Superregenerativ modtager

Den kan være svær at benytte, da den let går i selvsving (den "hyler"). Selvsving undgås ved benytte quenching. Kun én transistor/elektronrør anvendes normalt i radioforsatsen og den har lavt strømforbrug.

However this kind of reception is still much used professionally: millions of units a year are produced for miscellaneous applications as remote control, supervision, alarms, medical apparatus, etc., with contributions of new techniques as surface resonators (SAW) and up-to-date semiconductors..."

Tesla's Power Receiver Citat: "...The truth is quite strange...By manipulating the EM fields, we can force an electrically-small receiving antenna to behave as if it was very, VERY large...In theory a tiny loop antenna can work as well as a longwire 1/2-wave antenna which is 10KM long...The energy doesn't vanish, instead it ends up INSIDE the atom. By resonantly creating an "anti-wave", the tiny atom has "sucked energy" out of the enormously long light waves as they go by...When all is said and done, our oscillating coil has absorbed half of the incoming EM energy and re-emitted (or "scattered") the rest..."

In both instances, the target area a particle presents to incident light can be much greater than its geometrical cross-sectional area...."
