Connected a temperature monitor probe to one of the two IRFP final MOSFETS of my homebrew VU2EVQ linear amplifier. Power to the temperature probe board was paralleled to
Very simple hobby project using a temperature probe and relay cut off. The cutoff temperature can be set in the relay using the preset push buttons. I have
In amateur radio, a panadapter (short for panoramic adapter) is a device or software feature that provides a real-time, visual display of radio signals across a wide band
Converted remnants of an old 4.1 music system and added a mic to make a home PA system. Originally it was working on a 12V AC transformer. Interestingly
The ionosphere is a region of Earth’s upper atmosphere—extending from roughly 60 km to 1,000 km above the surface—where solar radiation strips electrons from atoms, creating a dense
In the world of radio frequency (RF) and electronics, transformers and baluns are close cousins. While all baluns are fundamentally a type of transformer, they serve distinct roles
A DDS VFO stands for Direct Digital Synthesis Variable Frequency Oscillator. It is an electronic system used in radio transceivers to generate a highly stable, adjustable radio frequency
I had installed it when the Sun was not that strong yesterday afternoon. So I decided to watch the pattern of working and changes in indicators as well
Earlier I had adjusted Si5351 calibration by editing the firmware and reuploading the corrected value after getting the correction value with reference to my FT-710 radio as frequency
