I send money to friends and family through PAY PAL and there are no charges to the sender as far as I can see. I have sent my son and others many hundreds of $$$ over the years without a fee. All USA transactions in USD, so other countries and currencies may incur fees.

Yes. I've seen pictures of them with both German and Russian labelling, but no other languages, even here in Poland. I have some German-language instruction manuals which have pencil annotations in Polish.

I can already see one thing that the Russians improved: the latch won't break.
Having played with the plugins a bit, there's another reason for that: the edge connector is a somewhat finer pitch than the Tek one (has more contacts) and so alignment seems more critical. Even slight movements of the plugin make the readout go crazy. The mechanical tolerances seem a little more generous, such that it's sometimes necessary to loosen one plugin to get another in next door to it, so everything shuffles around a bit until the screws are tightened.

But how come one of them doesn't have a latch?
That's the delay line which, analogous to the Tek 7M11, is entirely passive (has no edge connector or other connection to the mainframe). It's also incredibly heavy, presumably being full of hardline coax. Maybe they intended it to be mostly used outside the mainframe. If fitted in the mainframe, however, there's a real risk of it falling out and injuring someone's foot!

Looking forward to the non-potato pictures.

A comment:

Searchable is probably hard.

A set of specific Tags seem to be missing

e.g.
 7000 series, case history (repair), options, photos, Non-OEM parts, 3D Printed parts; Horizontal, Vertical, Photo, power supply, symptom: xxx, Theory

Tags should be from an approved list.

e.g. search case history; vertical;

It's almost like a Blog and blogs are tough to search.

Yes, it is, as far as I can see. Having spent a few minutes playing around with it, it seems that the sampling timebase has no ability to free-run or obtain an internal trigger signal. It needs an external trigger, which is provided by the pulse generator (or, I guess, the trigger output of the delay line if you're observing an external signal). The only way I could get a trace out of the sampling timebase was to connect the trigger output of the pulse generator to its trigger input. Then both repetitive sweep and manual/external scan work fine. The sampling vertical plugin appears to do sensible things, too, so I'm really itching to get my hands on the sampling head.

I'll have a look at the risetime of the pulse generator too. It may be a useful tool in its own right!

The standard timebase doesn't seem to be quite working properly. It will only sweep in response to each press of the single-sweep-reset button, though it does trigger correctly each time. It's as if it's getting stuck in the holdoff state. The sweep is offset to the left, too. I'll do the usual edge-connector-cleaning routine and see if that helps, otherwise it's time to break the factory seals, which is a shame. However, I've already spotted a couple of tunnel diodes visible through the perforated side panels :-)

I snapped this one up because it's in great shape (all the plugins still have their factory seals intact) and it has an interesting selection of plugins.

The haul includes:
C1-122 (S1-122) mainframe
Ya4S-89 pulse generator
Ya4S-90 dual trace vertical (x2)
Ya4S-91 dual timebase
Ya4S-97 multimeter
Ya4S-100 dual trace sampling vertical
Ya4S-101 sampling timebase
Ya4S-102 dual delay line
2K11 calibration plugin

So far I've only had time for the briefest of tests, but the mainframe basically works, with readouts on the screen, and I have managed to get a trace out of it. I'm looking forward to experimenting and documenting it in more detail on TekWiki. It's like familiar technology but from a parallel universe!

One thing I really want is the sampling head to go with the Ya4S-100 plugin. The seller is hunting around to see if he's got it anywhere, and I'll keep looking, but otherwise it might be a case of improvising with a 'western' sampling head to get it working.

Yup. I'm a member of the Racal RA17 and Marconi lists and a couple of others I forget because there

Re: OT : How About A Group For "Other" ?

I am sort of lost in this very long thread but will chime in FWIW. I belong to the Hewlett-Packard/Agilent/Keysite group. Some time ago a few of us decided to start another group dedicated to Boonton Radio, which became a division of -hp-. The group showed some activity at first but eventually sort of faded out although it is still going. There were several unrelated companies with Booton in their names and all get discussed in this group and are welcome because there just isn't enough Boonton Radio discussion to support it.
I think splitting a group or list makes some sense if there are a lot of semi-off-topic subjects where another list can be supported. Otherwise I am skeptical of its having any advantages.
I have only a couple of rather ancient Tek instruments, both of which are in constant use (except the scope I am working on) and appreciate the expertise and generally high level of understanding here.
I may add that there are many mailing lists and forums (forae) dedicated to various makes of test instruments and even to generic types of instruments. I would suggest making sure that any new group actually serves a purpose.

I already emailed the site fro some clarification. I am going to need some help for sure. I use direct web access to get here and it works fine for me, however I guess many use an email client. I never learned how to set one up. I have Outlook Express and real Outlook, and I have used Thunderbird for Usenet access when Google was down. If I open one of these email programs it wants numbers which I don't have, so a walkthrough on that would be appreciated. I will also Google it of course but sometimes it is better to hear it fro people. I may know a little electronics but internet and all this, not so much. The PC itself, maybe. I have built a few and repaired some, and got rid of bugs etc. for people and myself. I am not afraid of the registry though I avoid it for obvious reasons if there is a better way to git er dun.
One question is say I want to include my guidelines for images, I see nowhere to put that. Do I have to put it right in the group description ? That is one mess I do not want to create so I think it should be nipped in the bud.
Hopefully this will work out and people can go there and discuss their HP, Sencore, Wavetek, Boonton, whatever. But it is right in the description on to refer here anything to do with Tektronix oscilloscopes.

Re: PAYING FOR GROUPS.IO

 

I agree with the idea of an ebay donation format through paypal.

On another subject: While working with Groups.io, how about an option to receive or not attachments? This would allow those with bandwidth or security concerns to opt out of receiving the content. The rest of us with broadband connections could get the jpg or pdf docs inline with the messages.

Just a thought.

Stefan's eBay plan is brilliantly simple!
But I say it should be extended to $200, so there are ample funds for the eBay and PayPal fees and other administrative costs (such as a nice lunch for Dennis and his wife, etc).
Do not give any accounting of the funds other than to say the first year is paid for.
Forget the list of donors and forget giving credit to anyone who contributed.
If anyone requires a 'pat on the back', or any kind of accounting, then that person should not contribute anything, and just say he did if it makes him feel better.
Then when the time nears for the second year payment to Groups.IO do it again for double whatever the Groups.IO charges are at that time.

My 1cent...

Paypal slightly preferable, fleabay acceptable.

I don't care if Paypal takes a cut. If I contribute, say, $5, then I don't care how much is wasted. $5 would be far less than the value I receive from other people's postings!

I don't care if someone makes a modest profit. Basically I trust the individuals involved to Do The Right Thing.

If every "member" contributed $1, then it wouldn't run out in my lifetime :)

Just my two cents:

Ask the people of groups.io if it is possible to have two "sticky" messages always on top of the list so new users and existing users too can read.

First explain the basics of how to use, eg. How to create a new message and a new album using the same name, copy/paste the link to the album in the new message so the relevant images are easy to find when reading the thread.

Second sticky: explain the free usage of this group and the relative small amount per user needed to keep it alive and put a "PayPal donate link" in there?

I prefer PayPal too.

I see we've already had an offer of server space so why not set up a "pledge" page to start with? We go along and put our names on the list to certify we will donate (say $1).
We then have an idea of the likely amount that will be raised.
My vote's with paypal, btw.
