FW: TM500 and TM5000 Prototyping Boards for Sale

 

Hi Colin,

I replied to your request earlier today but I received a notice just now
that my mail could not be delivered to you. This has happened many times in
the past few months when I replied to your emails. Often it takes almost a
week before my email finally gets through to you.

Please contact me directly with an alternate email address I can use to
reach you.

Hi Dennis,

Do you have any of these boards still available? I tried buying a
supposedly-compatible Vector board from a seller on eBay a few months ago,
and the eBay Global Shipping system messed-up right royally. It has been
stuck in Erlanger for the best part of two months! Needless to say, this
isn't the sellers' fault, so he isn't prepared to give a refund. I have
moaned at eBay but they seem to have done little. This is after paying not
only shipping, but also Customs clearance and Import Duty, so I'm rather
annoyed. Anyway, this is my problem and loss and I am probably boring you -
sorry about the rant. I am trying to make one of those TM5xx testers
plug-ins (067-1201-99) using the frame of a Metrotek MR 101 Receiver that I
acquired. I suppose that if the Metrotek is of any value to someone (it
isn't to me) then I might try to pass it on and use something else to house
the tester. I recall that the boards were $US20 back last year but I suppose
the shipping to the UK might be a bit more than the $US5 that was quoted
then. I live in London, UK.

TIA, Colin.


Re: Folded up (folding up) the coax on (Tek) probes: not good, right?

It's probably not nearly as bad as you fear unless the cinching is so extreme that the dielectric gets pinched to the point of permanent deformation. Anything's possible, of course, but twist ties and standard-issue humans don't ordinarily do that.

A P6131 without a broken tip... or do you mean which different Tek probe... et. al., is a good substitution/replacement?
From TekWiki:
The Tektronix P6131 is a passive miniature 300 MHz ×10 scope probe for 1 MΩ // 14-18 pF scope inputs.It has a ×10 readout pin, and shares accessories with many other Tektronix subminiature modular probes.
Do you have a Tek 24XX scope, that needs the P6131 bandwidth? ... and you need a mini-probe?

Thanks Dennis (and others)! I know that was not intended; but these
things can snowball pretty quickly.

Thanks again! And now back to our regularly scheduled program ...

You have been removed from TekScopes@groups.io

 

Hi Geoffrey,

Thank you for the tip about Mailwasher. I downloaded and installed it after reading the reviews. They were all 4 or 5 out of 5. It looks like an excellent way to deal with SPAM. Several months ago someone got hold of my email address and I began getting numerous emails from women for some porn site. If I had Mailwasher when that happened it would have been a real help. Instead, one by one, I added them to my block list and gradually these SPAM emails stopped. But it took time to do that each day and I was working on a project that had a deadline and I had no time to waste.

I often find that, if I examine the url or email address that the message wants me to click on or respond to, I find that it is obviously bogus (sometimes in another country), confirming my suspicion that the message is fraudulent. My email program (claws-mail) makes this easy; I do not know about others.

What is a good replacement for a P6131 with broken tip?

Subject: Re: [TekScopes] Tek Probe P6131 replacement tip ?

Hi:
Did you look at the exploded drawing in the "P6131 Instruction Manual"?
I think you are referring to the "probe tip."
From:
"Figure 10: P6131 probe with standard accessories"
and the table:
"Replaceable parts: P6131 probe and standard accessories"
206–0265–10 "TIP,PROBE:10X,10.3PF,CLEAR/BLUE(STANDARD ONLY)" or
206–0265–12 "TIP,PROBE:10X,12.5PF,CLEAR YELLOW(OPTION 02 ONLY)"
I've seen this part(s) (probe tips) come up on Ebay... and it used to be sold by Tektronix; but, the P6131 is obsolete, so I don't think they sell the probe, or parts for it, anymore.


Re: Fw: You have been removed from TekScopes@groups.io

Paul Amaranth
 

The From: field in the email header is trivial to forge. If you
really want to see where the mail originated, you need to look
at the Received: header in the full list. Most mail programs
will let you look at that, although not usually by default.

My Tekscopes mail, for example, has a Received header that looks
something like this:

Received: from web01.groups.io (web01.groups.io [66.175.222.12])

Reasonable, since it comes from groups.io. If it doesn't say
groups.io, it's not a real Tekscopes email.

I spent 12 years doing computer security and about once a week
I get an email that takes close examination to verify that it's
a fraud. Some of them are really good. Note that I said verify.
If it looks odd, it's probably fake. EVERYBODY'S A TARGET and
social engineering is incredibly effective.

Note the phrasing, that's often a big clue. A real email (if it
actually existed) would more likely say "you're unsubscribed from
Tekscopes at groups.io", and not use the email address of the group.
Or, it would be more to the point since a moderator was sending
you a note. You may be so upset about the subject (Wait! I didn't
do anything!) that you may overlook details like that. That's
by design.

Sometimes I do follow the link (using appropriate tools), but that's
only to see what kind of obfuscated javascript payload they're trying
to deliver.

Re: Fw: You have been removed from TekScopes@groups.io

 

Hi Thomas,
I checked your membership. According to the TekScopes database you were never removed and you are still an active member.
You can confirm this for yourself since you are able to send messages to TekScopes regarding this issue and you have responded to several other TekScopes members about the message you received.

I can't explain the notice you received about being removed but I think that if you examine it carefully you will find evidence it did not come from TekScopes or Groups.io.
