Finally I received my ADT-200A and so far the first tests were very positive. I was able to compare on my Optibeams with my K3, FT-1000D and IC-7800. In my opinion the ADT-200A plays in the same class. And the modulation reports, which I received, are all excellent and in no way inferior to the K3. It takes, however, some getting used to operating the ADT-200A in comparison to conventional machines but all buttons and keys are very clearly arranged so that navigation is easy. Handling the ADT-200A can almost be done intuitively. But only every day use will show whether the ADT-200A's quality is superior to my other transceivers.
