FrancoItaly does your LRLs detect a spark from 1.5V AA battery to 60cm ?
Have tested your hef4046 PLL-LRL version almost whole day. Very strange behaviour. Very lot of time to tune only for gold target. When find a gold signal device auto-lock on target. All 30 diodes have lit. Changing direction of stylus-whip antenna to any other side from gold target does not change nothing, with locked signal phase approximately 5 seconds, than after that immediate disappear or lock-off. Pinpointing work not when top of antenna is above the target but when a lrl-man is above the target with his back. Any human bio-field or human aura near lrl-man up to 5 meters and of course not possibile to detect anything. human aura suck golden signal complete.
I need to say i tune with 7 variable at once.
P1 vishay potentiometer 100k - 20 turns for frequency. With 5P variable capacitance and very low inductance cover over GHz range. Phenomenon also depend from frequency and many other variables.
P2 -ii- -ii- 1k - 20 turns for sensitivity, tune the ammount of signal comes mix with gold signal to C10 560P and base of TR2 BC183C, with beta more than 700.
P3 -ii- -ii- 20k - 20 turns for signal threshold at non-inverting input of ic2a lm358
P4 - ii- -ii- 10k oscillator amplitude adjust between legs 3-4 and leg 9 with viper to the input of C3 3n3. I can tune output pulse amplitude in microvolts range. Checked with oscilloscope. TR1 BF240 with own beta less than 100. TR1 has no biasing resistor 100k or more to common conductor.
P5 - ii- -ii- 10k FSD potentiometer tuning full scale display for 30 led diodes.
C11 variable capacitor 5p to 145p from old japanese transistor radio receiver, instead fixed 22p ceramic capacitor. Fine tuning vith big plastic wheel for tuning same radio.
L1 coil 3 turns wire 1 mm in diameter, left winding or counter clock wise wounded over 10mm drill bit. Tuned by stretching and compressing coil lenght.
stylus-whip antenna 1m long tuned to variable lenghts with telescopy.
ps. gold tuning or other metal tuning is frequency phase dependent.
ps1. sparking battery associate me with very low energy photons above the long earthed gold due to influecne of telluric waves. on some strange ways gold make unheard flicker photon noise deep under noise floor of background ambient field.
