Yep, know all about that too, I'm preparing to downgrade because every plugin is disabled, and I at least need Session Manager to work! I won't do Chrome or IE, but open to other non-tracking browsers.

Are you willing to try an replicate my problem? If so...

Login to groups.io via firefox (not your email in firefox)
View this message thread
Hover over your prior URL's
Look in lower left corner of FF and see what the "real" hyperlink is now.

Does is have paired brackets for you?

If your running the new Firefox version 57 ...many things are broken ...many plug-ins just simply disappeared without warning.. The whole upgrade process felt eerily like the WIN-10 "free upgrade" of 2015. Dealing with the FF help desk feels very much like dealing with Microsquish these days. "We are sorry we dont support this and we dont support that anymore" ...the bookmark files folders are now Gray ..you want yellow folders? ....Helen Hunt has them ..so go to hell and hunt. After two weeks of frustration I switched to Chrome as my default browser.

It was supposed to be faster and it is,  trouble is at 5 seconds a click savings it will take me years to recover the 96 hours of non recursing effort I put into trying to get things I need to work right again.

I dont have a dog in this fight, too many variables ..but the link as posted works here in Chrome not in FF57, It will work in FF-57 if you remove both the <>. I couldn't get the link to work in IE with or without brackets?

I'm using Firefox, so it's not an uncommon browser, maybe it's a bug.

Seriously, just try hovering over your links, they show unequal brackets. Either both brackets need to be there, or neither.

Not trying to be a pain in the rear, but someone else IS going to have the same problem and not know why. So, I'm trying to help get future links posted, properly. I don't care, I know how to cut and paste to fix it, others might not.

No problem. I've worked with computers since IT meant, 'My terminal isn't working, so fix IT!' (I started in 1982) ;-)

Ok, just thought of another angle on this.

I use firefox to login to groups.io and respond to messages, not an email client.

So, I just checked my email client, and they show up correctly with paired brackets. If I login via groups.io, they DO NOT!

There's our automagic break routine --> groups.io UI

Sorry for muddling it up. But, now I know who the culprit is.

I use Firefox as well. It's email clients that usually cause the problems. I just highlight the URL, minus any brackets and right click 'Open in new tab'.

I post with the link between the pair of brackets, because some email clients break the links. The brackets aren't part of the URL, they simply tell non-compliant software to not break the links.

Maybe it's my browser, but I think it's truly a bad link(s), and I suspect other browsers may be "fixing" it on the fly.

If you copy or hover over your links, they all have ">" at the end, but not at the beginning. Unequal brackets, is invalid. Hence, why I suspect some browsers may be fixing it automagically.

No big deal, long as its working!

It is a valid link. I copied it directly from the browser.

<http://home.earthlink.net/~mike.terrell/index.html> is the home page.

<http://home.earthlink.net/~mike.terrell/Ephar.html> is the hardware page.

Sometimes Earthlink chokes on its own links.

Re: A "collection" with quite a few Tek 'scopes

Cool, thanks for the link. I see that they decided against the double-dip fee's, that creators and payers were gonna get stuck with (for now). They've blown their integrity all to hell though.

I wish they had a simple pay to watch method. I hate the monthly subscription model, for EVERYTHING these days. Any know if that is otherwise, for Patreon? I just click the "X" button when I see the word "monthly" on any website.

Happy New Year to all

Cheers!

Re: First draft of the Tek knob visual index project

I have a couple of the 323/324 scopes if you'd like photos of those knobs. It will be a few weeks before I can dig them out to remove the knobs to photo. I prefer to scan the faces on a flatbed scanner, for better lighting and detail. An example is the black knob on this page:

<http://home.earthlink.net/~mike.terrell/Ephar.html>

The website is quite old, and was built with hand written HTML so it is rather plain looking. Part of the site was lost by the host, or there would be more scanned images to show. The only updated page is the 'Current Projects', which I use to keep track of the test equipment that I have.

Subject: [TekScopes] First draft of the Tek knob visual index project

I have a 12 page PDF I can send to anybody interested of the beginning of the project, to show knob pics, data, layout format and other details. It is much too early to post, as only 3 sections are started, but I would like to get comments, error corrections, additional data and any suggestions if you feel like proofing it. just email me (off-list) to get a draft copy.

I especially need good pics of OLDER Tektronix knobs (or knobs I can photograph), from the 500 scope series and related vintage instruments, as I do not have many here, and none have part number data so far. this one area will really need some research work.

all the best for the new year to everybody.

Yes, in one (possibly more) of his Youtube video's he states his move to Patreon for his "training and educational" videos, if I remember any of it right. I didn't mean to imply he completely moved away from public YouTube, my bad there. But his intent was to provide better structured training videos with some income, can't blame him for that at all. Actually, I looked forward to it because I wanted to learn it, not just watch whatever he decides to demonstrate. I like that too, but that's more informational, than training. Maybe he ended up ditching the whole thing, have no idea.

The timing happened to be when I had other critical things going on, and had to put everything on the back burner. Probably a year ago now. So it was an easy decision just to drop off for the time being. I wasn't a big deal, I just was disappointed because I still wanted to follow along, but absolutely couldn't afford the time or money at that point. A little like paying for a gym membership and never going, been there done that.

Anyhow, I do fully support his endeavor, and when I have the funds to share, I will. I donated to Wikipedia and that tapped me out for now. choices.... sigh...
Ah, thanks for the extra context. I should have checked his Patreon
page, which also answers my question. He announces 37 patron-only posts
there. I guess YouTube is the main promotional avenue for these.

https://www.patreon.com/MrCarlsonsLab

Maybe I should pay a few patronage bucks to see what that material is
like, as an electronics learner!

If Patreon pulls more dirty tricks in 2018 (some feel their business
model/investors will require it) then I'd hope he'll be open to other
funding options.

Thanks for the image Chris, so those calibrators are more-less the same.
I have posted photos from this thread to a group album named "7A29

you wish, the album is public.
Hope you also manage to fix your units in a similar way,

I've just added a photo of the calibrator waveform viewed on my CSA803A to

2465B CTT calibration question

 
Edited

I need to run the CTT calibration routine to remove an error message but I don’t have pulse and time-mark generators. I have several function generators, signal generators, and a 1 MHz and 10 MHz TCXO. Can any of these be used to run the routine?


Re: Curved CRTs?

 

Drifting away from original subject that did remind me of one vacuum tube
oddity I have in my stash.
Is anyone familiar with the General Electric "light valve" used in the
Talaria projectors?

Documentation is included with the zip file. Specifically, Page 18 of the Field Upgrade Procedures:

"When signal-path compensation has completed, the oscilloscope is in the same state of calibration as before the loading of the new firmware."

Sounds like you should be relatively safe!

Still can't find my GPIB board, so I'll have to wait to try this... Anyone have a NI GPIB/TNT ISA board, they wanna trade something for (or possibly sell dirt cheap)?
