I have been using a fixed L and a fixed C on 3.5 and 10 MHz. Works very well in getting a quick check of calibration. Mel, K6KBE

#52 : Update : The compact SLO formula for [AnyVNA] - after /g/nanovna-users/message/5081 - 17 October 2019 /g/nanovna-users/message/5075 - 17 October 2019 by Gary

Perhaps calibrating nanoVNA THRU using an RF Active Probe, e.g. https://www.ebay.com/itm/332393676082

Hugen, If I order a NanoVNA-H today will it have the 5.1k Type-C CC resistors installed? What is the link to your Nan0VNA-H site? If someone does not have a NanoVNA with the resistors does this

Hi Perhaps the caption should have been "nanovna-saver – a premature look". I mean it is of version 0.1.0. I took a different approach than writing a blog entry, or webpage, about it, namely to

Wow - you have a lot of time to look up all of these posts!Are you going to put all this in the application notes section of the wiki? Enhancing nanoVNA by an eBay 3GHz RF bridge is interesting.

Enhancing nanoVNA by an eBay 3GHz RF bridge is interesting. Before getting nanoVNA, I considered using SDR and noise source with http://transverters-store.com/rf_bridge/rf_bridge.html eBay clone

Hi Rune , very happy for the new improvement on the 0.1.3 of nanovna-saver. Suggestions for the future version : 1 Save the settings of nanovna , start stop center number segments , sweep mode , when

Citing in messages helpful specific URLs applicable to nanoVNA (and why) has value.

Hi Rune, I still can't find my old paper notes on the subject of Cs, Cp, Ls and Lp but this Keysight document seems to be the closest to what I was looking for. Section 1 of this document

Because in my experience he is usually correct in what he says, and his blog postings lead to greater understanding of various subjects, mainly due to him challenging what others may take for granted,

A dedicated USB attachment, stripped of display, battery, and switches would be nicely light weight and efficient

The question is, why would anyone care what Mr. Duffy has to say?

Yes I thought that something like that would happen. If I put a tuned circuit on the collector/drain and match it to 50 ohms, it will not tell the true Hfe. Perhaps a 500 ohms reactance would work in

While Mr. Duffy was rather unkind to both the NanoVNA and Mr. Broberg, he does have an interesting blog. Here he talks about improvised test jigs https://owenduffy.net/blog/?p=15710 Jim, KA6TPR

Some people said that you can solder anything you see, so get a magnifying glass. I dont beliewe that is always true but maybe you can. Leave coffee out for a while and try. I can just use 0603 with

From: necessaryevil86@... What I want is a slightly larger display, a 3.2" or a 3.5" is not that much more expensive... But I also know: the most dangerous thing in the world beside a programmer

Hi Rune, I have a suggestion. If one tries to adjust a homebrew filter of any kind it would be very helpful to see the result of the adjustment at least for S21 and S11 simultaneously on one plot. In

Hi Gary, I am aware of the scaling issues. It occurs primarily (only?) when values grow "quite large" or "quite small", and thus can't fit in the assigned fields. I haven't made the fields fixed size,

Hi I see the resizing too. Reported to Rune. The problem, as I see it, is that the panes with the marker numbers are auto sized/not fixed in size. Bo
