I know, that some TEA members have bought a NanoVNA 2.
A few minutes ago I've found this email in my inbox:
(You are receiving this email because you've ordered a NanoVNA V2 from
our store on Tindie).
Hi, we've recently seen a large amount of ePacket shipments take over
60 days to arrive. We are in contact with China Post, who said that
that packages are slow to leave Shanghai airport due to lack of
flights. We would greatly appreciate your patience at this time, and
apologize for the inconvenience caused. China Post has assured us that
your shipments are not lost, they are just waiting for a flight.
Following Aliexpress's moves we will be extending the order protection
time to 120 days. If your order does not arrive within 120 days of
shipment, or if tracking shows that the package has been returned,
please contact us and we will be sure to give you a resolution.
If you have any questions please use the nanovna-v2 support forum,
which we check regularly:

Thanks
- HJ
Just in case, if you are curious where your NanoVNA 2 is.
I should have my .6A slow blow fuses tomorrow from Mouser...then will be the moment of truth on whether that 184 actually works or not. The seller offered me a partial refund, but I haven't gotten any reply on a proposed amount...
Got the fuses. Good news and bad news. Good news no fireworks on power up. Bad news, it's definitely not fully working. Only some markers are stable. Others are unstable. Troubleshootin time!
After a nice long warm up, alignment, and much control exercising, the 184 is 95% working. The other 5% is the H.F. sine marker function, which appears to be dead as a doornail.
Also, FWIW, the power supply is completely in spec. All three rails are correct voltages and ripple is better than specified.
As usual, I find myself behind in the conversation. Yes, I actually went through 30 pages or so to catch up, instead of asking Cubdriver for a synopsis
With computers being a common topic, I did try to pull my old laptop off the dust pile and fire it up. I thought it only sat there on the pile a few months. Must have been longer since it was next to useless. It has an Intel N270 running Windows XP Time to experiment; I am thinking of trying xubuntu 18 but open to recommendations of suitable OS for a small boat anchor.
Rack of ribs has been rubbed with Montreal Steak seasoning, seared both sides & slathered in a layer of the good stuff; now for the "Texas Crutch" : Seal it all up in aluminum foil and roast at 275-295°F. In a couple hours should be fall off the bone tender and ready for the final coats of sauce.

You missed the best pro framing hammer Estwing ever made:

When I worked interior construction & make-ready out of a Bucket Boss, the E22L (same hammer in leather grip) was my "everyday" hammer; again, an awesome peg-beater. Too effing long for a toolbox hammer tho.
Grand-dad was a great bear of a man... he favored a E30L in leather grip. That fucking this is a toothpick short of a post maul.

And now on to ..the story to my Frankenstein-Agilent 8110A:
...
After all it was fun to build at least two working 8110As from parts of three 8110As.
I might sell the one-channel unit to get money for future TEA projects.
At the moment I enjoy having not one but two 8110A pulse gens.
-That I don't really need.
Pure TEA.

Deoxit and IPA wash on the RF selector get back the 5ns but the 2ns output level still noisy and below the required level on my unit.

I run xubuntu 14.04 (haven't bothered to upgrade, so I don't know about 18.04) on a 10yo netbook with an 1.6GHz Atom processor. That was WinXP until the disk died and Microsoft refused to allow me to reinstall it.
It is just fine, even on the low-resolution screen.
If there's ever a problem with the forum, I have an OC-48 here now and willing to host anything necessary, for free!...
Tek (and other goodies) alert!
Anyone in or near Santa Barbara, California? Pick up only.

Did Cubdriver say he was heading west?
@BU508A Many thanks for your piece of filter material, it arrived today along with your surprise package to keep it company during the posting, it does get kind a lonely I guess in an envelope I'm sure that I can find a use for them somewhere along the way. Here are a couple of photos with the filter installed and lit, beautiful contrast now

My pleasure.
That was exactly my thought. Traveling alone can be sooo boring. I got an omnibus volume of some electronic parts from Rohde & Schwarz and it contained a huge amount of those µA709 OpAmps and I thought, they could be a nice company.
Glad, that you've enjoyed it.
The x-tal tester is looking much nicer with that filter, isn't it?
You missed the best pro framing hammer Estwing ever made:
https://www.amazon.com/dp/B0000224V9/ref=dp_cerb_1Agree, that is what a workmans hammer looks like, the others look like they should be in a display case
... just a question: Does you omnibus also contain vintage transistors (TO-18) ? I am working on some esoteric oscillator project where I need *old* parts that have not been made using modern production processes.

Am I the only one curious to know what Dave does think about us? He barely mention us.
PS: A big thank to you all, not only we do not need a mod, but also there is always something interesting to learn here and the tech level is very high for my standards.I think you'll find that Dave does some moderation himself and there are others that help. If you watch many of his videos he often mentions us in them as we are now one of if the biggest threads on the forum and I think that he is very proud of his forum and rightly so. I understand that it is possibly the largest in the world but I do often wonder just how much longer he can continue to finance it given the current state of the world. I think we owe a lot to Dave for his generosity in provided us with this lovely platform and I for one salute him.
Well said, Zucca & Spec. I concur.
BTW, this thread is now not only the largest thread by number of replies, it's also #1 in total views.

Oh, my. I haven't seen a OC-48 in civilian production use in more than 10 years. Sweden backbones are 10G (rare) or 100G (in multiples) Ethernet today. Access to customers is 1GE or 10GE.
Not that I mind OC-48. SDH/SONET, especially Packet over SONET, is a much more complete solution catering to the complex environment of WAN connections. The carrier industry seems to be on the path to reinventing all features of PoS in Ethernet, though, what with BFD, LLDP, SyncE, IEEE1588, etc. Some of it is good, other parts sport all the tell-tale signs of a royal bodge.
Since my last checking, bd139 managed to climb up two positions of the top 10 posters here.
