If you are a hobbyist and interested to know the evolution of radio/electronics for the past 50 years, you are in the right place. Don’t worry, I will not bore you with well-known history, which has been detailed in many good books. Instead I will give detailed circuit description to the radio receivers/transceivers I have built, from simple to complex. I will also describe the architectures and circuits of some landmark products. I will trace the developments that leads us to the present day designs.
Posts related to radio receivers/transceivers will appear under Nostalgia page. I will also include some proven construction projects that are useful to hobbyists under the Projects/mods page. Last but not least, I will discuss test/measurement and equipment repair under the Vintage Equipment page.
I will keep updating this blog by constantly adding new posts. Stay tuned.
