I like your write up, BUT, there is something missing here. Are you switching from 5Khz deviation to 2.5Khz deviation while doing your test???
D-Star transmits at 2.5KHz, not 5KHz. There is a difference there... Focus needs to / could be with 900MHz equipment since it already does 2.5KHz bandwidth, even though the lack of 900 gear, though I would also like to see a 220 D-Star too, lots of band but lack of equipment. Heck to make it worth while, for the HSMM junkies, why not have a 1.54Meg BW 220MHz ID-220 ??? Think about it, 2.4 has too much part 15 noise to say, but bring it down where the Fresnel zone does not become an issue.... LONG DISTANCE HOPS that are NLOS or NON-LOS for Emcomm use, NOW YOUR DOING SOMETHING!

Hello, As part of our Dstar/Analog testing (see the thread posted several months ago) we modified a Mastr II repeater to transmit, alternately, Dstar and analog signals: For analog, we used the radio's phase modulator and for Dstar, we used the direct-FM on the compensation line. In our opinion, the Mastr II produced a better-quality signal than the IC-91AD, mostly because it didn't suffer from the "PLL Bounce" problem that the direct-FM modulated Icom radios have (e.g. associated with the PLL trying to track the low-frequency components of the modulation.)
