GP300IVG Version 01 23rd March 1999 This Cracked version reads all currently available GP300 model numbers (As far as I know). It's good for reading radios that have been programmed with an electronic lock. All radios are recognized as 16 channel. (Note this depends on the ROM version, but as a rule a 2ch radio will not be able to get 16ch. But a 8-channel radio will do 16 with no problems) The Frequency entry range has been extended from 0 MHz to 999MHz. This means you don't need the key when entering out of band frequencies. The encryption when writing to disk has been disabled. The "CRC" check (checksum) for gp300.mdf file has been disabled. This lets you play around with the gp300.mdf file without having to do a checksum every time. The software now lets you read a radio or file then clone the information to another radio using the F8 key (all aspects of radio will be cloned including serial number, model, freq range etc). All radios can only be extended a little bit out of their freq range. So don't get any crazy idea's about getting VHF radio to work at UHF. Finally I would like to thank Batlabs for the information on their Webpage. Without that information this cracked software would not be possible. Also thanks to Steve in England for testing it out on his GP300's. 73 de gp_300@hotmail.com
