This book includes useful tips and tricks for the configuration and operation of the amazing Yaesu FTDX101D and FTDX101MP transceivers. Rather than duplicate the manuals which describe each button, function, and control individually, I have used a more functional approach. This is a "how to do it" book with easy to follow, step-by-step instructions. For example, I describe how to set up the transceiver for SSB operation. Then I follow that up for CW, FM, RTTY, PSK, and external digital mode software such as FT8. The aim is not to replace the manual but to more fully explain how to configure and operate the radio to take advantage of its many great features. For example, when I cover the front panel controls, I explain not only what the control does, but how and when to use it. Along the way, I offer a few 'tips' on how I configured my radio. You don't have to follow these suggestions, but they provide some guidance.The FTDX101 transceivers have superb technical specifications, and the FTDX101D currently holds the top position on the highly regarded Sherwood Engineering transceiver performance table. The book covers both variants of the transceiver. The FTDX101 is a truly exceptional radio for contesting or working DX stations. Learn about the dual receivers, the band scope display, and the new FT8 Preset. This book will help you get the most from this complicated transceiver.
