Lrl from Italy

I don't think 358 adjustment is very convenient, in the circuit needs to be improved

[liudengyuand]

In the first few pages of BBS, useful 4046 production of the machine, it is what principle? Effect is better than with 8 m crystals? Who knows?

[FrancoItaly]

The performances are equal, with the 4046 version are measured the phase differences while with the version 8MHz quartz are measured the variations of amplitude. My initial idea was to compare the phase changes with the amplitude variations in order do get some discrimination but I have not found anything useful.

[liudengyuand]

How to measure the oscillation frequency of L1 and C10? I have no way to measure with the oscilloscope, how can we know that the oscillation frequency? Whether it needs to work in the resonant state. We need to further understand its principles

Hi all

this is my LRL

The result which I found I could reduce the effect of the compass only by reducing the threshold or the length of the antenna (not gain!)
There are many signals in the field in the ground behind the house at the village

i can centring one of them but I dont dig the ground to discover the goal (Because I wanted to make sure before that)

Congratulations

Hi sakher,

Good work, as I said for better sensibility and stability it is advisable to shield the box and the handle with a sheet of aluminum (one for food use) connected to the ground. You will notice that the sensitivity increases by gripping the handle with both hands.

Best Regards

What you write or ask for LRL???
Какво пишеш или какво искаш да научаваш за LRL системи ???

Пиши по Български и слет това със Транслатора по Английски .

only night working day does not work LRL 2

Защото (може би) само Нощното време получавате Честота на радиостанциите около вашия регион.
Дълги радио вълни (Khz, Mhz) през нощта, се
отразяват от слоя Ionosfer до земята.


Because (maybe) only Night time you Receive Radio Station Frequency around your region.
Long radio waves (Khz, Mhz) at night, get up reflecting from the Ionosphere layer to the ground.

Hello
Dear All.
I built CD4046+Pwer+display, but unfortunately its battery consumption is very high and don't work correctly with 2 or 4 9V. Do you have any suggestion for solving this problem?
What type of battery or power do you propose?

Hello Franco The predecessor should be vertical or horizontal

Wht's you mean for "predecessor" ?

The coil is horizontal, but perhaps it works also vertical.

Franco What is the best voltage?

Post the wiring diagram, I cannot understand which one you are referring to, however the alternative to the variable capacitor is a varactor.

Varactor value?

Sorry brother,l using mobile phone
