There is not a particular frequency, the operation of my lrl does not require the presence of a radio station.

I greet the members of the forum ...
I ask forgiveness for my English ...
After trying enrolled in forums ...
My turn and I publicly thank Franco to manufacture.
I am an amateur in electronics and maybe I can not give precise information
to the members who they asked me in my email
But I can upload my work and experiments I did and maybe some help ...

Hello franco. I build your lrl based on your pcb. All the components are based on your specifications. However, i do not have the voltage drop when touching the antenna, what should i do to have a voltage drop of 100 to 200mv. Capacitors c1,c2 and c3 are all 1 picopards. Please help me. Thank you...

You must follow my helps to avoid self oscillations.

[GOLDEN LILLY]

Does it mean i have oscillation when no voltage drop when touching the antenna?

Yes, if the stage is self oscillating it is not affected by touching the antenna.

HELP

a problem has occurred in my Franco LRL, I use two rechargeable battery 9 V and a regulator 7812, every time I set the threshold and the gain, the sensitivity decreases alone, and I will be forced to increase the gain every 30 seconds, is there someone who has had the same problem ???

[abdou2014]

the 12v power supply is stable, test with voltmétre, but the led goes Off alone after each setting ???
