In my last article, I explained how to measure the resonant frequency of an LC circuit by simulating a grid dip meter using an antenna analyzer or a NanoVNA. This method is convenient when you only have an antenna analyzer. However, a NanoVNA has two ports, and you can use …
In previous years, amateur radio enthusiasts heavily relied on dip meters as an indispensable tool for circuit testing. These meters are also known as grid dip meters. However, as of 2024, dip meters have become increasingly scarce …
