I just got back about 20 minutes ago. Still no sensible answer to my
question about the fsd.... :-(

You are only doing an ac simulation of the circuit and you're only
measuring the RF voltage across the meter. RF is not going to drive the meter.
Only DC will make the meter pointer move.
Do a transient simulation of the circuit and look at the end conditions
after the circuit has been running for several seconds.
If the answer to your problem doesn't jump out at you, let me know and
I'll walk you through it.

My Christmas has got back on track again. Jim,
I'm grateful to you for your interest in this circuit, but your
representation of it on this page is quite frankly baffling. I invite
anyone without anything better to do this Xmas (like Jim and I, by the
look of it) to compare my schematic with Jim's representation of it
and spot the differences...

Sheeesh! One does presume you wanted a DC current in your meter, thus
the added capacitor, C2, across the meter.
The added diode makes it work... take note of the comments... D2 OUT =
your circuit, NOT FUNCTIONING, D2 IN, it works.

Well I hope you're wrong, Jim, as I'm one diode away from completing
the thing (and I've even etched a board for it, too)

Have you performed a TRANSIENT simulation in LTSpice?
I find it hard to believe that Mikey's transient response would give
incorrect results... unless the "quicky" diode model doesn't do well
at 40MHz.

Yes sir. I even run one 'til my hard disk filled up with the pS-by-pS
record of it and the whole computer came to a grinding halt.
Just remember, if my circuit works in practice, I own your ass.

What's the definition of "works"?

Paul's posting on his web site shows that the *did* do a transient run.
For all of 10 nanoseconds!

Aha! I guess I should have paid closer attention. My simulation ran
for 25us with 1ns steps.
Paul is certainly in for a surprise ;-)

James,
Somehow I missed Paul's simulation and can't find reference to it in
the thread. Do you have the URL?
It's puzzling that he ran for so short a time. The PSpice sim only
took 6 seconds.

I'm off to the pub.
Our night started at the local watering hole, then ended with joyous rides
on plastic saucers pulled over fresh snow behind a VW Golf at 40 km/h.
Ahh, the holidays!

You guys are in for your own surprise. | got up to 15mS today before
the computer crashed. I'm gonna own *both* yo' asses (as you say in
the US according to all the movies I've seen).

Ah, yes, movies! SO REPRESENTATIVE of how things really are here in
the good ol' U.S. of A ;-)
25us (that's MICRO-seconds) will do quite nicely. Please post the sim
results... maybe I can snag Mikey at the same time ;-)
