In November of 2006 we turned-on the first Icom D-Star repeater in Indiana. It was first put into operation the UHF package and the 2 meter band package was added a few months later. With this new digital technology in communications a whole new learning curve was required in how to test, trouble shoot, and the addition of RF amplifier problems has caused us to think in a different way then we have in the past. We are learning everyday more & more about how to improve the digital system and are really looking forward to what this new mode will provide as time goes on. The Gateway was added to the package on 5/9/07 and the addition of other bands will happen as installation of antennas become possible. The interest in this new type of communications mode has been quite high here in the Indianapolis, Indiana area with over 30 users having equipment to operate the repeaters within a week of it being put in operation. Even though we are still in the very early stages of the installation of this new mode it has shown that improved communications is possible.
The 2 pictures of our D-Star cabinet shows both repeaters, controller, UHF cavities & pass filters, receiver pre-amps, Gateway computer, 2 power supplies and PA decks that make up our digital machines. The picture of the rack frame with all the splitters, duplexers, & cavity filters (located in the adjacent room) is what we have installed to operate our 442.650 analog repeater along with some radio stations 5 Marti receivers and also the combining of this 2 meter D-Star repeater with another antenna utilized by the radio stations at this site for VHF communications. Only the 2 larger cavities at the bottom of the rack and the 4 port pass filter on the top are needed for the radio stations requirements, all the rest are for Amateur equipment we have installed at the site.
