Re: We started selling SAA2 with N-type RF connector and 4-inch display

 

There is no shipping method available for Serbia.
Also the store does not list any products, all are hidden for some reason.
I presume that is intentional but just in case ...

There is no innovation, just a new shell.
Since this group has been dissatisfied with the SMA connector and the
2.8-inch display, we installed the N-type RF connector and the 4-inch LCD
on the original SAA2 and fixed it with a metal shell. The increase in cost
mainly comes from N-type connectors and radio frequency cables containing
N-type connectors. In order to avoid confusion with the next-generation
products that may appear, we temporarily call it SAA-2N.
The N-type connector is very heavy, and the total shipment is 1kg. The
logistics company may need to charge a logistics fee of 1.5kg, so the
logistics cost is much higher. We are waiting for the MSDS report of the
new battery. After the MSDS test is completed, we will provide DHL shipping
methods.

As some users cannot complete payment in alibaba, we have activated
aliexpress and support paypal payment.

Re: NanoVNA-Saver installation macos. #nanovna-saver #macos #problem

 

Mike,

Thanks for very easy to understand instructions. I have the Saver installed on my shack computer (Linux), and want to put it on my Mac Book to take into the field.

Re: NanoVNA-Saver on Linux Mint 19.3

 

Hello, Nick:

When the issue came up, I started doing cut/paste from your PDF to make sure I wasn't making a typo or adding extra lines. Same results.

I tried Firefox, Chrome, and Chromium browsers and all can reach/read the bootstrap server.

I rolled back everything, removing the Python 3.7, Python 3.7-venv, and GIT (using apt purge), deleting all the directories and their contents. I still get the following when I try Step 7:

=====

=====

I noted that my total received data is 1840k, the same as your test earlier, but both are different from the PDF (1734k). I doubt that matters.

I'm running Linux Mint 19.3 (all updates applied) for amd64 with an AMD FX-8320E CPU, 24G RAM.

Thanks so much for your help!

Take Care & 73

Also more durable

Decent N connectors work to at least 18 GHz. My 18 GH HP 85054B N cal kit
is N connectors.





They female inners are slotless, but cheaper connectors with 4 or 6 slots
work to 18 GHz to. In fact, they work above 18 GHz, but I don¡¯t know how
high. My HP 22 GHz spectrum analyzer uses N, but my HP 20 GHz VNA uses 3.5

PS for my work better use N-type connectors, all devices have it, also all
my good calibration kits for N-type

Re: NanoVNA-Saver installation macos. #nanovna-saver #macos #problem

 

1. In 'Terminal' open a new window. shell->new window->basic
Ignore the 'update your account to use zsh' or you will regret it.
2. Download the latest release from
This is on the right of the main page under Releases. It looks like:
NanoVNASaver.macos-latest.zip
3. Drag the zip to your desktop.
4. Select between the semicolans here:
'shasum -a256 '
copy and paste or drag n drop with the mouse to the terminal window. Don't miss the space after the 6
5. Drag n drop the NanoVNASaver.macos-latest.zip icon into the terminal window, click in the terminal window and hit return.
6. Note the long number and be sure some of it matches the SHA256sums on the download page.
7. Double click the zip to open.
8. Back in terminal type 'cd ' without the semi's but with a space to change to directory
9. Drag the unzipped folder you created to the terminal, it should fill in the name, then hit return.
Check that you are in the correct directory by 'pwd' (print working directory) or 'ls' to get a list of the files in the current directory.

10. Now you can copy 'chmod +x nanovna-saver' and hit return in the terminal.
11. And 'xattr -rd com.apple.quarantine' and hit return.

12. Now either type ./nanovna-saver or ./na followed by tab key to have it auto filled and hit return or back in the folder on the desktop double click nanovna-saver like a normal mac app.

First I think you must have Xcode installed and the 'command line tools'. I can't verify this cause Im not going to remove it !

=====================================

Fred,
Only the AliExpress link supports direct Paypal payment. I just pre-ordered one from there and it works fine. The 4'' display and re-location of the buttons were the main incentives for me. Like DiSlord, most of my other equipment has type N connectors and I have a lot of high quality cables with type N connectors. It will be interesting to see how good the type N standards are. hugen is usually pretty good with his sources.

The photos show the Saa-2N is packaged in a metal case with retaining nuts on the type N connectors, so there should be little stress on the pcb connection. Only time will tell.

I'll donate my 2.8" SAA-2 to one of my ham club members.

Re: Threshold Console Command Explanation

 

Assuming my interest in nanoVNA is up to 500 Mhz.
Can I improve something, say, by adjusting to 200 Mhz?
Thank you!

Notes for others...
the PayPal method is not shown until you get to step 2
only Estimated Delivery on 10/13 Shipping: US $21.98 AliExpress Standard Shipping is available

so you must wait to order if you want DHL...and even then, it might still be Oct...?

UUT: a 3meter cable with 50 ohm coax 32 AWG, note the cables terminating connectors are not impedance controlled.

Calibration: calibration was completed, short (cap), load (cap), open (cap), through (a 50 ohm cable) which I cut in half and soldered to UUT connectors.

Is this phase plot and jagged smith plot due to excessive capacitance crashing the nanovna source (we expect ~300pF total, being 32 AWG coax and given the 3m length)?
