H. Phinizy, k6whp Funny you should ask about the Genesis radios. They are the only code plugs that I've really looked closely at. The HT600 and P200 (except low band) are the same radio. The HT600E, MT1000 and low band P200 are the same radio. I have no knowledge of the HT600 code plug, but the MT1000 code plug is straight ASCII text characters that are positioned at specific byte locations in the code plug. My interest in cracking the code plug is because I have several MT1000s - a 16 channel UHF on GMRS, a 99-channel UHF on mixed use, a 99 channel high band that is loaned out, probably never to be seen again (the guy dropped out of sight), and a 99-channel low band 42-50 MHz version that I'm still trying to move to 6m while maintaining sufficient RF bandwidth to do both 47 MHz Red Cross and 52-53 MHz amateur repeaters (yes, it will take two different antennas). In other words, 42-50 will preferably become 46-54, but I'll settle for 47-54. Once I figured out enough of the format that I was convinced that I could use Notepad as an editor I lost interest in going any further. I've taken a UHF MT100 code plug and edited it to move blocks of frequencies around. The radio started out as a mix of channels and I eventually ended up with amateur simplex at the low end, open repeaters above that, closed repeaters above that, and the last 10 channels were GMRS. I simply limited my edits to line 15 and down, moved the blocks and fixed the first four characters on leach line. A year or so later a friend heard about my efforts and sent me his "cheat sheet", that I combined with my notes to produce the test below.
