Hi,
well I think that the wrong thing in researching for a true LRL system that work is the absence of any PHYSICS.
I mean, one could also build a thing that have a broadband amplifier inside... some antenna, some gnd plane etc etc but then hope that "the thing" can find something is pure speculation.
Speculative thinking, that is good e.g. in not-exact "sciences" like e.g. psychology or even also (sometimes) economics , is not any good or of any usefulness in any real electronic application.
Even e.g. fuzzy-logic devices have their rational thinking behind.
Speculative thinking is useful to test, try and find out new physics too... but then one must use scientific method to confirm theories, results etc etc then the theory stop being a pure hypotesis and become science.
People that want to find "the way" to real LRL must first read a ton of physics books and figure out if exist some kind of principle (or discover new by research) they could use to realize a true electronic LRL.
What we see here, about commercial LRL, are just claims... fake circuits... self-convincing thoughts... nothing really useful or working.
Once found A SUITABLE REAL PHYSIC PRINCIPLE application is often easy... actual technology, cheapy components and processes make manifacturing (often) a piece of cake.
Problem is related to existence of any good real principle and knowledge about it.
That's my point of view.
Kind regards,
Max
