TH-D72A/E CONTENTS I Hams have en joyed using FM transc eivers for years fo r SSTV , A TV , p acket, satelli te, EME, GPS and other communication s modes. A fund amental reason for t his has been that FM transceivers are easy to use. Recently , personal computers and the Internet ha ve combined to offer global communicatio ns opportunities.
II CONTENTS TH-D72A/E Use of HF tr ansceiver to ca ll CQ and cont act to hams around the wo rld via iono sphere will never lose its appeal. But there is eleg ance in being a ble to communicat e with only an FM transceiver and by adopting the l atest technology .
