Temperature, the best friend of LRL's

[Esteban]

Hi,
hmmmmm.... are you sure it is ?

the voltage regulator and lm386 amplifier are quite intuitive...

also transistor thing and coil there...

the problem is that "seems" there is a digital IC there... cmos kind, 4000 family

So... if cmos/4000 and not HCmos... you know it doesn't go high in frequency...

The rx can be FM range... no problem running around 100Mhz... but I dubt middle stage is some FM thing.

BTW Esteban wrote "RF" not "FM" this time.

As always... he posts stamp sized pictures... and people start making wild guesses!

Kind regards,
Max

No!!! Many times I wrote "RF"!!!

[Max]

No!!! Many times I wrote "RF"!!!

?

this time you wrote "RF".

But other times you wrote "FM"...

not to talk that many LRLs stamp sized schematics have germanium diodes used for amplitude demodulators... so AM also...

And then ?

Lot of words... lot of funky pictures... stamp sized circuits and no facts.

Kind regards,
Max

Maybe, but i think it is some op amplifier or even a receiver ic.

Anyway the principle is always the same: receive rf noise and detect fluctuations.
All Esteban´s schematics are based on this principle, from khz to IR light

Because you're very concentrated in words "FM", but you can found in dozens of posts I use "RF" words.

RF ?

Ok, RF... fine for me. And FM, fine too... and even AM if you want!

Then?

As always... silly game with words... bits of informations... and some germanium diode for RF!

Don't change that there aren't facts about LRLs.

Kind regards,
Max

No.... seems much a digital IC.

Digital ICs can be used also for analog stuff/functions...

But maybe he will tell us...

(well... probably not... cause it's maybe some LRL secret! )

No, that´s me. I use RF word
Just kidding,
Are you going to tell wich IC is that?

I think the best friend of LRL is the light of the Sun.

Hi,

For me, the sun itself is the best friend of the LRL because it acts like a sattelite.

Hmmmmm...

geocentric in 2009 ?

within few time... we'll see also some creationism here and someone will say that Earth is flat and blood transfusions will mix different souls!

Something is wrong here...

Or maybe people time travel back some hundred years before have the illumination and wrote that pearls ?

Kind regards,

waw! esteban these last circuit is very simple, i understand these need other altern circuit for help,what distance detect objetives? what advantages and vantage? i think the sound is strong and progresive, major what beeper, i have ideas for build one major lrl, i have one bfo, have you one diagram for simple fm whit valves? whit 2 bulbos'? i need urgent these for build my project, i have one radio am and short band, work 125 v. radio ld, how many turns in coil anten i need? thanks for advance dman
soon i send photo of chasis whit big cristal valves, is extreme sensitive

Do you see a germanium diode on the PCB? I don't!

Do you have "contact" with donkeys? This can cause pain to you!

[Esteban]

No, that´s me. I use RF word
Just kidding,

Do you think can be a hex inverter?
