Dr. Steber is one of my favorite authors. He has published easy to follow articles on DIY VNA's and other instruments in QEX magazine and Nuts and Volts magazines over the years. Pretty much all those articles are available for download on the web. Its usually just a matter of waiting for some time after the initial magazine is published before selected articles start to appear.

Entire QEX magazine archives from 1982-2016 have been available at for some years now.

I don't have a subscription to QEX but if there is content that interests me I do purchase individual issues as a way of supporting the author and encouraging him to publish future articles.

From: Dave Daniel: Define “common knowledge”.

I would say anything that can be obtained from simply surfing the web.

On the other hand... (Copied from under Fair Use provisions):

In June 2011, Judge Philip Pro of the District of Nevada ruled in Righthaven v. Hoehn that the posting of an entire editorial article from the Las Vegas Review Journal in a comment as part of an online discussion was unarguably fair use. Judge Pro noted that "Noncommercial, nonprofit use is presumptively fair. ... Hoehn posted the Work as part of an online discussion. ... This purpose is consistent with comment, for which 17 U.S.C. § 107 provides fair use protection. ... It is undisputed that Hoehn posted the entire work in his comment on the Website. ... wholesale copying does not preclude a finding of fair use. ... there is no genuine issue of material fact that Hoehn's use of the Work was fair and summary judgment is appropriate." On appeal, the Court of Appeals for the Ninth Circuit ruled that Righthaven did not even have the standing needed to sue Hoehn for copyright infringement in the first place.

One of our members posted a document in the "Filed" section showing his upgrade procedure to a 3.2" screen @ /g/nanovna-users/files/Hardware%20Mods/NanoVNA%20new%203.2%20LCD%20display%20Herman%20ON1BES.pdf .

If you decide to go with a 2.8" replacement screen and have difficulty seeing the screen fonts then you might give hugen's 0.4.0AA firmware a try. It has a larger font size with the main penalty being only 4 memory storage locations instead of 5. See attachment for example display.

Many thanks to all for the valuable feedbacks

Will come back once I managed.

At the moment the app runs like a charm, but I prefer to publish it only once completed with the calibration part.

Hello,

Allow us, please, to announce that we uploaded our results, using our copy of Maxima
64-bit 5.43.0 running under our wxp64p&sp2, from our comparison of our formulation [1]
with that proposed by Erik, PD0EK [2], at:



Also allow us, please, to inform The Common User, who interested enough, that we
also uploaded this Maxima program by us, at:



Sincerely,

#89:

just select the 2nd pic to get the touchscreen version.

try this,its biggfer but will work:

I don't have the information you seek; however there is a larger version of the nano selling for around $150.? You might consider this as an opportunity to get a larger screen.? The original is painfully small.? In some cases I find need to use a magnifying glass.
Compounding this is the fact that young engineers don't seem to have a grasp of hardware and those who do aren't young (such as myself) and so have vision issues.
Perhaps you can locate a donor unit that has failed in some other way.

My VNA arrived with a busted screen, very bad packaging, unit works when connected to my computer.
I received a full refund from Amazon despite what the vendor wanted which was a 40% refund..
I would like to replace the screen but can't find a model or part number for it.
As suggestions would be greatly appreciated.
Thanks for the help!

But that does not include wide re-publication .

Ron, of course anyone is entitled to have a copyright for his writings.? That's part of what makes the free enterprise system as good as it is.? (And it isn't always so good.)
Nobody should complain if someone wants to be paid for his efforts.? And if he decides to give it away no charge, that's his business.
I agree that it would be nice to get all this hobby related stuff without shelling out money but that's not the siruation here.? The operative word is 'hobby' and many resent someone who wants to profit from it.
The world is what it is and no one of us can change it by very much.

Hopefully this will get fixed in Rune's next release. Are you around Rune??

Dear Erik,

If we understand correctly, we have to start from [1]:




and transfer * c o r r e c t l y * their equations to Maxima, as in [1]:



and/or as in [2]:

/g/nanovna-users/attachment/8473/0/Check.PNG

But, we think that, as it seems, there is a wrong transferring of them
regarding some signs, as well as an interchanging of small letters
with capital ones regarding the names of variables.

Would you check for us, please, these two particular points ?

Best regards,

gin&pez@arg
