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. Dennis Tillman W7pF From: Colin Herbert [mailto:colingherbert@blueyonder.co.uk] Sent: Monday, November 02, 2020 9:59 AM To: dennis@ridesoft.com Subject: RE: TM500 and TM5000 Prototyping Boards for Sale 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?
Tom Lee
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.

Roy Thistle
High All:
Ever seen Tek probes for sale on the bay?... where the probe's coax has been bundled up...like you used to bundle up a piece of very flexible rope, back in Boy Scouts... or the coax is folded round and round, in a coil... then all squished together, at the middle... and a twist tie, elastic band, or tie wrap...fitted around. What's behind that? That can't be good for the coax... do you think? ... especially, high-frequency probes. Regards. Roy

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?

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. Dennis Tillman W7pF -- Dennis Tillman W7pF TekScopes Moderator

My apologies for including the Mailwasher detailed header information in my last post. I should have realized this was a mistake. I have deleted it from TekScopes along with the other similar messages that included the Mailwasher detailed header information. I believe that was an inadvertent mistake and not intentional. To the members whose post I deleted because of the detailed header information that shouldn't have been there: Please feel free to resend your message without the detailed header information.

Howdy folks,
Anyone have a PAPER manual for the Tek 5D10 plug in for the 5116 scope that they would part with for a reasonable amount? Thanks. Dan (kaboomdk@yahoo.com and I'll take replies off-line).

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.

The From: field in the email header is trivial to forge. If you
toggle quoted messageShow quoted text
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. Paul

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. Dennis Tillman W7pF
