I suggest that if your group can get hold of commercial quality especially Motorola repeaters and accessories, that is the way to go. They ain't cheap! If not, then unless you have four or five experienced electronic and communications types with a room full of service monitors and other commercial grade test equipment, the best thing to do is to "write a check" for a system produced for amateur use. The idea of building a state of the art system - or even just the computer card for one - is no longer practical. Of course if you just want to fool around and don't care how it works, then you should please yourself. If on the other hand, you want a system which you know will be up day after day and year after year, then I suggest you follow the above. My group which includes the aforementioned experts and equipment has built up a system which we think is pretty great but it doesn't do half what some of the new commercial systems in the back of QST or 73 magazine now do. In addition it is a weekly maintennance job for three or more men to keep it on the air. We do this because we think it's fun but perhaps you would not. In brief, it is far easier to raise a few thousand and put up a turnkey system than it is to design, build, and maintain your own system. This is perhaps not what you would wish (nor do I) but it is the truth. As to the system you should choose, I suggest you check locally to see what other groups are running and go look at the stuff yourself. Lots of luck! Bob
