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
After reading through the initial pages of the manual, I went ahead with installing the new MPPT Solar Charge Controller. Remaining pages were meant for setting up grid
LB7UG had been actively discussing on YouTube regarding optimization of my Easy BITX build. Today I am trying out a modified version of the VU3GAO Easy BITX dual
In an SSB (Single Sideband) transceiver like the Easy BITX, the Beat Frequency Oscillator (BFO) is one of the most critical components for ensuring clear voice communication and
