That's great! Pulling out laptop as I write...
BTW, I found your "Mods for MD-9600" and did resistor mod right away. Well, it already had (SMD) resistor, cause my transceiver is HW V3, but it was 2.2k, so I replaced it with 1k. It was much better, but I even added one 22k resistor in series with speaker, cause I intend to use MD-9600 mainly at home, where I like to keep quiet environment. And it's easily removable/changeable, if needed.
Edit: didn't find that option...
