What similarity ?, what differences ?

Receiver transmits

Hi Esteban
For Tx I mean a oscillator that drives a coil and then there is a magnetic field near the instrument. I think that it's necessary to have a stable Rx signal with a single operative frequency.

Actual "discovery" (maybe I'm wrong, regarding discovery or not-discovery) show that any passive receiver emits in the frequency tuning. But this can measurable with no contact scientific frequencymeter. Today I saw in Alonso's labo! The emission is short, maybe only 7-8 cm. For example, if you touch the tuning coil or connect oscilloscope in it, the low level emision vanishes.

That's right. But as you may know, there's one measuring aproach which overcomes this issue. But of course, this is secret.

This is part about how the "phenomenon" can be detectable via "passive" (now active?) receiver.

P.S.: I have confirmed by Alonso that the "new DCH" is the pistol detector called "Oscilador 2000".

Hi Esteban
I remember an old instrument, a Grid-dip-meter, used in order to determine the resonance frequency of a tuned coil, without some electric contact. the tuned coil it absorbed some very little energy from tube oscillator and it caused a change in some parameters of the instrument. This was possible for the very high impedance of the input grid tube. I think that a coil tuned on a high armonic of a oscillator acts as a sort of frequency converter, that's it can translate in a lower frequency any change of the high frequency. For Morgan I am a lot interested of Damasio'book but I don't think that it's possible for me to obtain a English translation, however I thank you.

I think that the device used is not a dipmeter. A dipmeter consist in an oscillator. From Wikipedia:

Grid dip oscillator (GDO), also called grid dip meter, dip meter, dipmeter, or just dipper, is a measuring instrument to measure resonant frequency of radio frequency circuits. It measures the amount of absorption of a high frequency inductively coupled magnetic field by nearby objects. It is an oscillator whose output energy changes in the vicinity of a resonant circuit which is tuned to the frequency the oscillator generates; somewhat similar to an acoustic tone becoming louder when generated in the vicinity of a resonant cavity or a string tuned to the same frequency. At the heart of the instrument is a tunable LC circuit with a coil that serves as a loose inductive coupling to the measured LC resonant circuit. Resonance is indicated by a dip in the meter indicator on the device, usually based on a microammeter.

Hi Esteban
My idea it's that Grid dip meter explanes as a tuned coil can influence another coil some cm away. However electromagnetism laws they explain the mutual infuence between 2 coil.
