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

Hello again GIN & PEZ I wish to have some clarification that I am interpreting the test configuration correctly. What were the Putty commands you used to extract data from the NanoVNA? Can you confirm

That is great idea. Most people need nanoVNA for quite simple tasks. That said, there are number of useful tutorials on YouTube. Listing them would also help new users. -- 73, Pedja YT9TP Checkout:

Oristo, I also ordered two if those, and a couple of 10 db attenuators. They look like a good test jig for experimenting with small components or transformers. I have one of the $9.00 eBay bridges,

KE8CPD6, I had the same issue as you. After clearing the config data and recalibrate, it seems to work OK. Here is what I did. - Plug in the USB - Use putty or any terminal software to connect to

Well if you can stand the wait, ten bucks (in total) could get you a (small) boat load assortment of sma resistors in maybe 30 +/- values (prob. 10-20 each) from China. Might as well grab some caps,

Hello again GIN & PEZ; Your #51 full final report is a much improved compilation but as mentioned earlier, it is quite difficult to read and follow, much less comprehend, when it requires navigating

The newly released NanoVNA-H has added the 5.1K Type-C CC resistors, which is already installed if it have a "NanoVNA-H V3.3" tag on your PCB.

Well, what is wrong with making a dedicated cable by cutting it, use a small elongated perf board (or etched board? wiring it one to one with the resistors on the board and heat shrinking it all back

Good Evening Everyone, It looks like this thread has kinda died a bit. I am still without a fix for my issue. I tried again to updated the firmware this evening and still ran into issues above 300mhz.
