Modifying old LRLs

[Mike(Mont)]

Good news, Geo!

Hi Pahom.
I don't remember the number of diodes now but i think that it is D9B. I tried them on a crystal radio and they had better sensitivity with more clear audio. There is big difference between them and 1N60 or IN914 or AA... that you find on ebay.

Pahom.. i checked diodes, yes D9B.

I understood you. Previously, they were put by d9B a red stripe or two red stripes or red dots. Then he refused. Ask Kostas Russian d9b sent him something like that. If he didn?t spend them all.

No problem with D9B, i bought 100 pieces before 3..4 years..

Pcb at right is an equaliser (schematic by Esteban). I plan to deconect it because i did n't see it to doing something better
Also i plan to connect a potentiometer so to reduce the gain at places where there are strong magnetic fields, but i did n't decided how to do this.... by playing with the receiver pcb or by connecting a potentiometer in series with coil....

Good news, Geo!

Now i am ok... i have eagle's eyes...
Yesterday and today i visited my lab and finished the mod of PD. Results inside the lab are fantastic... it has at least twice and more sensitivity. If outside the lab be stable then will be a lrl near the top of all i have.

what are the other modifications Mr Geo ?

as i wrote at previous post i replaced in60 with d9b.
also i gave a little pore power at stimulator oscillator. i wanted to connect a one stage preamplifier on coil but sensitivity is so big.
frequency of Rx = 62khz and from stimulator 125khz

Happy New Year! It's good that everything is fine with the eyes! Tell me, in this variant of RX -62kHz and TX -125kHz, which registers better Argentum or Aurum?

[Geo]

Pahom Happy New Year for u and for all members!!!

Sorry but i don't understand what u mean with ""which registers better Argentum or Aurum""

In your experience, these frequencies are what kind of metal they found more.

[Geo]

from my experience.. nothing... but before years i readed a research from a univercity where gold "responded" better at frequencies near to 62Khz. Also Alonso was ues this frequency often...

Thanks Geo! Maybe you have information and RX frequencies for silver!

[Geo]

Before years i had a file with all these frequencies but i didn't find it.
Maybe tomorrow to give a second try...
