Wait, you are telling me that you can't offset the trigger horizontally?

Oh... you are using the analog scope sim. I forgot, sorry. Still, there might be a "delayed trigger" setting in there somewhere.

I wonder what the triangles at top left are for, then.

Dragging them has no effect because, unlike a real scope, moving those llines neither increments nor decrements anything.  Sort of worthless in that respect and they don't hide anything either.

WOW, I can't explain it but the kicking worked.  It increased the current it was giving by a LOT too.

About to put up another video so hang tight.

It is weird and nothing like what the real device does. Your collector trace is flat at the battery voltage, it seems, so the circuit isn't actually oscillating, or you aren't catching it with the scope settings you are using. What you are showing now is very similar to what you had right at the start of the thread, with the positive/negative symmetrical sinusoid, isn't it?

How come you've disabled embedding?

Almost but not as symmetrical as that and the MPSA18 is backwards also channel A is on the base not the collector.

I don't know what you are seeing in that signal but it's not anything like a JT oscillation nor what I see with the reversed transistor. Look at my scopeshots, you'll see that I use the same timebase and vertical settings for both the correct orientation and the reversed one, far faster than your 5 ms per div.

Your scope in the video is set to 5 milliseconds per horizontal division, right? So the signal you are showing is at _exactly_ 500 Hz! It is less than 2 microvolts in p-p amplitude. This is not the circuit oscillating, it is a sim artefact, probably.

Look at the bottom left of the screen where it says "x pos. (Div) = 0" Try changing this to "3" and see if the trigger point moves over to the right.

It does but not those cursors.

OK the cursor controls are probably the arrow buttons T1 and T2 at the left, just below the trace display window. The cursors should be vertical lines, and the position in time relative to the trigger point will appear in the window to the right of the cursor buttons once you move them off the zero line. The voltage levels where they intersect the traces will be listed there too.

Correct and the point under the cursor that is moving shows you the time, and values of channel A and B that is under the cursor being moved but in a T2-T1 way.  So, move T1 and leave t2 at pos 0 and get negative numbers vice versa will get positive numbers.

It is _still_ oscillating. It has stopped a couple of times but always restarts with a "tickle" across the emitter and base with a bit of wire. The frequency right now is 666 kHz, I kid you not, and the battery voltage is 330 mV.

Did the scope arrive yet? I forget, what kind of scope did you order?

Only a BK 2120 with everything in their original packaging with the original manual shipped in its original box.

My fear is that if/when it finally shows up it will no longer be 100%.  I mean it was doing something for those 4 days and normally when that happens the USPS has messed up the package somehow.  From NJ to Memphis is a 3 day, max 4 day, USPS trip but just look at the tracking.

Lol, at the 666khz.

Ran off of a battery?  The lower voltage tells me it is probably draining more current and giving, or trying to, more current to the LEDs.

Scope is in limbo land again as no new updates YET again.  I figure they drove this scope from NJ to CO and are driving it to here with no airplane usage at all.

Honestly I so hope it never arrives now so I can just get a refund but watch it arrive the last day.
