I bought that exact one, but with the terminator kit. A friend told me it has a much nicer case than his. It works fine. I've spend days on end measuring everything in sight on my workbench. Components, various filters, questionable coax, homebrew circuits I've built over the years. Everything but antennas. Made a BNC calibrator set. Designed and printed some 3D fixtures for it which are posted on Thingiverse.com. Very instructive. No problems with it at all.

Same here. My interests are restricted to <30 MHz. There are important behaviors above that, but well within the 900 MHz limit. I use mine for the bench. I have a tribander at 60', a 40m dipole and an EFHW for camping. I already know their characteristics and as long as they appear to be working normally, I don't much bother with them anymore. But on the bench, the little VNA has opened up possibilities that were tedious before, and helped me understand circuit theory that I never really understood until now.

It will take awhile to get the hang of navigating the menu system, but it's worth getting proficient at it even if you decide to use the PC or Android software. I found this book helpful for getting started: Eric KE6US On 3/27/2020 5:48 PM, Louis Warner wrote:

This is the 900Mhz version. I would get the 1.5 Ghz version

OK I am trying to order it but turns out they don't send to US PO Box addresses which in this case is my only practical option. Why in the world would you put such a stupid restriction on this small sized purchase??? Unless this is being drop-shipped which I would not be surprised at all give amazon's sales system where you never know from where you are really getting your item from. This is why I hate amazon, and will wait for it to turn up on ebay at a similar price and zero complications.
SORRY AURSINC: NO SALE TODAY. |
The problem with P O Box is the battery in the VNA.

PO rules prohibit a lot of things that burn and record how the parcel was shook in transit. Amazon follows the rules, but some of the flighty others don't. Or you get a VNA with out a battery. Could suggest a friend to drop ship to Good luck On Sun, Mar 29, 2020, 11:33 AM <nanovnagroup@...> wrote:

Or an amazon drop box if one is not far away. They are all over the place. The local Rite Aid, Ralphs,? UPS Store and health food store all have them within two miles of me.

That is absolutely not true. The only restriction for Lithium batteries (or any other hazardous materials) is air freight. Nothing to do with a PO Box being the final recipient. The problem is not at the destination, but rather in the process to get it there. I have received many times various Lithium batteries for radios, cell phones etc, even the backup cell I needed to refit in my HP3468A DMM via my PO Box absolutely without any issues. Some of the bigger packages even had the Lithium battery inside sticker warning as required. The ONLY valid reason to exclude a PO Box is if the shipment is being sent by UPS, Fedex, or DHL, which require a signature upon delivery, so they do not deliver to a PO Box address. There are US based sellers on ebay (a lot of them chinese) that advertise shipping with USPS in capital big letters and still exclude PO Box on various smallish items, nothing hazardous. The reason is usually that they are drop shipping, and are not really the entity that will handle the shipping so they have no control over it, and are not even able to provide you with a tracking number, or just send you a fake one. Sometimes you end up with an Amazon box even tough you made your purchase on ebay. Been there seen it happen, now I steer clear of any seller that is US based that excludes PO Box. Something funny going on there for sure. Life is short why waste time with drop-shippers. And as I said before, the PO Box address is my ONLY practical option for small packages. I am not in the US. I do have a street address as well, but only for freight cargo so it has a base charge and does not make sense for small items. Been doing mail forwarding for many years with 99.99% success rate. |
I ordered mine from this Amazon vendor:
shorturl.at/ahsS7 Order placed on Saturday, Amazon said it would arrive Monday (today) but it was delivered at noon yesterday, 20 hours after placing the order. Compared to the first of these nanoVNA's I ordered 6 months ago, this one seems much more refined in terms of packaging, having a hard case included, etc. -- John AE5X |
Well John, I'm sure that you love me but what the heck is up with that link?
