Yep just one how the heck do us it LOL
I did this but can't figure to save my life how to set the parts.
L1 is a antenna couldn't find nothing else I'm taking the reading at R1 with a DVM set on 200 mV it works in real life to read
RMF from lights cill phone microwave things like that. I know that the read just mostly tells you there is RMF waves I guess
It works Tv it show 14mV not near nothing 0 mV walkie talkie off the scale 500mV microwave 50 mV

You can not leave a part not connected. L1 for example. 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. Green is the input. Red is the output.
119569
To see the voltages, after "run" (the picture of a man running) click on a wire.

Sussed it out....
Copy all of the text from the link above in post #6.
Paste it into a new text document and save it as "standard.dio".
Replace standard.dio in your program_files/LTC/LTspiceIV/lib/cmp folder.

Was just going to suggest that, but you posted.
There may also be other devices in that link, that you want to add.

Regards.

I just tried it on Win10 and I do not have permission to do that. I have done that on all other Windows versions.
I'm still on win 8.1, maybe Burt's file edit can work?

You can not leave a part not connected. L1 for example. A antenna
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.

"voltage" almost last thing. Then go to advanced and fill in voltage (which is peak) and frequency.

Select 'component' and scroll to the right, to find 'voltage'.

EDIT: also, please indicate an edit to your posts, otherwise it can become confusing.

I'm using windows 10 the latest copy I can edit the standard.dio I didn't try to add the whole list http://ltwiki.org/index.php?title=Standard.dio
I figured out how to find V1 you use the F2 key and a window pops up LOL
Thanks to Ron I know how that works and thanks to Mick I now have a 1n34a in there LOL

Ron do you have these C:\Users\YOUR-NAME-HERE\Documents\LTspiceXVII
If so you can edit those files

Thanks I was trying to edit c:\Program Files\…… like we did years ago.
In Win10, LTspice instals itself by default in the Program Files path, but also copies to the .....Documents path. When running, it only seems to look in the Documents path.
