“The Electronics Of Radio” NorCal 40B Transceiver Build Lab Notes: Problem 4 (Also An Interesting Way To Simulate Amplitude Modulation In LTspice)
This is a continuation of my solutions to the problems contained within “The Electronics of Radio” text by David B. Rutledge. These posts are probably only useful if you also are following along with the book and building the transceiver. [Update: The links to all problem solutions as I go through them will be posted …
How To Build A Simple Single Transistor Amplitude Modulation (AM) & Demodulation Circuit (With Explanation Of How It All Works)
I ran into a roadblock. I am systematically going through “The Electronics of Radio” text by David Rutledge and answering the presented problems. Aside from buying the NorCal 40B transceiver kit, I have been able to use only equipment and components I have previously acquired for the first three problems. I hit a wall on …
“The Electronics Of Radio” NorCal 40B Transceiver Build Lab Notes: Problem Solution Links
This is a list of links to each blog on the problems presented in “The Electronics of Radio” by David B. Rutledge (1999, 2008), a textbook that uses the NorCal 40B Transceiver kit as a backdrop for learning electronics. Keep in mind that I am a novice and these solutions may be, and in many …
“The Electronics Of Radio” NorCal 40B Transceiver Build Lab Notes: Problem 3
This continues a series of blog posts on David Rutledge’s text, “The Electronics of Radio”, that I am studying while building the NorCal 40B transceiver. This series of posts will not be a review of the book, nor is it a assembly manual. Rutledge presents a series of problems at the each chapter that aid …

“The Electronics Of Radio” NorCal 40B Transceiver Build Lab Notes: Problems 1 & 2
This may be a series of blog posts you choose to skip over. I am following David Rutledge’s text, “The Electronics of Radio” while building the NorCal 40B transceiver. This series of posts will not be a review of the book, nor is it a assembly manual. Rutledge presents a series of problems at the …
Adding A Servo Winch To A Vanquish VS4-10 RC Crawler (And Testing Voltage, Current, And Pulse Width Modulation Signal)
So… I told you I picked up a new hobby. I can’t even remember quite why exactly, but right before Christmas, I got it in my head that I wanted to get a radio controlled truck known as a “Crawler”. The name refers to the fact that the vehicle goes slowly but capably, i.e. crawls, …
How To Set Up WSJT-X With An Elecraft KX2 Transceiver For FT8 Using A Windows 10 Laptop PC Without An Additional External Soundcard (And An RC Crawler SOTA Adventure)
[Jump here or scroll down if you just want to get started with the instructions on how to set WSJT-X up on the Elecraft KX2 transceiver.] I messed up. I could not get the KX2 to transmit in SSB yesterday. On a truly beautiful spring afternoon AA1F, Georgie (our shepherd), and I set out to …
HamSCI Workshop 2025: A Little Bit Of Citizen Science-ing
[This post contains: my “fake” journal article which is actually a rather nice write-up of the very real work I have done if I do say so myself, a printable copy of my poster, and the raw and processed data from this experiment. I am putting it all on here because of the interest that …
