Why you are a spammer????
There are so many threads about goldgun and you put the photos of your here...

It is the frequency of oscillator.
LRL has two detectors, one for magnetic fields and one for electric fields. With the magnetic detector it located a big object from 70m with very strong signal.

Is the oscillator for transmitting a signal? You see, I don't know much of anything about the pistol detectors. I thought they have a transmitter (the large coil) and a receiver (the ferrite rod). So I can only guess the oscillator is a transmitter.

[Geo]

At my lrl i use the oscillator only as signal sample.

[Mike(Mont)]

Again, I am illiterate on this but I assume that means something like the frequency discriminators.

[WM6]

So I can only guess the oscillator is a transmitter.

Oscillator circuits can serve as both: as transmitter circuit (active oscillator) and as receiver circuit (passive oscillator).

In general oscillator circuit is tuned at desired frequency (which is "pass through" for desired/tuned frequency and all other undesired/untuned frequencies are damped or, as you say, "discriminated")

[FrancoItaly]

My LRL is a passive receiver, the oscillator only serves to generate a reference signal which is modulated by the phenomenon. The phenomenon has undoubtedly an electrical component which acts on the antenna, or acts on an existing signal in the range 100-200 MHz, or acts on a sub harmonic in the GHz range.

[WM6]

Always internal (circuits) source of phenomenon (interferences, harmonics, mirroring, l/c coupling, unintended oscillations, unintended converting circuit - as par example from receiver to some sort of magnetometer etc.) should be excluded, before end-conclusion about external source of phenomenon.

Well, I actually think I understand what you are saying. It sort of drowns out the other "noise" and has constructive interference.

Is this something like the original Gold Gun and the AGR Receiver? Excite the target and it radiates a lower frequency?

[FrancoItaly]

I repeat, it is a passive receiver, there's no transmitter, the oscillator stage is not connected to the antenna, is the phenomenon that propagates away from the metal buried.

[Mike(Mont)]

Go look at Accurate Locators the AGR receiver is passive. Appears to be same as Gold Gun only tuneable.

[FrancoItaly]

The fact that it has the highest sensitivity in the direction north south suggests that there is a connection (if not directly) with the Earth's magnetic field and the compass effect partly confirms this hypothesis, in fact, if the gain is too high the LRL becomes a compass. One explanation could be the solar wind deflected by the Earth's magnetic field, it is a flow of ions that could esssere modulated by the phenomenon, but I do not have the skills to prove it also seems that the solar wind does not come to touch the earth's surface, for at least in measurable amount.

[Mike(Mont)]

Some of the wording in the AGR owner's manual is identical to the original Gold Gun. It might not be the same circuit, but the principle appears to be the same: Local AM radio stations excite the target and it radiates at a lower frequency. The part where it gets hard to swallow is for areas of no AM reception. You just tune exactly to a VLF station.

What elements does it detect? High conductive metals?
