There is one thing Id like to know about ltspice

[eTech]

Next problem is I knew I needed the
But I can't find the V1 to add it But I took Ron's file and did change the diodes and sim it Thanks
Im look and see how the V1 is done now.
I don't know nothing about ltspice
Where do you find Voltage source to add V1 if you don't mined telling me.

Hello

You are asking a lot of really basic LTspice questions. Save yourself some frustration and try some tutorials. Check this link:

Yep but thanks to the simple stuff i could find i now can use it.

But ill have a look at them i would of never ask had i found the voltage source. The help file tells how to set it up but not where to find it. Like rotate it tells when you can but without hiting control r it doesnt happen
Then adding a model save in the folder
Cant find it add it to parts it worked like a charm.
Thanks for the link it looked like a good place to learn more adout ltspice

LTspice is a bit of an uphill struggle, but well worth the effort. A very useful tool.

It's after all the simple things that get you.

... A antenna connects to the world of RF and static. So I added a 1mhz 1volt signal source to make a signal for the receiver.

I have the feeling that if you get 1V at your receiving antenna, you are being way too close to the impact site of the falling satellite

Id say your right I played with walkie talkie that's .5 watts it was right next to it and it read 489 mV

Many years ago, crystal diode, coil wound on a toilet pater tube, 1000 feet of wire and I could get a loud signal from head phones.
I just looked up the station I listened to 50 years ago; 50,000 watts am. That explains why it would drive small speakers.
