Digging deeper, this practical resource shows you how to engineer innovative devices by experimenting with and radically improving existing designs. Build Your Own Transistor Radios “This is the perfect guide for electronics hobbyists and students who want to delve deeper into the topic of radio. Overall, this extremely well written and comprehensively illustrated guide and reference deserves a place on the inquisitive radio amateur's bookshelf.� � QST “I would definitely recommend this book to novices and all hobbyists and engineers who have not have much practical exposure to radio design and development.� � EDN Make Great Stuff! TAB, an imprint of McGraw-Hill Professional, is a leading publisher of DIY technology books for makers, hackers, and electronics hobbyists.
I was naive enough to try to build the TRF radio circuit on page 57 in this book. It did not work. It can't work. The NPN transistors in this circuit need to be supplied with 0.7 volts in order to switch on but receive no volts at all. So the radio cannot work. Ronald: you are selling your books on the false premise they are good for hobbyists. This hobbyist tried your circuit and it did not work. Ronald you might have dozens of patents to your name but have you actually tried to build this radio?
