VERY GOOD THANKS
HOW ABOUT A PARTS LIST, NO VALUES IN PRINT

Is there a description and installation instructions for this mod?
Does someone actually have circuit boards that can be purchased for this?

If I wranted to build a circuit like this one is there a software to help me layout a perfboard for the circuit.? I have LTSpice but I don't see anything to layout a perf board in it. It just may be that I don't know where that feature is in the software.

Lt Spice is a circuit
simulator.? Not for Layout of PCBs.? Use one of the online PCB
programs folks have been discussing here on the group.? Look
back through the posts on PCB Layout Software.? Any of them
will require a learning curve.
For instance, that
circuit uses some small SCRs.? Not a real popular part, you
might get to make the Model (s).
There is a schematic
model and its matching PCB model.? Start with the schematic
program and create a nice schematic before going to PCB.? It
will transfer its connections (netlist) to you PCB.?? It will
find many mistakes (inconsistancies between schematic and
layout).? If you are real careful, you can make PCBs that are
correct the first time!
PCB layout is Really
Fun!? Better than crossword puzzles.

Vince,
I have been laying out
PCBs for nearly 30 Years.? I have used just a few.? They are
really a learning curve.
There are some really
expensive packages that I have not used (Mentor?).? I would
put little faith if they claim great auto-routing?
You might get results
with an auto router, I never have.? I have watched it put
traces down until it gets in a corner.
Then it "Rips Up and
tries again", kind of sadistic to watch!
If you had lots of space
on the PCB, maybe let it go, and then? finish it manually.
The real secret is to
really spend time on a good schematic.? And when the Design
Check says "you got problems",
you better heed the
warning and fix the problems.?

Yeah that's kinda what I thought. I have a double sided board I'm working on that's only about an inch by an inch and a half and has 3 ICs on it. One sits under another larger one. Having a bit of trouble keeping my wits on this one.
Thanks!

Eagle and Diptrace have an integrated autorouter.
Here's a post on using Kicad with TopoR:?
? ??
The Freeroute package can also be paired with Kicad.?
Most of my time on designing a board is spent placing parts properly, setting up footprints
for new parts, configuring design rules, triple checking the netlist.? On any boards seen
in this forum, the actual trace routing is not very time consuming, and anything RF
is best done by hand anyway.? As a plus, time spent hand-routing is time spent
thinking about possible design errors.??
At work, we used Mentor's PadsPCB.? It had what's considered a reasonably good
autorouter.? Nobody bothered to use it much, results were not as good as routing by hand.?

Mike and the group,
I’ve found the autorouter to be both a blessing and a curse. Some of the higher ends models will do high speed data lines and so on. For what I’m building, I don’t have an issue with using them.?
Here’s what i do when autorouting ?a complex pcb.
Many times, there are traces that need to be in a specific location or must be extra wide because of current carrying requirements.
I lay those down manually, and then ‘lock them’ so the autorouter won’t rip ‘em up and try its hand at it.
After the autorouter is done, I go through one layer at a time and fix the mistakes the autorouter made with its creative routing. Electrically, it’s perfect, but it looks like crap. Sometimes a trace goes righ by a pad that it needs to connect, goes around a transistor lead and then back to the required pad.
?A human can cheat. Most autorouter do the top layer one way, the bottom layer the opposite way. I can go in and break that rule and run the normally vertical top layer horizontal. Of course you can select what layer does what direction, so this is only an example.
Sometimes I feel the autorouter’s sister is the same woman that does GPS navigation, they both can be creative!
and yes, it is sadistic to sit and watch the autorouter try and try and try to route the pcb.
However the biggest problem I see in autorouters is the ability to re-route the board time after time quickly. If you had to do it all by hand and it took days to do, you’re more likely than not to rip it all up and start over just for grins.

By the way, I see a
lots of requests for Package Layouts, pre-done.? People really
worry too much about that.
What they should worry
is how hard is the learning curve for making your own packages
and schematic symbols.
I almost always make
my own packages from the IC drawing or what ever I am making a
model for.? Most packages that come with the Layout software
were done by someone other than an engineer or someone
familiar with layout.
I always try to have
Pin1 at 0,0.?? No matter what the outline around the part is,
always try to make a pin (1) the reference point.
Jerry didn't not
mention what the cost of Pads was, I bet over $10K.? And maybe
another couple K PER YEAR to keep the license up.

Jerry didn't write the check, but that's in the ballpark for a fully loaded license.
I was encouraging them to look at other tools like Eagle, and later Kicad.
I like cheap, and would also prefer to not use anything stuck with MsWindows.
But folks there have a history of using PadsPCB going back to the 1980's,
and inertia is one of the elemental properties of the universe.

I'm thinking of doing a PCB for this but have a query about it's operation.
It seems to me that any detected fault turns on Q5, which in turn turns off Q1, which then has the effect of bringing up the 'Operate' LED D1 rather than the 'Fault' LED. ie they seem to be swapped over.
Has this Schematic actually been built and tested?

There are some missing parts in the BOM also, C10 & C11. I assume 10nF (0.01uF)

I only see one 62R resistor. I assume you mean that one is 68R ??? C10 & C11 are not in the bill of material.
Did you see my other post re the apparent reversal of the 'operate and fault' led's?
The reset switch does not reset the SCR's. Only the astable.

No boards available… I designed it for a friend and as I said in my original post… it was prototyped and proven to work… but I had no desire to build boards (I want to finish the antenna tuner first).? If someone wants to provide boards, please, by all means do so… the circuit is public and for your use and modification.? I uploaded the DipTrace file I used to create the schematic to the “K9HZ Projects” files section here in the BIT20 Group.IO group.? I didn’t pay much attention to the part footprints because I just wanted a quick schematic… so beware that you need to check each part for its dimensions.? The actual part values are in the EXCEL spreadsheet that is in the files section as well…? So far it’s saved a couple of radios (or so it has been reported to me…). ? ? Dr. William J.
