Don't do it! The 2200 with the DV card in it is still brain dead. Just a handful of channels. Save your money and buy the 880! Or plan to end up selling the 2200! 73, Tom n4zpt On 2/13/2010 10:23 AM, Don Bowen wrote: I am trying to decide between the Icom 2200H or the Icom 880. The 2200 is

to see a slower speed DD mode we could use on lower bands. Might be an improvement on 9600 bps packet on a band with better propagation than 23cm. 73, Tom Azlin n4zpt John Hays wrote: Hi Ron, There are two data type services on D-STAR. The first is part of the DV (Digital Voice) mode. The DV

Nope, the Icom DD mode is 0.5GMSK just like in the DV mode. Just higher data rate. If you had fast enough switching on the amp you could probably use class C amps since this is just Gaussian filtered minimum shift FSK, i.e. FM. Same as for the DV mode. 73, Tom n4zpt Jonathan Naylor wrote:

Hi Steve et al, I thought there was not a part 97 defined CW subset of the bands except on 2m and 6m. Rather is a sub-band for data and a sub-band for voice and image based on content not modulation format. With CW allowed everywhere (but not tolerated by many hams) but the anomalous 60 meter

Hi Manos, I am not sure exactly what you are trying to set up. But this is what worked or did not for a group of us here in Northern Virginia. We do not have our local gateway up and running yet. But in prep for the 2006 Marine Corps Maration we were not able to have two distant ID-1s that
