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.

To see the voltages, after "run" (the picture of a man running) click on a wire.

Does this help any?
Someone looking for 1N270, but a responder posted specs for 1N34A:

1N270 Spice Model

Does anyone have the spice model for the 1N270 Germanium Diode? I have found several online libraries of spice models for diodes, but none of them have the 1N270. A google search didn't find it, al...
electronics.stackexchange.com
 
Well i found this but a can't seem to add it
.MODEL 1N34A D(IS=2.6u RS=6.5 N=1.6 CJO=0.8p EG=0.67 BV=25 IBV=0.003 Type=GePunctualContact)
 
How do I add it tho I figured it out I added it to the diode file in ltspice cmp

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.

 
I got it to work I just added the
.MODEL 1N34A D(IS=2.6u RS=6.5 N=1.6 CJO=0.8p EG=0.67 BV=25 IBV=0.003 Type=GePunctualContact)
to the D standard file

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

Regards.
 
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.

"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.
 
Any one doing this on Windows10. How to save "standard.dio" I do not have permission and I am "Local Account Administrator". I can not change from read only.

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.
