file called gp300.mdf (master database file), that file tells the program if the radio is vhf or uhf, the range of freq are allowed to be programmed, how many channels are allowed in the radio (2, 4, 8, 16 etc.), and how many watts of output power. Badaga dance songs free downloadIt also performs a checksum to verify that the information is okay. When saving the information to disk, the program encrypts this information so you cant change it in any way. And when reading from disk it does a checksum to make sure it wasnt tampered with. The first thing you need to do is to disable the encryption process when writing to disk. This will allow you to look at the radio information file that was written to disk and allow you to make the changes you like. Get a good hex editor. Ill tell you what to look for and you are going to have to do it yourself. All gp300 radio models start with 14 (hex) and p110s with 1C (hex) so look for occurrences of 14 74 and 1C 74 ( run the hex editor and load gp300.exe ), this is where the program decides if the information will be encrypted. In the GP300 software version I have (r05.03.00 20-AUG-93) the addresss to change are 6E8F and 6E9D. Once you find it, change the 14 and 1C to something else like ff or 00. This will allow you to write the radios codeplug data to disk without encryption. In the P110 software version I have (r08.00.00 08-FEB-96) the address to change is 7031. Note from Batwing: In version R.05.00.00 the adresses are 6D9F and 6DAD. Test run the program and try saving some files and exiting, we have found that depending on what you change the 1C74 and 1474 to, the program crashes. In R.05.00.00, try replacing the specified addresses with 1C1C and 1414, respectively. We have been told that changing the addresses to FF74 and FF74 should work as well. If you are looking for the strings to change in a different version of GP300 RSS, look for the first instance of 1474 and 1C74 after the Copyright statement near the beginning of the exe file, these will be the locations you need to change. Now you can read a radio and write the information to disk.
