I'm proud to own one of the first ADT-200A. I could test the transceiver in the last days and it's really revolutionary.Some options don't work at the moment, but the main thing, the receiver works really great. This are not very technical statements, but all technical datas are on the webpage of HB9CBU (www.adat.ch). It needs some further development in userinterface but this concept is really worth to have a look on it.
