Re: Ferrite loop antenna Part 2 Fundamentals, tuning, selectivity, and super nulls

Paul,

There are already several videos on YouTube showing how the use of a phaser and what it will do. There are also several videos showing the SDRPlay-duo operating in diversity and how much it will reduce noise and separate 2 stations on the same frequency.

Everett,

That's an excellent idea. Do you have a video on YouTube showing how to build an arrangement like that? 
My antenna uses very common items, cost very little, and can be built by most anyone.

If there is a simple way to use phasing and and diversity to achieve superior results I would like to learn about it.

It doesn’t make much since to use a tuned loop with SDR, it is taking several steps backwards. Go forward with phasing or diversity, both of which will reduce, or eliminate noise.
