Forgot the attachment. In both 0.1.3 and 0.1.2 the "Hz/step" field is blank. Prior to 0.1.2 the calculated value was shown in the field. Herb

Hi Herb, I don't see an attachment :-) I have attempted to make the code more resilient to that particular phenomenon, so if you can describe the exact steps that cause it, that would be most

Rune, As usual, kudo's on the latest 0.1.3 update. As I noted on the 0.1.2 update, the "Hz/step" value seems to have gotten lost (blank field), see attached screenshot. - Herb

Hi Mel, I'm not entirely sure what you wanted to say with your comment, which needed to be said, though? Was it related to series R + X, as requested by Martin? I'm not sure where the Smith chart

A standard PC USB HD camera connected to your PC should be able to be re-focused for close-up work.You just need a stand to hold it above the item you're working on.Even the cheap ones from the dollar

The current display is in smith chart with Magnitude and phase, and or on SWR just that, No R and j. R is the resistive component of the signal and j is the computed reactive element in ohms of the

Getting Ft from measured S data is pretty straight forward. The key is you DO NOT NEED TO MEASURE TO THE POINT OF UNITY CURRENT GAIN! Simply take a couple of points say at 10 MHz and 100 MHz. You will

I have downloaded the NanoVNA WebApp to my Samsung S8 which has a USB C connector. I've read issues about USB C to USB C connection issues without the 5.1k pullup resistors so I want to get a USB-C to

Per the AM Forum site this is the pointer they provided. Not sure if this is the site Warren used.

Part of my problem was that I misremembered the formula. Besides, I have to calibrate my test set.

Thanks, I'll get that fixed in the next version :-) Didn't catch that one during the testing, clearly ;-) -- Rune / 5Q5R

Thanks Rune, when I said "considerable improvement" I was talking about the better visibility it provides OFs like me with macular degeneration, cataracts, etc. However, I think there is a slight bug

Right click the charts. :-) -- Rune / 5Q5R

Sorry, I can't seem to locate the fixed scaling options. Where are they?

You're right, Raymond! I forgot about that. I still need to do *more* with it - it breaks in places. But I guess as long as people don't complain about it ... ;-) -- Rune / 5Q5R

One "minor change" I like a lot is the better handling of the (X-axis) numerals in my graphs. Say, I'm using a span of 100 kHz around 20 MHz. "Return loss" and "Gain" graphs now show two decimals

If you check out Wiki Application Notes, then you will discover some are simply links to useful messages. If "Application Notes" seems too stuffy or ambitious, we could start a Wiki "How-To" page.

Very nice ...Several of the older data books also show test circuits for individual transistors ...I've been contemplating making some measurements of Ft/Ic for various known/unknown...unknown/unknown

W5DXP, thanks - don't make it sound like it was horrible before ;-) -- Rune / 5Q5R
