The owner flew it into the side of a barn, and survived. That story is fully detailed in my blog, along with some additional pics. The...

STOL Magnificence. Takeoff and landing performance is enhanced with a wing that has a high coefficient of lift. What this means is that...

Perhaps the best Belite built, ever.

I was asked for more construction details on my STOL ultralight. The fuselage is built from aluminum sheet, angle, and honeycomb...

If you are interested, contact me via FB DM or via jamespwiebe@gmail.com This ultralight first flew in 2019, and was originally a...

Gotta pay the bills. I've decided to sell this ultralight. The fuselage and tail feathers are old, however the wing build is new (2025)...

2025 provides me with the opportunity to share my love of aviation. In 2017, I designed "Chipper 2", which has become a famous ghost in...

A while back, I documented my long distance listening of a commercial aircraft using SCARP. I recorded what I heard and I then referenced...

I'm talking about how to analyze the efficiency of coupling to an antenna. I'm picking up from yesterday's post. Today, I'll add a couple...

A VSWR meter is a device which allows you to measure the "transfer ratio" between your radio receiver and the antenna. It is the measure...

Today I created a quick demonstration video of the sensitivity of SCARP using a moderate signal. I then step the signal strength down...

Recently, we received comments on our Facebook posts that everything SCARP was doing could be done by a cheap Chinese scanner or perhaps...

Last week's update included how I'd become dissatisfied with the bandpass and Low Noise Amplifier (LNA) which is embedded within my...

In the latest PCB version of the SCARP receiver board (Arduino Project for Software Controlled Aviation Receiver), I couldn't get the...

I've been designing a multi-channel aviation receiver, with amazing sensitivity, selectivity, audio quality and overall usability. The...

I've made great progress on the Arduino project on Aviation Radio Shield. It monitors eight aviation channels, providing fantastic...

I wanted to create an Altimeter / VSI instrument which would work great and be inexpensive. What could I do to make it stand out? Here's...

If you're looking for "software defined radio" (SDR) or Arduino, you might want to keep close tabs on this development.
